Sample Map
Land cover data are used for a wide variety of global, national, and regional applications, including global change research, environmental inventories, watershed management, and land use planning. The USGS, in cooperation with the U.S. Environmental Protection Agency, National Oceanic and Atmospheric Administration, and the U.S. Forest Service, has produced a land cover data set for the conterminous United States, derived from 1992 Landsat thematic mapper imagery and supplemental data. This National Land Cover Data 1992 (NLCD) is a component of the LCCP. The seamless NLCD contains 21 categories of land cover information based on a modified Anderson land cover classification, and has been subjected to a rigorous accuracy assessment. Further information on collection and accuracy assessment procedures can be found on the National Land Cover Data: Mapping Procedures page. The Conterminous United States Land Cover 1992 – 200 Meter Resolution map layer is an image showing 21 classes of land cover, with an additional class identifying non-U.S. land. Included are water, barren land, shrubland, grasslands, developed land, forests, orchards, cropland, and wetlands. Staff at EROS derived the map layer from the NLCD. Detailed information on the classification scheme can be found on the NLCD Land Cover Class Definitions page. The National Atlas also includes a 1 kilometer resolution image showing general North American Land Cover Characteristics, with classification based on the Anderson classification scheme. |
