USGS Announces Free Access To Satellite Image Archive
If you need information on land use changes over time, or on current land uses and character, you may want to check out decades-worth of globe-spanning satellite images that USGS made freely available to the public on Dec. 30, 2008. The Landsat images (via instruments on board Landsat 1-5) were taken from 1972 to the present. On Oct. 1, 2008, USGS took a similar step with Landsat 7 images taken from 1999 to the present. The various instruments capture different kinds of information about the earth.
