Background Information
Sample map Sample Map
Land cover data describe the nature of the land surface at a particular location. The staff at the U.S. Geological Survey (USGS), National Center for Earth Resources Observation and Science (EROS) compile land cover data as part of the USGS Land Cover Characterization Program (LCCP). The LCCP was started in 1995 to address National and International requirements for land cover data that were becoming increasingly sophisticated and diverse. The program develops multi-scale land cover characteristics databases; studies the patterns, characteristics, and dynamics of land cover across the Nation and the Earth; pursues research that improves the utility and efficiency of large-area land cover characterization and land cover characteristics databases; and serves as a central facility for access to, or information about, land cover data.

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 Map Small-Scale Collection also includes a 1 kilometer resolution image showing general North American Land Cover Characteristics , with classification based on the Anderson classification scheme.
