Global Land Survey 2010
With over 3 million images in the USGS Landsat archive, choosing the best scenes can be daunting. The USGS and NASA have collaborated on global land datasets that represent examples of the best Landsat scenes from circa 1990, 2000, and 2005. NASA and the USGS have again partnered to develop the Global Land Survey 2010 (GLS2010), a new global land dataset with core acquisition dates of 2009–2011. The dataset includes Landsat 5 Thematic Mapper (TM), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), and Earth Observing Mission 1 (EO-1) images. GLS2010, and all other decadal datasets, can be downloaded at no cost at GloVis or EarthExplorer.
