Web-based GIS Decision Support Tools

The figure above shows the estimated extent and depth of storm surge for a category 3 hurricane in the area around Charleston, South Carolina, modeled from a web-based tool that accesses FEMA’s Coastal Flood Loss Atlas for input data.

This project emphasizes the development and application of a variety of web-based analysis and decision support tools. One such tool is the USGS Flood Inundation Mapper which estimates losses to buildings and other infrastructure from catastrophic flooding. This tool will help local planners and emergency response personnel in cities and towns across the country better prepare for and respond to catastrophic floods. Another tool is the IMMAGE application (Internet-based Modeling, Mapping, and Analysis for the Greater Everglades), which allows local water managers to access the results from USGS computer models that predict the extent of saltwater intrusion from sea level rise and the threat to local water supplies. Another web-based resource, developed in collaboration with the Federal Emergency Management Agency (FEMA), is a portal which contains modeled projections of storm surge from coastal storms along the East and Gulf Coasts and the resulting physical and economic, and social losses.
