What is NLCD data?
The National Land Cover Database (NLCD) provides nationwide data on land cover and land cover change at a 30m resolution with a 16-class legend based on a modified Anderson Level II classification system. The database is designed to provide cyclical updates of United States land cover and associated changes.
Where can I get land cover data?
Data are available on the MRLC website, either as prepackaged products or custom product areas can be interactively chosen using the MRLC viewer.

How is the NLCD created?
NLCD is coordinated through the 10-member Multi Resolution Land Characteristics Consortium (MRLC), a two decades-long interagency federal government collaboration that has proved an exemplary model of cooperation among federal agencies to combine resources to provide digital land cover information for the Nation.
What imagery is the NLCD primarily derived from?
Land use and land cover data are available from two sources, the United States National Agricultural Statistics Service (NASS), and the United States Geological Survey National Land Cover Database (NLCD) from The National Map. Information from these sources is primarily derived from classification of satellite imagery.
What are land cover types?
