Global Land Survey 1975Entry ID: GLS_1975
Abstract: Global Land Survey 1975 images were acquired from 1972 to 1987 by Landsat 1-5 MSS. Landsat 4-5 data were used to fill gaps in the Landsat 1-3 data.
The U.S. Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA) collaborated on the creation of the global land datasets using Landsat data from 1972 through 2008. Each of these global datasets was created from the primary Landsat sensor in use at the time: the Multispectral Scanner (MSS) in the 1970s, the Thematic Mapper (TM) in 1990, the Enhanced Thematic Mapper Plus (ETM+) in 2000, and a combination of TM and ETM+, as well as EO-1 ALI data, in 2005.
