The GLCF is a center for land cover science with a focus on research using remotely sensed satellite data and products to assess land cover change for local to global systems. Provides access to Landsat, Aster, MODIS, AVHRR and SRTM products.

A list of sources of land cover data

The Multi-Resolution Land Characterization (MRLC) consortium is a group of federal agencies who coordinate and generate consistent and relevant land cover information at the national scale for a wide variety of environmental, land management, and modeling applications.
There are datasets from 1992, 2001, 2006, and 2011. Many of these can also be downloaded from the National Map: viewer.nationalmap.gov

The GAP national land cover data, based on the NatureServe Ecological Systems Classification, are the foundation of the most detailed, consistent map of vegetative associations ever available for the United States

A comprehensive, statewide database of spatial information for mapping and analysis supporting emergency response, environmental planning and management, transportation planning, economic development, and transparency in state government operations

The USDA NASS Cropland Data Layer (CDL) is a raster, geo-referenced, crop-specific land cover data layer for the United States.

The Cropland Data Layer (CDL), hosted on CropScape, provides a raster, geo-referenced, crop-specific land cover map for the continental United States. The CDL also includes a crop mask layer and planting frequency layers, as well as boundary, water and road layers. The data is created annually using moderate resolution satellite imagery and extensive agricultural ground truth.

Using the EROS FOREcasting SCEnarios of Land-Cover (FORE-SCE) model, EROS scientists are modeling land-cover change both into the future, using scenario-based modeling approaches, and for "backcasting" land cover for historical periods. In combination with USGS remote sensing based land-cover data, EROS' modeling efforts result in consistent, annual land-cover maps from 1938 through 2100, with multiple scenarios of potential land cover for future periods.

Historical land-use and land-cover data, available from the U.S. Geological Survey (USGS) for the conterminous United States and Hawaii, have been enhanced for use in geographic information systems (GIS) applications. The original digital data sets were created by the USGS in the late 1970s and early 1980s and were later converted by USGS and the U.S. Environmental Protection Agency (USEPA) to a geographic information system (GIS) format in the early 1990s.

Derived from the early to mid-1990s Landsat Thematic Mapper satellite data, the National Land Cover Data (NLCD) is a 21-class land cover classification scheme applied consistently over the United States. The spatial resolution of the data is 30 meters and mapped in the Albers Conic Equal Area projection, NAD 83. The NLCD are provided on a state-by-state basis.

The Historical Land Cover and Land Use data set consists of two files, and was developed to provide the global change community with historical land use estimates. The data set describes historical land use changes over a 300-year historical period (1700-1990).

Part of the US Department of Agriculture. It provides maps, charts, and historical data about crops, livestock, economics, and research. Historical data goes back to 1970. It also includes an agricultural chemical use database that allows the user to map a specific crop and the amount of pesticides used to treat it.

Includes links to maps and data sets for a variety of USDA data.

In a multi-partner collaboration centered on the International Livestock Research Institute (ILRI), the Food and Agriculture Organization of the United Nations (FAO) and the Université Libre de Bruxelles (ULB-LUBIES), global maps of livestock distributions and production systems are being revised and updated.
The Geo-Wiki is used to provide a central viewer, validation tool and repository for these data.
