GIS-Based Emission Inventory Tool (EIGIS)
RWDI has worked with Environment Canada and other stakeholders to develop EIGIS,
a unique software system that is the foundation of a new conceptual paradigm for
computing emissions inventories. EIGIS follows a bottom-up approach by computing
emissions using spatially resolved activity data, obtained and stored as high-resolution
GIS layers. Sample GIS-based activity layers include: road networks and traffic
volumes, population statistics, and land use. EIGIS has been used for pilot projects
in Canada and the U.S. to compute and analyze emissions estimates, generate reports,
and prepare SMOKE model input files.
