The Geological Survey is compiling land use and land cover and associated maps for the entire United States. Land use refers to man's activities which are directly related to the land. Land cover describes the vegetation, water, natural surface, and artificial constructions at the land surface. These maps will help satisfy a longstanding need for a consistent level of detail, standardization of categories, and appropriate use of scales of compilation for a type of data frequently used by land use planners, land managers, resource management planners, and others.
