Topic: ERMES: An Earth obseRvation Model based RicE information Service, European Project

Speaker: Ramin Azar, GIS & Remote Sensing specialist, Former Research Consultant at National Research Council, Institute for Electromagnetic Sensing of the Environment, Milan, Italy (CNR-IREA)

Food security is one of the most challenging tasks in the world. Italy produces most of the consumed rice in Europe within its northern territories, along with other European-Mediterranean countries such as Spain and Greece, most of the rice production is in this region. European Union decided to run a project under Horizon2020 program to support agricultural studies related to food security. As the result ERMES project was started to develop a downstream service based platform dedicated to rice farming systems based on Earth Observation (EO) products and in-situ data within crop modeling solutions. ERMES was launched to deliver two services, 1) The Regional Rice Service (RRS) intended to provide public authorities in charge of regional planning with a customized agro-monitoring system devoted to monitoring of crop status, analysis of regional yield estimates and alerting on potential biotic and abiotic risks. 2) The Local Rice Service (LRS) provides the private sector (farmers or agro-services and insurance companies) with information on yield variability at farm scale. Spatially distributed assessment in form of High Resolution (HR) maps related to Cultivated area, Yield variability pattern, Risk alert (biotic/abiotic) and Crop damage are disseminated to final End-User via smart technology applications.

Bio: Ramin Azar is a GIS and Remote Sensing research consultant. He obtained his PhD in remote Sensing from Politecnico di Milano, Italy and his Msc in GIS & Remote Sensing from UPM, Kuala Lumpur, Malaysia.

Topic: Big Data and Big GeoData: You Can�t Have One Without the Other

Speaker: Bill Johnstone, Spatial Vision Group

Big Data is a trendy topic. Key terms we hear when people talk about Big Data include: �the three V�s�, analytics, business intelligence, artificial intelligence, social media and social networks, sensor webs, the Internet of Things (IOT), smart cities, smart infrastructure, high-performance computing, network databases, cloud-based technology stacks, and cool FOSS Python / JavaScript data analysis and visualization libraries (�wow!�). In this space, we encounter terms such as: structured-, semi- and unstructured data; data lakes, data warehouses and data marts; and Zetta-, Yotta- and BrontoBytes.

Big GeoData is intimately-related to Big Data. Some would argue that most Big Data applications must include Big GeoData in order to be useful. Related but important topics from within our own geospatial world include: Open Data, data catalogs, data discovery, Extract-Transform-Load (ETL), geoanalytics, Building Information Modelling (BIM), multi-Levels of Detail (LOD) GIS databases, CityGML, LiDAR, modern-day remote sensing data flows (new satellites and drones), spatial cloud services, and RESTful interfaces. The geodata streams and storage requirements we are starting to see in our own day-to-day work are daunting. Even with these challenges, Big Data and Big GeoData together offer significant benefits to the private and government sectors.

This talk will discuss selected terms and concepts from these two areas. We will explore who the current players and technology vendors are, how the datasets and technologies are being used today (including a simple IOT-transit example from the Lower Mainland), and what the future might hold for Big GeoData.

Bio: Bill Johnstone, Ph.D., P.Eng., is a Principal Consultant and founding partner of Spatial Vision Group Inc.

Topic: International Geospatial Harmonization of Sister Datasets (Hydrography and Watershed Boundaries) between Canada and the U.S.A.

Speaker: Judy Kwan, Environment and Climate Change Canada

Water knows no political boundaries. The Boundary Waters Treat of 1909 established the International Joint Commission(IJC or the Commission) and committed Canada and the United States to cooperatively address shared water concerns. The IJC-International Watersheds Initiative is currently leading an effort to �harmonize� hydrographic datasets along the Canada-USA border. The IJC, through its Transboundary Data Harmonization Task Force is working to help implement a new paradigm for all shared Canada-U.S. basins by establishing both �harmonization� data and processes. In the shared waters between the two nations of Canada and the U.S.A.(called the �Swath�), this geography equates to 232 bains, >1574 watersheds, >8793 sub-watersheds, and for each one of these shared basins, a series of �harmonization� steps are completed to ensure that water users on both sides of the international border have the best available harmonized hydro data geospatially available for them. This presentation will discuss this highly coordinated effort, the Task Force, the methods and processes, and a status for all binational basins.

Topic: Capturing reliable changes in unreliable historical data

Speaker: Ilana Klinghoffer, Northwest Hydraulic Consultants

How do you analyze historical data of varying quality? I will discuss this problem using a case study of bed elevation changes in the Fraser River. While there is considerable historical bed elevation data for the Fraser River, the quality of this data varies over time and space. Working with this data is challenging because it is collected using different technologies over time and not sampled uniformly with respect to space. One approach I found useful was to capture the uncertainty in bed elevation changes dynamically and spatially. Specifically, I made use of fuzzy inference logic integrated in GIS through a Geomorphic Change Detection model. The resulting maps can help visualize uncertainty in spatial and temporal changes and I show how they can be used to help separate �real� and robust changes from seemingly apparent but unreliable ones.

Bio: Ilana Klinghoffer is a junior geomorphologist at Northwest Hydraulic Consultants where she frequently uses GIS in projects including flood hazard assessments, erosion and slope stability assessments, hydropower projects, and stream restoration projects.

Topic: The Art and Science of Habitat Suitability Modelling � Occurrences, Physiology and Demography

Speaker: Matthew Bayly, MSc Student, UBC Department of Botany

Spatial habitat modelling is a hot and actively developing field. Broad scale habitat suitability models are predominantly constructed with species� occurrence records (surveyed presence/absence data), but assessing the accuracy of these models is a major challenge. Here, I construct alternative models using physiological and demographic data. I compare multiple approaches using the scarlet monkeyflower as a case study system. Major discrepancies identified between competing methods were alarming. Occurrence records can be misleading. A species� spatial distribution is not always a perfect reflection of its optimal habitat.

Topic: Analyzing Space-borne Synthetic Aperture RADAR

Speaker: Olivier Tsui, Hatfield

Given its size and remoteness, harsh climate, and limited infrastructure, environmental baseline data describing most Canadian northern regions are limited. This is particularly evident for water resources, which can impede effective environmental planning, assessment, and monitoring. In the Northwest Territories, the vast number of freshwater lakes in the North Slave and Central Mackenzie Valley require effective and cost-efficient methods to monitor changes in ice cover and status across large areas.

Hatfield through funding from the Canadian Space Agency (CSA), has developed an innovative way to analyze space-borne synthetic aperture radar (SAR) data to provide indirect information on ice thickness and water depth through the detection and delineation of bottom-fast ice or grounded-ice. This presentation provides an overview of the "Using RADARSAT-2 Data for Cumulative Impact Monitoring for Water Resources in the Northwest Territories (EO-CIMP)" project.

Bio: Olivier Tsui was born in France and grew up in Montreal, QC. He moved to Vancouver in 2001 where he graduated from the BCIT GIS ADP and obtained his graduate degree from UBC. He has worked at MDA Geospatial Services (formerly RADARSAT International), CH2M Hill, and Hatfield Consultants. At Hatfield he is a Senior Geomatics Specialist specializing in mapping projects that use satellite and aerial remote sensing data for various environmental applications.

Topic: Automated Motion Imagery Exploitation for Airborne Intelligence, Surveillance & Reconnaissance

Speaker: Dr. Stephen Se

Airborne surveillance and reconnaissance are essential for many military missions. Such capabilities are critical for troop and civilian protection by providing enhanced situational awareness. Motion imagery gathered from both manned and unmanned airborne platforms provides surveillance and reconnaissance information for analysis, but these sensors can gather very large amounts of video data. It is extremely labour-intensive for operators to analyze hours of collected data without the aid of automated tools.

At MDA, we have developed a suite of automated video exploitation tools that automate the processing of airborne video for mosaicking, change detection and 3D reconstruction, within a GIS framework. The mosaicking tool produces a geo-referenced 2D map from the video frames. The change detection tool identifies differences between two repeat-pass videos taken of the same area of interest. The 3D reconstruction tool creates geo-referenced photo-realistic 3D models. The integration with a GIS environment allows easy access to other GIS tools and facilitates cross-referencing to related analysis.

Bio: Dr. Stephen Se is with the Research and Development group at MDA where he leads computer vision R&D projects to develop systems for defence applications. He completed a B.Eng. degree with first class honours in Computing at Imperial College, London and a Ph.D. degree in the Robotics Research Group at University of Oxford. He then worked as a post-doctoral researcher at the Department of Computer Science at University of British Columbia on vision-based mobile robot localization. His research interests include computer vision, video processing, 3D modeling and mobile robotics. He is a registered professional engineer and a senior member of IEEE.

Topic: Using Mobile Technology to Measure People, Analysing the Data Using Emerging GIS Web App Tools

Speaker: Bill Johnstone, Ph.D., P.Eng., Principal Consultant, Spatial Vision Group Inc.

With the advent of mobile data and communications, GPS in cell phones, Free and Open Source Software (FOSS), Open GIS Data, Open Street Map, web-cloud / Software As A Service (SAAS)... the GIS and geomatics markets are going through yet another transformation and expansion. New services are being offered to existing GIS markets and new sectors are opening up.

In this session we will explore two themes from this space:

  1. Measuring people using mobile technology, and
  2. Compiling/Analysing/Publishing this data using SAAS GIS-WebApps.

Specific topics include:

  1. Measuring People Using Mobile Technology:
    • Established & emerging:
    • Outdoors / field measurement products (natural resource, utilities)
    • Indoor measurement products
    • Smartphone activity trackers (e.g., Open GPS Tracker, Google My Tracks, ESRI Collector, FitBit, Strava)
    • Which behaviours can we measure? Commuting, Shopping, Evacuating from extreme hazards...?
    • Bluetooth integration to gather heart rate, blood pressure, blood chemistry
  2. Established and Emerging GIS-Web-App Tools:
    • Google Maps, Google Map Engine (now deprecated), Google Maps API
    • ArcGIS Online
    • GeoBC iMap, Latitude Geocortex
    • CartoDB, MapBox, Leaflet

This session builds on ideas and issues discussed in recent VGUG talks (e.g., DNV's GeoWeb). We can ask:

  • what is VGUG's collective sense of the current state of web GIS,?
  • who are the key suppliers to watch?
  • what are the emerging opportunities?
  • how good are the current toolsets?

Approach for the Session: Rather than our usual "talk followed by questions" format, we will facilitate an open discussion on these two topics. Bill will present materials and examples that he has gathered to provide some background for the discussion.

Please bring along your own ideas of interesting people-measurement and web-GIS products and tools that you have been working or experimenting with. Similar to our Feb 2014 brainstorming session, we will compile everyone's input and publish a summary in PDF form.

Topic: Data Driven 3D City Modelling

Speaker: Dan Campbell, Graphics Planner at City of Vancouver

3D visualization has become a standard component in all planning and development work. As software has matured, 3D work is moving from an area of complexity and high expertise to a generalized task well within the skill set of most staff. A fundamental component driving this change is a shift from city models being modeled by hand to using existing corporate GIS data, be it zoning boundaries, urban forest coverage or sewer lines to generate the buildings and other geometry on the fly. City models are no longer just pretty looking geometry, but an intelligent environment to conduct analysis and develop what if scenarios. This new approach is substantially decreasing the amount of time needed to create a functional, and intelligent, model, as well as expanding the scope, and scale, of what can be modeled. With this move to intelligent 3d city models, the boundaries defining 3D, BIM and GIS are blurring.

Another change occurring is how the model is used. The model is no longer restricted to being only a tool used for internal review and analysis, but is becoming a resource for public communication and involvement. Rather than creating display boards or PowerPoint presentation, the model itself is being taken out to public meetings where residents can see exactly how changes in their neighbourhood will look, and interactively examine what the impacts will be.

Bio: Dan Campbell is a Systems Analyst with the city of Vancouver, responsible for coordinating 3D visualization and analysis activities, and managing the city of Vancouver 3D model. He has a background in fine art, planning, and urban design which he is able to apply in the context of GIS, and city modeling. Dan has spoken at many conferences including Autodesk University, Map Asia, GeoWeb, GeoTec, URISA, BIM Forum, Middle East Geospatial Forum, India Geospatial Forum and the Pitney Bowes Insight focusing on the role of 3D as it relates to design and public involvement. Dan has had articles published by Vector1 Media, GeoWorld, and Geospatial World. Dan is a member of the Institute for BIM in Canada's Technical Advisory Committee. In 2012, Dan was the recipient of the Pitney Bowes Meridian Award for Technical Achievement.

Topic: Disaster Risk Modeling; bridging the gap between knowledge and action

Speaker: Murray Journeay, Research Scientist, Earth Sciences Sector, NRCan

As communities continue to grow and develop in areas exposed to natural hazards, so too does the potential for increasingly severe and devastating events like those recently witnessed in Japan, New Zealand and Chile. Lessons learned from these disasters underscore the need for a comprehensive risk-based approach to land use planning and emergency management at all levels of government - one that utilizes geospatial knowledge about the risk environment to inform actions that can be taken on the ground to reduce the vulnerabilities of people and critical assets and to increase disaster resilience over time. This talk will focus on GIS-based methods of disaster risk modeling that are being developed in Canada to assist communities in analyzing the socioeconomic consequences of earthquakes and floods, and in evaluating the effectiveness of mitigation alternatives. We will explore the capabilities of community-based risk assessment methods in the context of two case studies from southwestern British Columbia.

Bio: Murray Journeay was born and raised in the deserts of Arizona and currently makes his home in southwest British Columbia where he works as a research scientist with the Earth Sciences Sector of Natural Resources Canada. For the past 10 years, Murray has been actively involved in research aimed at developing methods of integrated risk assessment and scenario modeling to promote the uptake and use of earth science knowledge in support of planning, policy development and decision-making. Domains of interest include disaster risk reduction, groundwater resource management and participatory place-based planning.

Time: 5:30 pm

Topic: The 'Bad Data' Problem

Speaker: Marc Thorup

The 'bad data' problem is nothing new. The talk is meant to enable discussion on evolving best practices for the future of data collection and management. This relates to many industries, but a scientific frame will be used to re-illustrate the dilemma. This will involve a case study that contrasts lichen species' health as an indicator for local air quality. Ideally with good data and a quality air circulation model, GIS can interpolate an air quality index for the area. This can be further detailed with more expertise in the air circulation model (e.g. AERMOD considers meteorological and anthropogenic constructs beyond the aerothermodynamic equations).

The talk is meant to address:

    Access to existing data and problems with its use;
    the reality of trying to adapt data collection standards; and
    what collection strategy changes might be feasible to capitalize on modern technology.

Bio: With a background in Environmental Science and Biology, Marc completed the ADp-GIS program at BCIT. He has combined his skills this past year working in a multidisciplinary capacity for G3 Consulting Ltd.

He is also the Secretary of the Executive for the West End Community Centre and - through WECC - he is preparing a computing skills workshop. The program considers age, language, skill level and social ability as it teaches GIS/CADD processes, database administration and basic programming. Marc speaks English and French and has a working knowledge of Spanish and Mandarin - these languages have proven helpful in making community development more accessible.

Topic: Open Source GIS: It's better than you think.

Speaker: Casey Vandenberg, GIS Specialist, SJ Geophysics Ltd.

As Geographic Information Systems become increasingly mainstream, software development appears to be shifting from a closed source model to an open source or hybrid model. Increased adoption and acceptance of GIS as a discipline has also led to a proliferation of desktop and web based GIS applications. This talk will focus on several of these open source GIS and visualization packages (e.g. GRASS, QGIS, Paraview) to illustrate how Open Source GIS no longer means command line terminals in a Linux environment, but clean, easy to use UI's that are accessible to even the most novice user. A variety of GIS applications will also be presented to help highlight the quality of these tools. Special attention will be placed on their use in the Geophysics industry.

Bio: Casey Vandenberg has been a GIS specialist with SJ Geophysics Ltd. for the past five years.

Topic: Implementing a Gas Distribution Risk Model using Smallworld GeoSpatial Analysis for Pipe Replacement Programs

Speaker: Piet Nooij, Production Process Manager Business & IT Services, FORTISBC

FortisBC is a gas distribution company in British Columbia with approximately 950,000 customers and has implemented a risk model for pipe replacements using Smallworld GeoSpatial Analysis. The risk model is driven by data in FortisBC’s Smallworld VMDS and a spreadsheet containing risk values for object attributes. The risk model calculates a relative risk score for every pipe segment and thematically maps the distribution mains according to the level of risk. These maps can then be overlaid with municipal infrastructure projects, pavement plans, and FortisBC’s own system improvements. Mains that show a higher risk are further evaluated for replacement at the same time. This presentation will discuss the development of the risk model, the implementation in GSA, the business benefits, and lessons learned:

Learning Objectives:

  1. How FortisBC implemented a Risk Model with GE’s GSA application in a relative short time frame.
  2. How the risk model aided to prioritize and categorize distribution pipes with a probability of failure for long and short term replacement
  3. Which business benefits were delivered by the Risk Model and GSA application

Topic: The application of remote sensing data to support climate change adaptation decision-making

Speaker: Taylor Davis, LiDAR Applications Specialist, Terra Remote Sensing Inc.

Climate change is a �hot� topic these days. It tends to invoke strong and often diverging views on whether climate change is going to happen (to what extent and when), is happening, should be mitigated, should be ignored, or has to be adapted to. The essential question that should be answered is: how can we strategically place investments in our communities that mitigate future risks, increase community resiliency and address the uncertainties of climate change at the same time? Answering this question requires mapping out adaptation strategies that have benefits to our communities - irrespective of future climates. Justifying the investment decisions of today against the potential risks of tomorrow is a complex undertaking.

These investment decisions have to be based on the best information possible, and can to a degree be supported by up-to-date geospatial information. Cutting-edge remote sensing techniques including LiDAR, and Hyperspectral imagery yield multiple data sets capable of providing decision makers with comprehensive information regarding the health, species and physical characteristics of vegetation, abundance and type of impervious surfaces, floodplain characteristics, and assessments of our as-built infrastructure.

My talk will generally focus on the application of remote sensing data to support climate change adaptation decision-making. As the Insurance Bureau of Canada recently identified urban flooding as the highest natural disaster insurance cost in Canada, there will be a specific focus on rainwater management.

Speaker: Ann Stark, GIS Analyst, City of Bellingham, Washington; President of the Washington Regional chapter of URISA; Co-host NW WA GIS Users Group

The Island County Marine Resource Committee (MRC) has collected a variety of nearshore, geospatially-referenced data on forage fish, feeder bluffs, eelgrass and more. These, along with data collected by natural resources agencies, reside in many separate, isolated locations, largely unknown to the public, scientists, and planners at all levels to whom they might be helpful in making decisions.

In a collaborative venture toward improving archival of and access to these data, the MRC, with support from the Northwest Straits Commission, partnered with the City of Bellingham, Washington to create SoundIQ, an adaptation of the land-based Bellingham data portal called CityIQ. The result is a web-based Ecosystem Tool designed to consolidate disparate data, provide interactive mapping, and to produce data summaries of Island County's nearshore data. SoundIQ runs on ESRI�s ArcServer technology.

Previously unprecedented, a user can click on a map location and generate a report summarizing ecological studies done, have photos and descriptions of public beach access points, and have links to online scientific documents about the area of interest.

SoundIQ is a compilation of publicly available data layers developed by the Island County MRC, Puget Sound Nearshore Restoration Project, Washington State Department of Health, National Oceanic and Atmospheric Administration, Washington Department of Fish and Wildlife, Washington Department of Natural Resources, and the United States Agriculture Department. Assistance with data acquisition was also provided by ESA Adolphson and by the Island County Planning, Public Works, and Health Departments.

Topic: Extending ArcGIS Desktop for Fish Habitat Identification Using Digital Elevation Models (DEMs)

Speaker: Frank Poulsen, Systems Analyst - ESSA Technologies Ltd.

raditional techniques for understanding aquatic habitat in streams have focused on manual measurement of instream conditions. Such techniques are labour intensive and often costly to perform over the spatial and temporal scales utilized by aquatic species. New remote sensing techniques, such as airborne water-penetrating Light Detection and Ranging (LiDAR) and boat-mounted acoustic sensors can produce highly accurate Digital Elevation Models (DEMs) with continuous coverage of long segments of channels and stream networks. Thus, we now have the ability to describe the same aquatic habitats, using automated techniques, continuously over long sections of river channel.

ESSA is collaborating with the US Forest Service to develop a free suite of ArcGIS Desktop tools for processing DEMs repeatably, reliably and at a low cost. The goal is to facilitate the characterization of aquatic habitat and floodplain geomorphology to support aquatic habitat analysis.

ESSA will present the tools developed to date, including the automated layout of cross sections, Thalwegs and bankfull elevations. I will also describe the method for detrending the DEM to remove the overall river valley slope and how this can be useful for rapid identification of flooding events and assessing off-channel habitat. Finally, the story of how we developed a methodology for creating a centerline from the stream banks will be used to illustrate our problem solving approach. Future enhancement includes exporting cross-sections to hydrological models (HEC-RAS and possibly MIKE11) as well as outlining potential habitat such as pool-riffle sections.

Bio: Frank�s specialty is combining environmental knowledge with strong technical skills. He commonly uses ArcObjects to make ArcGIS solve tasks, that it is not possible to do out-of-the-box, by developing extensions and geoprocessing tools. Working at ESSA Frank developed a GIS model together with biologists to analyze the potential impact on available habitat from climate change on two species of concern for the Cariboo-Chilcotin area in BC. He is also involved in developing GIS tools for predicting stream habitat potential from LiDAR generated Digital Elevation Model (DEM) data for the US Forest Service. He earned his Master of Science degree in Engineering at the Technical University of Denmark, where he split his course work between environmental and computer science.

Topic: Using GIS to Model Wildfire Risk

Speaker: Claire Tweeddale, B.Sc., Dipl T (GIS), P.Geo, GIS Analyst, Forest Ecosystem Solutions Ltd.

This past summer in BC 3090 fires consumed more than 200,000 ha (source: BC Forest Service website http://bcwildfire.ca). GIS can be used to predict areas at high risk of fire so that mitigation strategies such as brush clearing or other treatments can be done before a fire starts.

This presentation introduced three different GIS models that can be used to predict wildfire risk: condition class calculation, spotting algorithm and the Wildfire Risk Management System (WRMS). Condition class is useful on a broader scale to estimate fuel loading. The spotting algorithm considers wind speed and direction to determine urban interface areas at risk. Finally, the WRMS model determines overall risk by calculating the probability and consequence of a fire. For each model, the input data and methodology will be discussed, as well as examples of where they have been used.

Bio: Claire Tweeddale obtained her undergrad at UBC in Physical Geography, and 6 years later completed the GIS program at BCIT. Since 2002 Claire has been working at Forest Ecosystem Solutions Ltd (FESL). FESL is a small consulting company located in North Vancouver that provides analytical services for resource industries (forestry and oil and gas), Government, and First Nations clients. At FESL Claire has been involved in many GIS analysis projects, including Ecosystem Representation Analysis for Quesnel and Prince George TSA, fire condition class mapping for the southern interior, and fire probability mapping for the whole province. She has also developed GIS tools such as the Wildfire Risk Management System (WRMS) dynamic model, and the Pumping Limit Model. Outside of work, Claire enjoys playing soccer, hiking, and cheering for the Canucks.

Topic: A Conceptual Approach to Dynamic Sedimentary Basin Modelling using the Point Moment Method: the London Clay Formation Case Study.

Speaker: Sarah Elizabeth Pearce, M.Sc.

The subsurface modelling of urbanized dynamic sedimentary basins is important to inform structural planning. A generalized approach called the Point Moment Method is presented to more effectively characterize floodplain clay soils. Progress on the problem of modelling 4D geoscientific data sets is achieved by the integration of borehole data into a GIS. An iterative method that incorporates historic geomorphologic data, microfossil data, hydrology and expert scientific input drawn across disciplines is developed. The inclusion of temporal elements allows for the modelling of dynamic erosional subsurface environments to be better understood. X,Y,Z elevation data are modelled as vector points to which numerous attributes are attached; natural neighbour interpolation is used to generate subsurface digital elevation models. The Point Moment Method is applied to a case study of the London Clay Formation (LCF) with initial results revealing regional geospatial variation in the formation thickness and; at one study site, the spatial distribution of existing hollows which are the remnants of open-system pingos.

Bios: Sarah Pearce was born and raised in Vancouver, British Columbia where she graduated from Kitsilano Secondary school�s early French immersion program, Langara College�s Environmental studies diploma program, and proceeded to spend a year working as a junior project scientist in a biochemistry lab within a environmental consulting firm. She moved to Victoria, BC in 2002 where she frequented the University of Victoria�s Geography pedology and geospatial laboratories until she graduated with a Bachelors of Science in Geography with distinction; where her directed study, involving GPS,GIS and historic black and white and recent digital aerial photography, was entitled: Salt Marsh Habitat Assessment and Restoration Strategy in the Gorge Waterway and Portage Inlet.

After undergrad, wildfire hazard modelling and GIS map generation became a summer field position which extended many years to include the generation of numerous wildfire hazard maps for urban and rural regions of BC. Sarah Pearce was then accepted into University College London`s Remote Sensing Masters of Science program, where she lived in central London, England during most of 2008, where she completed her MSc thesis entitled: A Conceptual Approach to Dynamic Sedimentary Basin Modelling using the Point Moment Method: the London Clay Formation Case Study.

Sarah Pearce now lives on the Sunshine Coast, BC and is currently working on a remote sensing contract involving satellite imagery with the Arctic Sea Ice / People of a Feather project which is an education and outreach initiative that combines Inuit, scientific and film making approaches to document sea ice ecosystems.

Topic: Timber Supply Analysis

Speaker: Rueben Schulz, Dipl. T. (GIS), M.Sc., FIT, Resource Analyst, Forest Ecosystem Solutions Ltd.

Timber supply analysis is a component of the legally mandated timber supply review (TSR) process in BC. It begins with a classification of the land base (subject to tenure, vegetation type, and management goals) to determine areas available for harvesting. Estimated tree volumes, combined with the modelling of future growth and harvesting allow for a sustainable harvest level to be defined and the dynamics of the forest resources to be explored. The goal is to capture current management and knowledge about an area.

One of the outputs from timber supply analysis is the possible state (age class, tree species, and pattern) of the forest over time, which forms the basis for additional analysis such as: carbon capture, wildlife habitat, or silviculture opportunities. It also provides an opportunity to ask "what if" questions such as what happens to the available timber if the mountain pine beetle kills all the pine.

This talk will give an overview of the steps undertaken in a timber supply analysis and cover the wide range of data and assumptions used and describe where they fit into the analysis. A brief mention of how GIS supports analysis and data collection will be made.

Bios: Rueben Schulz completed a Bachelor of Science in Forestry and a Masters of Science at UBC, and survived the GIS program at BCIT. He has been working as a resource analyst, GIS analyst, and programmer for Forest Ecosystem Solutions Ltd. (FESL) for the last three years. FESL is a small consulting company located in North Vancouver that provides analytical services for resource industries (forestry and oil and gas), government, and first nations clients. At FESL Rueben has worked on analysis of the Prince George TSA, Esketemc Community Forest (Williams Lake), and helped program a new version of the Wildfire Risk Management System (WRMS). Before moving to North Vancouver to work at FESL Rueben spent time running around the Chilcotin measuring trees. Years ago he contributed map projection code to the open source Geotools library and one day hopes to find time to get involved in more open source GIS programming.

Topic: Lessons Learned in Implementing GIS in Developing Countries

Speakers: Karl Kliparchuk, McElhanney Consulting Services Ltd., Irene Hwang, private consultant

In 2008, we implemented some phases of a previous user needs and data analysis for a mining company in Indonesia. The mining company uses ArcGIS, but was not being used in an optimal way. In the implementation, data from different departments and different formats were converted into a set of geodatabases. Training was provided to users at the remote mine site and in the head office in Jakarta. Technical issues, which are taken for granted in North America, can cause major problems in a developing country. We will review what was accomplished, the kinds of technical issues which you can encounter, and some ideas for best practices in this type of situation.

Bios: Irene Hwang has a B.Sc degree in Physics from the University of British Columbia and an Advance Diploma in Geographic Information Systems (GIS) from the British Columbia Institute of Technology (BCIT). Irene has over 10 years of experience in GIS software development and implementation. She is currently working as a GIS Senior Consultant.

Topic: The Glory and Disappointment of GIS Research

Speaker: Tom Poiker

An academic has a ten-percent chance of being remembered for what she would like to be remembered for and this presentation will show in graphic terms how this works with the author's example. I present two cases of my own research, one of which was celebrated beyond its merit and the other which got its due recognition but without any fanfare.

The Douglas-Peucker algorithm (Douglas and Peucker, 1973) is a nifty idea for line simplification and is in widespread use in the profession but, with a 50-line program, it does not deserve the type of attention that it got, all the way to articles even in 2008. The presentation gives a short overview of the technique, goes through its history and mentions some professor-student relations.

The Triangulated Irregular Network (TIN) is a data structure for the storing of surface data that fundamentally changed the digital description of terrain. The paper goes through the arguments that were put forward to convince different groups (myself, granting agency, students, etc) of the value of the research.

The talk is not so much about GIS as it is about aspects of an academic life and what one can learn from it. It is a story and should not be mistaken as a scholarly paper. However, the first part IS a story about a scholarly paper and how academic work can have an afterlife.

Tom Poiker's Bio: Early years in Austria and Germany. PhD (economic geography) from U. of Heidelberg, 1966. 1967 � today: Simon Fraser University (Geography and Computing Science) with short periods at other universities in the United States, Australia, New Zealand, Austria and Germany.

Started with GIS in 1967 in research and teaching. Known for TIN (Triangulated Irregular Networks), the Douglas/Peucker algorithm and a few other developments. Wrote some lasting papers and the first text in GIS. In 1997, started UniGIS, an online program (12 courses, two years). Retired since 2006. Changed spelling of name (from Peucker to Poiker) in 1979.

Topic: The Old "Ball and Chain"

Speaker: Dan Shannon, Engineering Manager, TELUS Network Operations

Utilities and Local Governments were early adopters of GIS technology. Early deployments were expensive and difficult to deploy. As a result, many implementations were successful largely because they clearly defined and limited what would be managed, and how it would be represented. Modern geospatial applications need not be constrained to choosing between form and content. However many, if not most, enterprise geospatial systems in service today carry with them limitations they inherited from their initial design from years ago.

What are the challenges that early adopters of GIS are facing as they attempt to take advantage of newer capabilities? What has improved, and what has not?

Bio:

Dan Joined TELUS (BC Tel at the time) in 1981. He is currently responsible for the development and use of systems and tools supporting Outside Plant Planning and Engineering at TELUS.

Topic: Map-Making 101: Or, "How to take an idea for a walk"

Speaker: Jeff Clark, lead map-maker, principal at CGC and founding partner at Spatial Vision Group

Is the Internet going to kill the traditional map? Most people in GIS circles are familiar with the question as it has been asked regularly for the last decade. So, what's the answer? If anything, the field of cartography has died while the practice of map-making is truly alive.

What's the difference between cartography and map-making? The answer lies in the definitions.

This presentation provides a proper burial for the field of cartography and a send-off for the practice of map-making. As part of the send-off, a discussion of current map-making techniques will be presented. These are some of the techniques used to create the innovative (at least by Canadian standards) Bivouac Backcountry Series: Garibaldi Park topo map - a detailed 1:50,000 scale map of the glacier-filled Garibaldi Park of British Columbia.

Topic: A GIS for Prospect Management

Speaker: Jim O'Leary, Tech Earth Services

How would you manage a group of tracts that have multiple owners and are available for various forms of exploration over given periods of time? Your solution must account for:

  • Many-to-many relationships between contracts and tracts.
  • Maps that show different views of tracts for the same area of land.
  • Documents that are associated with a given contract for a given map.
  • Reports that are associated with all contracts for a given map.
  • Permissions for users to view certain maps in certain areas.

Sound confusing? Sounds like a job for MapGuide!

In this month-s meeting, Jim O-Leary demos an application that he created for an oil, gas, and mineral management firm in Louisiana. The application is written in PHP and JavaScript and uses the MapGuide Enterprise APIs as well as a free DHTML package called TafelTree.

Speaker: Tamsin Lyle, M.Eng MRM P.Eng, Project Engineer Northwest Hydraulic Consultants

A significant proportion of Lower Fraser Valley lies within the Fraser River floodplain, and traditionally the houses, farms and people living on the floodplain have been protected by diking and other flood adjustments. It is therefore very important that governments and other policy makers have good information regarding water levels that would occur during a large flood event. In 2005, the Fraser Basin Council retained Northwest Hydraulic Consultants (nhc) to develop a one-dimensional hydraulic model of the lower Fraser River, British Columbia. The overall objective of the project was to generate an up-to-date design flood profile based on both freshet and tidal flood scenarios - the last profile was completed in 1969, since which there has been significant development in the valley. The model extends from the ocean to Mission, a distance of over 100 km, and includes numerous side channels and branches, and inflows from five tributaries. Over 30 hydraulic structures - bridges, weirs and diversion structures - are included in the model.

The model was developed using both LiDAR and bathymetric data that were combined in a GIS database. In-house software was used to transfer the data into the hydraulic model. The model was calibrated and validated using an extensive network of gauges along the length of the lower Fraser. A multitude of scenarios was examined using the model to aid in long-term and short-term planning for flood protection in the Fraser Valley. GIS was used to present model results. One of the outcomes of the report was the discovery that none of the dikes from Richmond to Agassiz are adequate to protect against a flood of record. These results have recently been presented to local governments, resulting in calls to update floodplain policy and to raise the dikes.

Speaker: William Johnstone, P.Eng., M.A.Sc., is a Principal Consultant and founding partner of Spatial Vision Group Inc.

The presentation will provide a look at an ongoing emergency preparedness study. The project was undertaken to assess the impact of tsunami on communities on Western Vancouver Island. Using Ucluelet as an example, the project will develop and assess mitigation and evacuation scenarios. It will also review the effectiveness of conventional cartographic and advanced visualization techniques in communicating consequences, risks and mitigation strategies. The presentation will present the seismic hazard characterization, development of a virtual community model, and creation of loss and evacuation scenarios. Using remote sensing, GIS, and numerical wave propagation and wave run-up models, the study is developing tsunami event scenarios for two earthquakes (a model of the Cascadia Subduction Zone (CSZ) earthquake that occurred in January 1700, and a model of a circa-2007 Cascadia earthquake). Together, the models cover a useful hazard spectrum of interest to Vancouver Island emergency planners. Given the rapid onset of the Cascadian event, public awareness and emergency preparedness are paramount.

This research is supported by PEP-BC (Provincial Emergency Program), NSERC-GEOIDE (Geomatics for Informed Decisions), the BC Integrated Land Management Bureau, the Canadian Hydrographic Service (CHS), the District of Ucluelet, and Spatial Vision Group, Inc. Project participations include UBC Civil Engineering, SFU Department of Geography, and University of Washington Department of Applied Mathematics.

Topic: The Use of Geomatics Technology in Coastal Research

Speaker: Doug Hrynyk, Parks Canada Agency, Western and Northern Service Centre

The issues arising from the establishment and operation of a National Marine Conservation Area are myriad. A GIS supporting the establishment and eventual operation of an NMCA must capture a broad range of data.

Moving from the land into the sea, these include: jurisdictions, cadastre, zoning, facilities, a comprehensive representation of stakeholder uses, aboriginal concerns, cultural heritage, oceanography, geology, ecosystems, significant flora and fauna, as well as fisheries. This presentation will offer an overview of the types of data available; the difficulties in filling gaps in those data in a marine environment; challenges that arise when one enters the marine environment; and some of the tools that can be used to generate possible solutions from the GIS.

Topic: Web Mapping Technologies

Speaker: Jim O'Leary is a developer, technical writer, and programming instructor.

This month's presentation looks at several recent technologies that allow mapping via the Internet:

  • MapGuide Open Source is a mapping program that Autodesk has released to the Open Source community. There is a tremendous opportunity for organizations to develop this offering.
  • Oracle Spatial allows storage of geographic objects in a relational database and operations on these objects through geographic SQL.
  • Google Earth allows your program to fly over the earth, land at a specific location, and highlight geographic objects. Google Earth raises the bar for mapping programs.
  • Keyhole Markup Language (KML) is the XML-based language that controls Google Earth.
  • PHP is the "language that binds them all". PHP can connect to an Oracle Spatial database and dynamically generate KML based on a query. The MapGuide API is also written in PHP.

In the past geotechnical engineers and geoscientists have used a purely deterministic approach to evaluating geo-hazards. The investigation would typically involve manual air photo interpretation to identify potential sites of interest after which field teams would go to these sites and evaluate them for their risk to life and property. This approach can be very costly, especially if you are evaluating hundreds of kilometers of gas pipeline in the Andes, for example. Often times there is insufficient air photo coverage creating a need for an extensive data acquisition program which can start the project off with costs in the hundreds of thousands of dollars range.

In recent years GIS has been introduced to narrow this focus prior to acquiring this more expensive data or sending field crews out. With recent advances in the availability of higher resolution data such as the Shuttle Radar Terrain Mission data and global Landsat ETM+ imagery, scientists can start with a more probabilistic approach to geo-risk and hazard. GIS can be used to evaluate a number of data sets (factors) and produce probability maps which can be used to narrow the focus for choosing sites that require detailed investigation. GIS can also provide methods for quantifying some of these risk factors allowing the investigators to prioritize these sites.

Topic: GIS Certification Panel - Current State and Future Trends

Speakers: Karen Stewart, Tim Smith, William Johnstone

In recent years GIS certification has become a prominent and controversial topic of conversation among the members of the GIS community. With the establishment of the GIS Certification Institute by the Urban and Regional Information Association and the steady climb of its membership, more and more GIS professionals are spending the time and money to acquire and maintain certification. How will this move toward certification affect the GIS community? Does it make employment easier or harder to find? Will certification instill greater understanding and trust in the often complex work GIS professionals perform or is it just one more expense for the struggling contractor?

Topic: Satellite Imagery - Emerging Trends

Speaker: Tor Henderson

From the launch of LANDSAT satellites in the 70/80's to the emergence of the high resolution satellites in the 90's, we have witnessed a slow acceptance of satellite imaging technology in this time period. However, it is only within the last 5 years that the Earth Observation community has fully adopted satellite imaging technology, and has seen its expansion to non-traditional users resulting in a significant growth in satellite imagery sales. Recent past events such as 9/11 and the creation of Google Earth, as well as the Convenience Factor has bolstered the choice of satellite imagery over aerial imagery even despite the resolution tradeoff. This brief presentation will highlight the various trends in the industry by looking at the history of satellite imaging, the technological advancements and the sensor benefits.

Topic: Introduction to the Use of GIS for Epidemiological Studies

Speaker: Sunny Mak, GIS Analyst, BC Centre for Disease Control

The use of GIS and spatial analysis for epidemiological studies has experienced much growth and depth over the past five years. This is largely due to the increased availability of geographically indexed health and population data, advances in spatial statistical methodology, especially at the small area level, and availability of academic and commercial courses on GIS. However, associated with this powerful technology are two critical issues that need to be addressed: preserving patient confidentiality and ensuring data accuracy.

This introductory lecture will discuss how GIS and spatial analysis can be used for epidemiological studies. Data quality, confidentiality and map creation issues will also be discussed.

Biography: Sunny Mak is a GIS Analyst/Medical Geographer with the BC Centre for Disease Control. His research interests include GIS mapping, spatial analysis and modeling of infectious diseases. His current projects include surveillance and planning for the arrival of West Nile virus in BC, ecological niche modeling of Cryptococcus gattii on Vancouver Island and analysis of sexually transmitted diseases in the Vancouver Lower Mainland.

Topic: GIS Solutions to Infrastructure Asset Location Cross Referencing

Speaker: Gary St. Michel, P.Eng, President, St. Michel Consulting Inc.

Asset management requires integration of data across different asset types. Relating data across asset types requires locational cross referencing. A typical municipal agency has archived datasets stored on paper, microfilm, CAD drawings and legacy databases. This historical data is difficult to incorporate into an asset management system because the geographic location of the asset has been recorded in several different ways - street addresses, cadastral locations, lineal measurements, fixed link road segments, GPS and x, y coordinates, block descriptions or written descriptive comments. Because of the difficulties in relating geographic locations between the various referencing methods, agencies have struggled with relating data across different asset types for years. This paper will discuss the history of location referencing and expose some significant problems regarding both linear and spatial location referencing. It will also present a unique solution that allows an agency to make use of existing datasets to populate asset management systems reducing the need for expensive data re-collection.

Historically, linear asset data was stored in datasets using fixed length segments. These segments existed independent of one another and independent of location. Location was merely an attribute of each segment in much the way traffic volume is an attribute of a roadway. For example, a road�s name and its �from� location and �to� location, were just labels attached to the segment and were not inherent parts of the segment�s definition. Computers were unable to model the relationship and interaction between a segment and adjoining or overlapping segments. This problem was overcome, for linear assets such as roadways and pipes, through the introduction of linear referencing and dynamic segmentation introduced in some Infrastructure Management Systems (IMS) in the mid 1980�s. These techniques allowed computers to model the interaction between a roadway and for example the utilities beneath. Relating field condition data collection to the known linear asset inventory was also greatly simplified with advent of dynamic segmentation.

The introduction of GIS brought with it the ability to spatially reference any geographically fixed location asset and to begin to model the interrelationships between assets. GIS however is limited in its modeling capabilities. Specialized IMS software can do a much better job of modeling the performance of infrastructure assets than can be accomplished through existing GIS products. However, these IMS require access to the spatially referenced GIS asset data. Until now linking the IMS for linear assets to the location referencing relationships warehoused in the GIS, was a tedious process involving digitizing point, line segment element locations within the GIS and creating an element identification relationship between each GIS element and its related element in the IMS. In more recent years some GIS vendors have added linear referencing and dynamic segmentation capabilities to GIS making it a simple process to establish relationships between linear assets based systems such as pavement management systems and the GIS. Once this relationship is established, data from any infrastructure asset, linear or non-linear, can be passed to the IMS through the GIS interface and visa versa. The paper will outline this simplified technique for establishing the link between GIS and IMS.

Many infrastructure management practitioners believe that the linear referencing process has now been made obsolete with the advent of inexpensive and accurate GPS referencing. However, the authors have discovered significant, and so far in-soluble, problems with relying solely on GPS location referencing in conjunction with field data equipment. The problems include undetectable measurement inaccuracies and incomplete GPS coverage � it is difficult to measure GPS underground or in tunnels. The authors have also found systemic and undetectable measurement errors inherent in using linear referencing alone for field data collection. This paper will discuss these problems and present a technique developed by the authors to use a combination of both GPS and linear referencing to ensure accurate location referencing of field data.

The concepts put forward in this paper will be illustrated using examples where the GIS links and location referencing techniques have been used successfully in recent IMS implementations for several municipalities in North America.

  • Provides information about watershed management, stream ecology, fish and wildlife habitat and restoration opportunities and promotes active stewardship
  • Creates an open forum for discussing the use and management of natural resources; and
  • Promotes planning sustainable communities;

The Community Mapping Network is made up of a number of community groups, organizations and individuals that collect and map natural resource information. A steering committee is responsible for managing CMN that includes representatives from the BC Conservation Foundation, Fisheries and Oceans Canada, Canadian Wildlife Service, Ministry of Agriculture, Food and Fisheries, Fraser Valley Regional District, Greater Vancouver Regional District, local governments, and community groups.

Many sensitive habitats such as urban and smaller rural watercourses, eelgrass beds, riparian areas and wetlands remain unknown, poorly understood, and suffer from impacts of human development. Methods provided through CMN reflect a novel set of tools to explore and promote awareness of these habitats by mapping their location and inventorying their attributes. The awareness and commitment to local watercourses and other sensitive habitats is an important process created through co-operation of local communities, First Nations, municipalities, planners, and managers.

Maps and natural resource information are �web-served� to assist communities and local governments with landuse planning, promote conservation and protection of sensitive habitats and to raise awareness and respect for ecological values. Many types of information are provided through the CMN such as fish and wildlife distribution, streams and wetlands, eagles and herons, rare and endangered species, and possible restoration sites. Selected information and thematic maps are available at a scale of 1:5,000 for the Georgia Basin and Central Okanagan. Province-wide coverage is available for watercourses, fish distribution, coastal resources and other themes.

Topic: Rethinking, not retooling: modeling population health within a GIS environment

Speaker: Bell, Nathaniel. Researcher, Faculty of Health Sciences; Masters Candidate, Department of Geography, Simon Fraser University

Recent initiatives to strengthen social health in British Columbia are an opportunity to engage public health policy makers with GIScience and systems. Combining GIS and traditional methods of spatial analysis with growing public health concerns allows researchers to model salient questions in population health. One of the most fundamental methods of spatial analysis is multicriteria analysis (MCA). While the functions commonly associated with GIS and MCA are application specific, the integration of these tools in support of public health investigations is relatively new and unexplored. Population health based MCA is designed to take into consideration multiple objectives and decision criteria of an expert group for the purpose of addressing inequalities in health at the local level. Managing complex problems using expert knowledge based on a "yes," "no," "agree," or "moderately agree" response is often problematic as determining the range of values between responses is inherently fuzzy. Combining fuzzy set theory and MCA allows the model to measure uncertainty in the decision making process. This research investigates the use of a fuzzy set MCA in mapping the decision maker's preferences. The strength of this approach is providing public health researchers a flexible and standardized decision framework for assisting policy makers in determining levels of socioeconomic inequality at the population level.

Location. Location. Location. With so many maps and datums out there, how does a person know what datum is correct? How come my GPS coordinates don�t match up on my map? Why is there a shift of 100 metres? How do I transform between different datums? What is a datum? What is the EPSG? Why have ESRI and Oracle adopted them? Are there other transformation tools or libraries out there, besides Blue Marble�s? Does offshore or onshore make a difference? How come there are so many datums? These presentation looks to provide some answers to some of these questions and to point out that latitude and longitude are not absolute. Over the decades that surveyors have been trying to map the Earth, history and politics have shaped the way we see the world. Are the borders actually there? What if one nation adopts a standard, but the other does not? Does really matter what the co-ordinate system is? Why when I draw the a UTM Projection, the lines are curved, not in a grid? Is the OGC adopting these standards? Does it effect WMS?

Topic: Harnessing GIS for Ecosystem-based Socioeconomic Decision Making: a case study in marine reserve design in British Columbia. (Or, how to put that computer to work, until the motherboard begins to smoke�)

Speaker: Jeff Ardron, Marine Analyst, Living Oceans Society

In this talk, I would like to introduce some of the �leading edge� GIS tools being used in conservation design. But to do that, I would first ask that you cast your minds way back to the dark ages, sometime around the end of the previous century�

There, in the midst of the Land and Resource Management Plans (LRMP) throughout the province, dozens and dozens of maps of resources, wildlife values, and anything else the planners could think of, were all dutifully hung over the walls, tables, and any other available blank space� while participants would stroll from map to map, discussing nuances with colleagues, nodding sagely in conversation, sipping coffee, nibbling nibblies� all the time thinking to themselves, �I�m doomed; my job is toast; how am I going to keep track of all this stuff, let alone make a good decision... How can I figure all this out?�

I was at one of those LRMP processes (CCLRMP), and have been to others like them since. It was clear that the conservation sector had better get its GIS act together. (Living Oceans Society was the representative group for the marine conservation sector at the CCLRMP.) We realized needed to do two things:

  1. Start mapping the distribution of public resources in a fashion that reflected our philosophy of ecosystem-based management; and,
  2. Figure out some way to try to make sense of it all, so that we could put forward sensible recommendations.

I will spend a bit of time on the first point, but will mainly focus on the second point, considering the use of spatial optimization algorithms, particularly simulated annealing as used in the software Marxan. I�ll look at some of my original analysis work back in 2000-2001 for the Central Coast, as well as a revised marine analysis for most of BC performed in 2003 for the Coast Information Team. I will then briefly talk about on-going research, including the use of fuzzy inference in the mapping and interpretation of local ecological knowledge. And finally, toss out some thoughts and methodologies I have been exploring to reconcile resource use (such as fisheries) with conservation objectives of a sustainable ecosystem. All that in 30 or 40 minutes!

I hope you can attend and join in on the discussion. We are living in strange times: while most of us would probably agree that our GIS analyses are suffering from significant gaps in data, we would probably also agree that at the same time we are struggling under an avalanche of data� That is, what little we do know already seems to be too much to handle. I hope that some of the techniques we discuss can at least partially address these two issues. I welcome your input, thoughts, and experiences.

Topic: British Columbia's iTrim � The Evolution of Topographic Mapping

Speaker: Paul Quackenbush

Company: Base Mapping and Geomatic Services
Land Information Services Division
Government of British Columbia

iTRIM is a data management environment and associated strategies for managing the TRIM base-map dataset and a number of associated derived products. Derived products include the Corporate Watershed Base (CWB), Digital Road Atlas (DRA), Enhanced Base-Map (EBM) and a number of gridded Digital Elevation Model (DEM) products.

September 09, 2004

Topic: Developing British Columbia's Corporate Watershed Base

Speaker: Mark Sondheim, PhD

Company: Base Mapping and Geomatic Services
Land Information Services Division
Government of British Columbia

Using the TRIM I topographic mapping as the source, British Columbia contains on the order of 17 million hydrographic features, including lakes, streams, coastlines, islands, glaciers, and wetlands. Our objective is to add intelligence to this data such that the resulting database can support query operations pertaining to drinking water, fisheries and forestry, planning and assessment, and emergency dispatch and disaster management.

When Phase 1 is complete in early 2005 we will be able to answer such questions as the following: What is the name of a given river? What is its geographic extent? What is the area draining into a given stream? What is downstream/upstream from a given point on the river? What is the gradient of a given location on a river? Which streams are headed by glaciers? Where is a particular bay or channel? If we link the hydrographic data to external databases, then of course we will be able to support a much broader range of queries.

At the core of the CWB development is a series of computational geometry algorithms. With some routines all work is carried out through these algorithms; in other cases some human assistance is required. The routines are used to create skeletons in water bodies, to name rivers, to create routes and hierarchical networks, to determine order and magnitude, to conflate the new dataset to previous versions of the stream network, to determine slope and refined elevation values, to calculate watershed boundaries, and to carry out various kinds of quality assurance.

TRIM I as the CWB source has the advantage of being complete and consistent across the Province. However, the most recent TRIM data contains a much greater degree of detail for over half of BC and is continuing to receive updates. Phase 2 of the project, to commence next fiscal year will center on automated update procedures, some of which may involve Web services. This work will be tied closely to further developments with TRIM data management.

Topic: Using Quickbird Sub-Metre Satellite Imagery for Forestry Applications in BC

Speakers: Karl Kliparchuk and Andrew McIntosh

Company: McElhanney

New commercial satellite platforms such as DigitalGlobe's QUICKBIRD satellite provides imagery of far higher resolution than has been available in the past. Aerial photography, either black & white or color, and of variable scale, is a remote sensing technology that most forest resource managers are currently familiar with. More recently, satellite imagery has begun to offer remote sensing options that can be added to the toolbox of the forest resource manager. The primary objective of this project was to determine the suitability of using the latest in very high resolution satellite remote sensing imagery for resource mapping, effectiveness evaluation, implementation monitoring and as a Compliance and Enforcement tool in variable terrain. Small features can be visually assessed in the imagery and instead of conducting random inspections along the coastal inlets, Compliance and Enforcement staff can monitor and plan more targeted inspections to ensure compliance with government policy.

The imagery was analysed for the purpose of assessing resource features associated with forestry operations in two areas on the west coast. These features include conventional harvesting, roads, landslides, coarse woody debris, riparian areas and deactivation activities

Karl Kliparchuk's Bio

Karl has more than 13 years experience in project management, GIS data compilation, satellite image processing, map projections, cadastral compilation and GIS training. He owned and managed a geomatics company, Terratech Mapping Services Ltd, in Burnaby for 5 years before joining McElhanney as Project Manager for GIS and Remote Sensing. Karl has also been teaching GIS courses part-time for over 8 years at BCIT.

Topic: A New Tool for Improving Coastal Resource Mapping

Speaker: Marc Porter (Inventory Biologist with Fisheries and Oceans Canada)

Marc Porter presented a brief talk describing initial use of ArcPad 6 software by DFO in developing protocols for detailed mapping of marine fisheries habitat. Early efforts to map eelgrass beds in intertidal and subtidal areas of Boundary Bay suggest that ArcPad software and lower-end GPS receivers and data loggers (e.g, IPACs) could represent a fairly low cost, user friendly and effective method for getting community organizations to collect reliable information on coastal resources. ArcPad 6 seems to offer a new platform for seamless integration of field collected data into agency GIS applications and spatial data holdings. The ability of ArcPad 6 software to function with a variety of GPS receivers could also offer major advantages over existing proprietary GPS software/hardware systems currently used by DFO for detailed GPS inventory of freshwater habitats under the auspices of the Sensitive Habitat Inventory and Mapping Program (SHIM).

Gordon Staples of RADARSAT International

Topic: Turning the Scientifically Possible into the Operational Practical: RADARSAT-2 SAR Polarimetric Applications

RADARSAT-2, planned for a mid 2004 launch, is an advanced SAR satellite. Key features of RADARSAT-2 are high resolution (3 m), polarimetric modes, enhanced ground system providing rapid satellite tasking and near-real time data processing, improved image location accuracy, and on-board solid state recorders. The focus of this presentation is on the RADARSAT-2 polarimetric capability. RADARSAT-2 offers three polarimetric modes: (1) selective polarization (dual pol) providing one co-pol channel (HH or VV) and the corresponding cross-pol channel (HV); (2) high resolution (3 m) single pol channel (HH or VV); and (3) a fully polarimetric mode (quad pol) providing both amplitude and phase. The fully polarimetric mode is significant since RADARSAT-2 is the first commercial satellite to offer this mode.

In conjunction with the Canada Centre for Remote Sensing and MacDonald Dettwiler, RADARSAT International initiated application development projects to understand the potential and limitation of the RADARSAT-2 polarimetric modes. An overview of this development work is presented, including agriculture applications, ship detection, forestry, ocean features, DEM generation, and ice mapping. Results based on CV-580 airborne SAR data and SIR-C are used.

Presenter:

Gordon C. Staples received the B.Sc. degree in honours physics and oceanography and the M.Sc. degree in physical oceanography from the University of British Columbia. He joined RADARSAT International in 1993 and was responsible for RADARSAT SAR applications development.

Speaker: Graham Lang, BC Hydro

Topic: Precipitation Magnitude-Frequency Mapping for Southwest British Columbia

Analysis of site-specific precipitation magnitude-frequency is challenging in British Columbia due to short record lengths at most precipitation monitoring stations and sparse data collection networks in many areas. Estimation of watershed-average precipitation for various return periods is even more difficult, particularly for mountainous watersheds. Nevertheless, there are many applications where such estimates are required. For BC Hydro, applications include estimation of common and extreme floods by both deterministic and stochastic methods for analyses of spillway adequacy and dam safety. As well, current methods for estimation of regional Probable Maximum Precipitation require spatial mapping of 100-year, 24-hour precipitation. Consequently, a project was initiated at BC Hydro to produce spatial mapping of 100-year and 1000-year precipitation for 6-hour, 24-hour, and 72-hour durations for Southwest British Columbia.

The use of Geographic Information Systems (GIS) was integral to the project. The study domain includes Vancouver Island, the Coastal Mainland, and northern Washington between latitude 47 and 52 degrees N, bounded on the east by a line approximately along the eastern foothills of the Coast Ranges. GIS was used to produce several intermediate maps required for development of the final product, including maps of L-moment statistical parameters from regional analyses of precipitation magnitude-frequency, as well as maps of mean annual maxima for each duration. The precipitation-frequency information was based on a regional analysis of precipitation annual maxima from over 400 precipitation gauges representing over 18,000 station-years of record.

The maps were produced using a gridded latitude-longitude system with a nominal resolution of 1.25 minutes per grid cell (about 3.6 km2), which for the study domain is a matrix of 241 rows by 481 columns. Final GIS maps were produced in gridded and isopluvial (contoured) form.

Topic: GIS Technologies in Medical Geography

Epidemiological geography investigates the correlation between different types of environments and human diseases. Within the framework of this, Pasteur Institute of Saint Petersburg, Russia has been collecting for decades information about a number of infectious diseases.

In the 1990s St. Petersburg faced a sudden epidemic and epizootic of leptospirosis � an acute fever disease, common in animals and people. The question of the source of the disease for people became very important for different scientific schools and municipal officials.

In 1998, the Pasteur Institute started to use GIS technologies to analyze possible causes and patterns of spreading of the disease. The Institute has registered about 5000 cases of infected dogs, thousands of rats, and more than 900 cases of people�s disease in the last 10 years. This data was converted to a digital form and geocoded (address point were created).

The most difficult type of spatial analysis is �point-to-point� analysis. The presentation covers some techniques used in this work, including overlay operations, grid and pseudoisolines analysis. Results were brought into the �Atlas of Leptospirosis�, where thematic maps show different aspects of the common picture of the disease in Saint Petersburg.

Topic: Characteristics and Features of Ikonos High Resolution satellite imagery.

Web based systems can provide users with read-only access to GIS data across an Intranet or the Internet. These systems are deployed using a three-tier architecture that consists of a database, a business process server, and a number of client applications.

A client application is usually implemented as either a web page or a stand-alone executable written in a language such as Visual Basic or Java. The design of the client application must consider not only the features that are to be made available to the end users, but also the most appropriate mechanism for deploying the application across an organization. Determining whether a web-page solution or a stand-alone solution will best meet requirements is of primary importance, but determining which is the best option to meet the needs of your organization can be difficult.

This presentation addresses the design, implementation, and deployment of these two types of client applications. It provides an overview of the issues associated with each and, based on past project experience, how to determine which will be the best option for delivering GIS functionality to end-users.

Mr. Nimmo has spent much of his career designing and implementing GIS/AM/FM systems in a number of industries including eight years in mineral exploration with Placer Dome, five years with the Department of Fisheries and Oceans and two years with a consulting firm servicing utility and telecommunication companies.

Topic: Applying Knowledge Based Techniques To Making Spatial Decisions

The phrase knowledge based techniques can refer to a wide spectrum of methods; in this case it is specifically referring to the capture of expert knowledge into a hierarchical decision tree. This forms the basis of an algorithm used to process data resulting in decisions being made on the data. These algorithms have been referred to as knowledge base algorithms, expert systems, decision trees, inference trees and multi-criteria processing. This technique is not restricted to any particular application or line of business as illustrated by the two examples discussed, but there are a few critical rules/guidelines that are required to be followed to ensure a successful design. The two examples to be discussed will include an approach using for mineral exploration and a second similar approach used for fisheries habitat management purposes. In both cases there was a large volume of data to be interpreted, made up of many layers each varying in sample density. To manually analyze such a large volume of data the interpreted results are often in inconsistent due to personal biases of each analyst and changing priorities over the time of the project. Also if new knowledge and/or data were made available the additional analysis required would add further to an already long project. By applying this technique both projects produced a consistent interpretation throughout the project area and identified opportunities that would not have been considered through manual methods.

Speaker: Dale Lutz, Safe Software

Topic: Slaying the Spatial Data Exchange Dragon ** For Fun and Profit **

Abstract: Spatial data interoperability continues to be a major issue facing organizations with a spatial aspect to their enterprise. Whether it's professionals in the business of making or updating maps, or decision makers using spatial data as part of their process, having easy access to existing spatial data is critical to the profitability and quality of the outcome. Traditionally, incompatibilities between spatial data formats (both CAD and GIS) have severely hampered spatial data exchange, sometimes even within organizations. After many years, solutions to this seemingly unsolvable problem are now appearing. The talk will survey some of the recent developments that are starting to make a difference. Interoperability improvements to mapping software, initiatives in spatial database standardization (SQL3/MM), Open GIS Consortium standards, Open Geospatial Datastore Interface (OGDI), web based mapping servers, and improved translation software will be discussed. Concrete examples of how each are being employed NOW by organizations to streamline their processes will be given. Finally, recommendations for reducing time and money spent on data exchange projects will be shared.
