Land Cover
USGS land use on the GEMS GridDescription
This API enables exploration of land cover data for the conterminous United States. Currently 3 products are offered: Land Change Monitoring, Assessment, and Projection (LCMAP), The National Land Cover Database (NLCD), and Cropland Data Layer (CDL) for Minnesota. These products help characterize land cover and land cover change spatially and temporally in a systematic and consistent way to support a variety of research objectives focused on natural and human-made systems across the United States.
