The Federal Emergency Management Agency (FEMA) has produced two flood map products. The first product is called Q3 Flood Data and corresponds to FEMA's 1999 FIRM flood maps, and is available for over 1300 counties in the U.S. in spearate files by state. FEMA then created Digital Flood Insurance Rate Maps (DFIRMs). As part of Flood Map Modernization, FEMA will only update or produce DFIRMs.
DFIRMs can be accessed via Maptitude by downloading the an XML file and then using the Map > Imagery > FEMA Flood Hazard Zones command.
Historical FEMA flood zone designations are available in Caliper CDF format for use with Maptitude and TransCAD.
