ESRI, the leading developer of geographic information system (GIS) software, has announced that Federal Emergency Management Agency (FEMA) flood data has been added to the Geography Network’s extensive collection of georeferenced data. The Geography Network ( www.geographynetwork.com) is a framework for building and launching a commercial data distribution mechanism over the Internet.
Geography Network users can now download FEMA Q3 Flood Data to use with GIS software such as ArcGIS and ArcExplorer—Java Edition. Using GIS software, users can overlay the Q3 Flood Data with their own information (street networks, land parcels, customer addresses, etc.) to display zones of potential flood risk and identify future marketing opportunities. Q3 Flood Data is available for 1,293 U.S. counties, representing 76 percent of U.S. households.
