Digital Flood Insurance Rate Map (DFIRM)

Definition

A flood insurance map developed by the Federal Emergency Management Agency (FEMA) for use with Geographic Information Systems (GIS) technology. This product is considered an "intelligent" map, more than just digital drawings. The map is a computer-based analytical tool that can be used for automated analysis and map updates that are not possible with the current paper maps. DFIRM data are now available for many of the highest flood risk areas.
