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.
