GIS Tools for Emission Inventories

Air Protection Cross Branch Seminar

May 13,2004

Air Protection Section

two systems
Two Systems
  • Air Contaminant Emissions (ACE) for Area and Mobile Sources
  • Air and Emissions Information of British Columbia (AEI) – Web Based System
ace background
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
slide4
ACE
  • System
  • GOAT Maps
  • Gridding
  • Airshed Selection - Quesnel
  • Reporting - Oracle Discoverer
  • Data Drill Down
  • Data Dictionary
ace gridding
ACE - Gridding
  • 1 km or 5 km grid squares
  • BC Albers projection – simplicity and coherence with BC gov standards
ace data dictionary
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
slide15
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
end uses
End Uses?
  • Airshed Management Planning
  • Dispersion Modelling
  • State of Environment Reporting
  • Information Requests
future directions
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)
