USGS EROS Archive - Landsat Legacy - Global Land Survey (GLS)
Science Center Objects
The U.S. Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA) have collaborated on the creation of the Global Land Surveys (GLS) datasets. This collection contains images acquired from 1972 to 2012.
The U.S. Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA) collaborated from 2009 to 2011 to create the Global Land Surveys (GLS) datasets. Each of these collections were created using the primary Landsat sensor in use at the time for each collection epoch. The scenes used were a pre-collection format that met strict quality and cloud cover standards at the time the GLS files were created.
Additional details about the Global Land Survey collection.
The Global Land Survey collection consists of images acquired from 1972 to 2012 combined into one dataset.
All Global Land Survey datasets contain the standard Landsat bands designated for each sensor. Band Designations information.
