Landsat TM ETM+ Bulk Reprocessing

The Landsat Thematic Mapper (TM) is a multispectral scanning radiometer that was carried on board Landsat 4 and 5 missions. The TM sensors have provided nearly continuous coverage from July 1982 to present. The Landsat Enhanced Thematic Mapper Plus (ETM+) was introduced with Landsat 7. ETM+ data cover the visible, near-infrared, shortwave, and thermal infrared spectral bands of the electromagnetic spectrum.
The Landsat Project is a joint initiative of the U.S. Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA). Landsat's Global Survey Mission is to establish and execute a data acquisition strategy that ensures repetitive acquisition of observations over the Earth's land mass, coastal boundaries, and coral reefs.
Even though the Landsat Program is managed by USGS, and data from Landsat was collected and distributed from the USGS's Center for Earth Resources Observation and Science, many ESA ground stations acquired and processed Landsat data.
The reprocessing of the entire TM and ETM+ dataset has been started in January 2020 using the last ESA IPF versions 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 TM/ETM+ dataset holding, including its repatriation to ESA.
