Abstract
 Urban Wildfire Exposure Modeling in the Municipality of Anchorage, Alaska Track: EMS/Fire Author(s): Charles Barnwell, Susanne Rodman, John Koltun The Anchorage Wildfire Exposure Model (AFEM) is an ArcGIS extension for fire exposure modeling developed for the Municipality of Anchorage, Alaska (MOA). The AFEM generates a fire exposure map that reflects the potential threat of wildfire throughout MOA wildland/urban interface area. The AFEM automates the analyses of MOA GIS data for the calculation of the exposure components: potential fire intensity, values at risk, suppression constraints, and ignition risk. The AFEM conceptual design was first implemented and refined using ArcGIS ModelBuilder. This allowed the fire scientists to visualize the process flow of GIS data through the model and evaluate the impacts of the weights and parameters on the calculation of the exposure components. After implementation in ModelBuilder, AFEM was converted using the ArcObjects extension with a custom interface and extended processing options. AFEM is currently being used to guide mitigation efforts and evaluate what-if scenarios for urban development options.
