See the Global Flood Inundation Map Repository (GloFIMR) portal (based on Google Maps) here. GloFIMR includes the USFIMR maps.

The USFIMR project commenced in August 2016 with funding from NOAA. The project’s main goal is to provide high-resolution inundation extent maps of past U.S. flood events to be used by scientists and practitioners for model calibration and flood susceptibility evaluation. The maps are based on analysis of Remote Sensing imagery from a number of Satellite sensors (e.g. Landsat, Sentinel-1) with some ground proofing based on secondary sources (e.g. news reports, social media). The maps are accessible via the online map repository below. The repository is actively updated with new maps added on a weekly basis.

For information, requests and data contribution contact the project PI: Dr. Sagy Cohen (sagy.cohen@ua.edu) or Lead Developers: Dinuke Munasinghe and Austin Raney
(formerly Bradford Bates and James Misfeldt ).

Flood inundation maps are found via the search box and listed in the table below.

Flood layer properties and download links* will be listed once a layer is selected by clicking on its polygon within the map.

*Download links will not work when using Safari web browser

The dataset can also be accessed directly via Google Maps, ArcGIS Online or through the SDML Datasets Portal.
