Resource Abstract:
- description: The National Flood Hazard Layer (NFHL) is a compilation of GIS data that comprises a nationwide digital Flood
Insurance Rate Map. The GIS data and services are designed to provide the user with the ability to determine the flood zone,
base flood elevation, and floodway status for a particular location. It also has information about the NFIP communities, map
panels, cross sections, hydraulic structures, Coastal Barrier Resource System, and base maps such as road, stream, and public
land survey data. Through flood studies, FEMA produces Flood Insurance Study Reports, FIRM Panels, and FIRM Databases. FIRM
Databases that become effective are incorporated into the NFHL. Updates to the NFHL are issued through Letters of Map Revision
(LOMRs) and Letters of Map Amendment (LOMAs). Continuously updated, the NFHL serves as a Digital Flood Insurance Rate Map
representing the current effective flood data for those communities where maps have been digitized. NFHL data can be viewed
with widely available GIS software, including freely available programs that work with GIS shapefiles. For more information
on the NFHL, see the online resources referenced herein. ___Using base maps:___ The minimum horizontal positional accuracy
for base map hydrographic and transportation features used with the NFHL is the NSSDA radial accuracy of 38 feet. ___Letter
of Map Amendment (LOMA) point locations___ are approximate. The location of the LOMA is referenced in the legal description
of the letter itself. LOMA points can be viewed in the NFHL Interactive Map on the FEMA GeoPlatform.; abstract: The National
