USGS 2005 GAP Landcover

The raster geographic data layer described by this document is documented more fully in the final report produced from North Dakota Gap Analysis.

A vegetation and land cover map for North Dakota was created as part of the North Dakota Gap Analysis Project for the U. S. Geological Survey's National Gap Analysis Program. Vegetation and land cover was mapped from a multi-temporal analysis of May, July, and September Landsat Thematic Mapper images acquired from August 1992 to September 1998. Natural and semi-natural vegetation categories are cross-walked and described with reference to the National Vegetation Classification System. Digital National Wetland Inventory data produced by the U.S. Fish and Wildlife Service was used in mapping wetlands.

he goal of the National Gap Analysis program is to improve biodiversity policy and planning by making digital maps and associated databases for vegetation and land cover, vertebrate species distribution, and land stewardship available to decision makers. Gap Analysis uses digital maps in the geographic information system overlay process to describe the distribution of vegetation and land cover types and vertebrate species relative to the distribution of public lands and their management objectives. The vegetation and land cover map is a driving variable in the production of potential distribution maps for terrestrial vertebrates. Terrestrial vertebrate species and natural vegetation land cover types not "adequately represented" on public lands are identified as "gaps" in existing conservation efforts.

The data provide a coarse generalized abstraction of the geographic distribution of land cover circa 1998 for North Dakota. These data were produced for an intended application at the state and at the national scale by aggregation of the data with GAP analysis products from other states. These data may not be appropriate for local or large-scale analyses (>1:100,000 scale). Notification of the use of the data and acknowledgement of the U.S. Geological Survey would be appreciated in products derived from the use of the data.
