Landsat Thematic Mapper (TM) is a multispectral scanning radiometer that was carried on board Landsats 4 and 5. The TM sensors have provided nearly continuous coverage from July 1982 to present. The Landsat Enhanced Thematic Mapper (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.

For the last 30 years, the European Space Agency (ESA) has been providing Earth Observation (EO) data, technical information and data analysis tools in support of EO satellite missions. The HEDAVI (HEritage DAta Visualisation) service enables users to discover a wealth of heritage data from ESA's ERS and Envisat missions, as well as from Landsat-5 and Landsat-7, two important heritage Third Party missions at ESA, through ESA's heritage data programme ‘LTDP'.
