Accurate information about risks is the first step in preventing and reducing losses.
Flood Map Modernization
IntroductionIntroduction
To support the vision, “A Nation Prepared,” the Federal Emergency Management Agency (FEMA), has undertaken the Map Modernization effort to update the Nation’s flood hazard maps.

The geospatial platform will be the repository for the national GIS data layer and will store the following:
• Final Digital Flood Insurance Rate Map (DFIRM) data
• Intermediate data, including the outputs of key steps used to create the DFIRM data. Scoping Survey Elevation Hydrology and hydraulics modeling data Base Flood Elevations (BFEs) Flood outlines and other pertinent data

Purpose of Data Capture StandardsPurpose of Data Capture Standards
Provide a consistent framework for collection, storage, and retrieval of the data needed for a Flood Insurance Study (FIS)
Describe what needs to be captured from digital data that was used in the FIS
Capture key data required for model maintenance and quality control
Verify that the data can be accessed easily and used for other projects
