Digital Vision: A New Generation of Maps

FEMA Flood Map Modernization (Map Mod) efforts have generated new digital flood hazard products as part of the multi-year effort to update the flood maps in the United States and deliver these maps digitally. The new maps are reliable, easier to use, and readily available.

Our Vision for the Future

FEMA has distributed many map products in a digital format during the past few years, resulting in a 50‑percent reduction in paper map orders from the Map Service Center (MSC). Online product delivery provides users with the information they need quickly, often at no cost, bypassing the need for mail delivery of paper products. Users can still order a paper map from the MSC website or by telephone at 1-800-358-9616.

Digital Products Available Now

A FIRMScan is a full-size digital image of any paper map that can be ordered or downloaded from the MSC. In addition, users can create a digital FIRMette, the simplest way to access flood hazard information for a specific location. FIRMettes show a section of the official Flood Insurance Rate Map (FIRM). FIRMettes can be printed on a standard office printer and include the map scale, north arrow, and the map identification information that is used in all aspects of the NFIP, including floodplain management, flood insurance, and enforcement of mandatory flood insurance purchase requirements. Users can create a FIRMette free of charge on the MSC website.

Geographic Information System (GIS) users can employ the Digital Flood Insurance Rate Map (DFIRM) database product that has been designed for use with specialized GIS software. Using the DFIRM database in a GIS provides a more flexible and powerful tool for mapping and analysis than traditional map products can provide. DFIRM databases can be downloaded or delivered on a compact disc (CD) from the MSC. GIS users can also access GIS flood data as a Web mapping service. Access the “Tools and Links” page on the website for information about the Web mapping service.

For users who want to do more than the basic FIRMette product allows, the DFIRM Map Viewer provides some of the capabilities of GIS online. Users have more control over the display of flood hazard information and other mapping information shown on the Map Viewer, including the ability to combine flood hazard information with maps of other hazards. The Map Viewer is also available on the MSC website.

Getting the Right Information Out Quickly

FEMA updates the GIS version of the flood maps each time a Letter of Map Revision is issued. By the end of 2007, this updated version of the data was being displayed on the Map Viewer, and planning was under way for distribution of these data. FEMA is committed to making mapping products as user friendly and accessible as possible.
