GloFIMR is an extension of the USFIMR project that commenced in August 2016 with funding from NOAA. The project’s main goal is to provide high-resolution inundation extent maps of 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, Sentinel-2). The maps are accessible via the online map repository below. The repository is under development and new maps are added upon request.

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

Flood inundation maps are listed on the map side panel  Screen Shot 2016-09-01 at 9.58.36 PM  and at the table below.  

Flood layer properties and download links* will be listed once a layer is selected from the side panel or the map.

* Download links will not work when using ‘Safari’ web browser

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

Download the entire dataset in Shapefile format.

NOTE: Rendering of the flood inundation layers at the Google Maps display is at a considerably lower spatial resolution than the actual (shapefile) layers.
