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 currently under development and new maps are 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 (dsnanayakkaramunasinghe@crimson.ua.edu) and James Misfeldt (jamisfeldt@crimson.ua.edu). (formerly Bradford Bates). 

Flood inundation maps are listed on the map side panel   and at the table below.  

To view an inundation extent polygon layer: zoom-in to a layer location (indicated by the  point symbol) and make it visible from the ‘Legend’ side panel   bar on the left. Click on the point symbol to identify the layer’s name.

Flood layer properties are available by clicking on flood polygons.  Download links* can be found by clicking on the associated point symbols.

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