Data DescriptionRiver and Surface Flood Map Products (RSVFM) - The River and Flood Forecast Maps data family includes flood map products generated from imagery acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS). In the future additional flood map products generated from the Geostationary Operational Environmental Satellite (GOES) instrument will be included in this data family. The VIIRS instrument includes 22 spectral bands: 16 moderate-resolution, narrow-spectral-band at 750 meter resolution, five imaging-resolution, narrow-spectral-band at 375 meter resolution and one Day-Night Band imaging broadband at 750 meter resolution. The VIIRS 1-Day and 5-Day flood map products are generated from the VIIRS NRT Global Flood EDR at a resolution of 375 meters. These composite products are rendered using Area of Interest (AOI) maps. The globe is divided into 136 (15 x 15 degree) AOI maps, with each map showing the maximum 1-Day or 5-Day AOI flood extent. The 1-Day product is generated by compositing VIIRS NRT Global Flood EDR granules into AOI maps and the 5-Day product is generated by aggregating the 1-Day maps over a five day period. This data set is produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS) and is distributed by the Comprehensive Large Array-Data Stewardship System (CLASS) as 15 degree AOI interest files in the NetCDF file format with metadata attributes included.
