  1. GIS Tools for Emission Inventories Air Protection Cross Branch Seminar May 13,2004 Tony Wakelin, Air Protection Section

  2. Two Systems • Air Contaminant Emissions (ACE) for Area and Mobile Sources • Air and Emissions Information of British Columbia (AEI) – Web Based System

  3. ACE - Background • GOAT – GIS Oracle Access Tool • Spatial and attribute exploration and reporting - Airshed specific • Uses 1995 data – plan to upload with year 2000 • BC excluding the LFV

  4. ACE • System • GOAT Maps • Gridding • Airshed Selection - Quesnel • Reporting - Oracle Discoverer • Data Drill Down • Data Dictionary

  5. ACE - System

  6. ACE - GOAT Maps

  7. ACE - Gridding • 1 km or 5 km grid squares • BC Albers projection – simplicity and coherence with BC gov standards

  8. ACE - Gridding (cont’d)

  9. ACE - Airshed Selection - Quesnel

  10. ACE - Inventory Reporting

  11. ACE - Reporting – Oracle Discoverer

  12. ACE - Data Drill Down

  13. ACE - Data drill down (cont’d)

  14. ACE - Data Dictionary • Describes how various spatial data sets were used for 1 km and 5 km gridding • Example – Residential heating • 9 ecoprovinces defined by EC (Quesnel – Central Interior) • Average temperature data Oct to Mar • Relative thermal factors

  15. AEI • Web based system (Arc IMF) • Point, Wildfire, and Prescribed Burning • Ambient Monitoring Sites • Have demonstration site • Working on Government data model – allows Oracle update to be carried into GIS

  16. AEI

  17. AEI

  18. AEI

  19. End Uses? • Airshed Management Planning • Dispersion Modelling • State of Environment Reporting • Information Requests

  20. Future Directions • Web based system has merits and ACE could be migrated over • Common multi-agency platform is in the process of being developed by EC, GVRD and WLAP • Going to need better spatial data (vehicle emissions)
