Geospatial Web Portal for Regional Evacuation Planning

摘要

Evacuation of a regional population is often necessary when a disaster, such as wildfire or coastal flooding, is in the forecast. We build a map-based web portal for the planning of an evacuation of a region. A user marks a polygon on the map to indicate the extent of the region that will be evacuated. The population affected and the home value that will be impacted is calculated. The system then assigns local communities to different shelters. The evacuation plan for each local community in the region is then displayed. Underpinning the web portal is a data structure organized geographically by the U.S. postal service zip code that contains the population and a home value index. The implementation uses the Mapbox GL JS library.
