  1. Heavy Traffic How The BC Integrated Land Management Bureau Used Open Source to Deploy Government-Strength GeoWeb Services Michael Ross GeoWeb Arrghitect Integrated Land Management Bureau Province of British Columbia michael.ra.ross@gov.bc.ca FOSS4G 2007 Victoria, BC September 2007

  2. 1:7 000 000 Base Map

  3. TRIM 1:20 000 Base Map

  4. OGC Catalogue Service v1.0

  5. Integrated Cadastral Fabric WMS

  6. GeoWeb Services Architecture Aug 1, 2007 OGC-compliant Mapping Tool ArcMap, Google Earth, GAIA, JUMP Web Browser IMF application (e.g.,iMapBC, BMOS, CoinPacific, Mapster, NFIS) Client Tier Apache Web Server Web Server Tier OGC Web Service Tier MapServer WMS Airphoto Index Base Cadastre Forest Vegetation Wildlife Management Terrestrial Ecology Water Management ArcIMS with OGC WMS Connector Base and Forest Veg GeoServer WFS LRDW Feature Service* Earth Resources Image Web Server WMS Orthophoto Imagery Satellite Imagery DIS Imagery Warehouse Land and Resource Data Warehouse Data Tier JP2/ECW images OracleDatabase ArcSDE *internal useonly

  7. In The Beginning (2002) There Was An Interoperability Problem Warehouse designed to support internal clients External clients needed online access to TRIM, Forest Cover, and Imagery(CFS, DFO Pacific, public) CGDI To The Rescue Used ArcIMS 4 OGC Connector Single WMS serving TRIM and imagery 2,000 hits per month

  8. Gearing Up • Imagery Server Evaluation Source 1. Software Evaluation for DIM, Final Report v1.1; BC Ministry of Sustainable Resource Management; September, 2003; Performance Test p.2.8

  9. Gearing Up How Many Eyes Looking at MapServer/SDE or GeoServer/SDE? None Initial Evaluation Poor Performance No SDE 9 support Enhanced MapServer/GeoServer Connection pooling SDE 9 support

  10. Gearing Up WMS Re-evaluation • MapServer • ArcIMS Source 1. Land Information BC Open Infrastructure WMS Final Test Results, BC Ministry of Sustainable Resource Management, 2005

  11. Cruisin' MapServer/GeoServer In Production Stable Good Performance Easy to administrate Supports complex styles and SLD's Good support both locally and globally

  16. Bumps Along The Way • Added support for SDE Joins in MapServer • Discovered performance problem in ArcIMS X Source Performance Comparison: ArcSDE Joins in MapServer vs. ArcIMS, BC Ministry of Environment, 2007

  17. Bumps Along The Way Mt Seymour @ 1: 60 000 Scale After Scale Range Adjustment Mt Seymour @ 1: 60 000 Scale Before Scale Range Adjustment

  18. Bumps Along The Way Before After Annotation Orientation Problem

  19. Bumps Along The Way ArcSDE Patch Failure MapServer/ GeoServer ArcSDE Shape PostGIS db2 Oracle Cross-dbms support gave us elbow room

  20. Bumps Along The Way

  21. The Road Ahead 200 WMS layers defined, 1,000 to go WFS access Transactional WFS Support Gazetteer Service GeoWeb Processing Services Plotting Service 3D Stereo Service
