Global Land Survey Examples

Global Land Survey Examples

Examples of the GLS 2005 images for Saskatchewan. These images illustrate the four data layers in this global data set of Landsat imagery: the 1970s, 1990, 2000, and 2005. All four data layers were geometrically corrected to the terrain using the 2000 Landsat-7 data layer as the rectification basis. These data are now being distributed free of charge through NASA and the USGS. Credit: G. Gutman, NASA/Headquarters; J. Masek, NASA/Goddard Space Flight Center; C. Justice and S.
