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.
Category-1 access to data is available. More information can be obtained at EOPI.
The data are in CEOS format, and are of type LANDSAT.TM.SCPRNN for Landsat 7 and LANDSAT.TM.SCPRCC for Landsat 5. The data may be seen and downloaded from EOLI web.
Landsat ETM+ acquisition is suspended since May 2003.
Data
The distribution of the data acquired by Landsat TM/ETM follows a specific agreement with Eurimage and is governed by the ESA Data Policy.
