LANDSAT

LANDSAT

Series began in the second half of the 1960s, from a project developed by the National Aeronautics and Space Administration (NASA). It was exclusively dedicated to the observation of terrestrial natural resources. This program was initially called ERTS (Earth Resources Technology Satellite) and in 1975 was renamed Landsat. Landsat-1 was the first satellite developed to work directly on research of natural resources. It was launched in 1972 and named ERTS-1 or Landsat-1. It was the first remote sensing satellite in the world and took two instruments on board, RBV and MSS cameras. It operated for a period of five years acquiring more than 300,000 images, with repeated coverage of the Earth's surface.

Eight satellites were launched, all with multispectral images. In our catalog you will find images from Multispectral Scanner Sensor (MSS), 80 m spatial resolution, for Landsat satellites 1, 2 and 3 (1972-1992); Thematic Mapper sensor (TM) 30 m spatial resolution, for Landsat-5 (1984-2011), Enhanced Thematic Mapper Plus sensor (ETM +) from 15 to 30 m resolution in Lansat-7 satellite ( since 1999) .and OLI sensor (Operational Land Imager) and TIRS (Thermal Infrared sensor) 15 to 30 meter multispectral data from Landsat 8 (since 2013). Landsat-8 images are orthorectified and all catalog products are in GeoTIFF format.
