Landsat TM Processing
Landsat Thematic Mapper (TM) is a multispectral scanning radiometer that was carried on board Landsats 4 and 5 satellite which are the fourth and fifth satellite of the Landsat program, result of the joint effort of National Aeronautics and Space Administration (NASA), National Oceanic and Atmospheric Administration (NOAA), Earth Observation Satellite Company (EOSAT), Department of the Interior (DOI) of the USGS, General Electric (GE), Astrospace, and Hughes Santa Barbara Remote Sensing.
Landsat 4 was launched on July 16, 1982, and was operative until December 1993. Landsat 5 was launched on March 1, 1984, and was operative until December 2012. They embarks 2 payloads: the Thematic Mapper (TM) and Multi-Spectral Scanner (MSS); the first one was operated from Jul 1982 to November 2011 and very few images were acquired from November 2011 to May 2012
Even though the Landsat Program is managed by USGS, and data from Landsat 4 and 5 was collected and distributed from the USGS's Center for Earth Resources Observation and Science, many ESA ground stations acquired and processed Landsat TM data. The reprocessing of the entire dataset has been started in January 2013 and is currently on-going, performed by the eXpert Product Reprocessing Scalable Service X-PReSS consortium under the ESA management.
The X-PReSS consortium - formed by Serco SpA, Ifremer, Magellium, S&T, CATAPULT, ENGINEERING and SISTEMA, - aims at collecting, consolidating, processing and delivering the entire ESA Landsat-4 and 5 TM dataset holding, including its repatriation to ESA.
