Land Cover

The USGS collects and maintains data that show both natural and manmade land cover of the United States. These data are collected from orbiting satellites and have been produced for 2 years, 1992 and 2001. The 1992 data set encompasses the conterminous United States, whereas the 2001 data set encompasses all 50 states and Puerto Rico. In addition, a land-cover change product between 1992 and 2001 also is available. These data sets use a 21-class land-cover classification scheme that includes urban, agricultural, rangeland, forest, surface waters, wetlands, barren lands, tundra, and perennial ice and snow classes. The spatial resolution of the data is 30 meters. Further information and data download available at: http://www.mrlc.gov/.
