The US Geological Survey seeks information to determine if there is interest by one or more commercial or non-profit vendors in offering Landsat products beyond those available from the US Geological Survey (USGS). The USGS has available Landsat TM and ETM+ data in a raw, uncorrected format (Level-0R) so that these data could be processed to user specifications (projection, datum, and resampling method). Responses are due by September 12, 2008. Details can be found at FedBizOpps.
More frequent satellite observations, such as those of the Harmonized Landsat Sentinel-2 (HLS) dataset, are needed to fully capture flood dynamics in regions experiencing short-lived, ephemeral flooding.
