The GAP/LANDFIRE National Terrestrial Ecosystems represents a highly thematically detailed land cover map of the U.S. The GAP/LANDFIRE National Terrestrial Ecosystems dataset is produced by the U.S. Geological Survey in collaboration with the LANDFIRE Program. The GAP produces data and tools that help meet critical national challenges such as biodiversity conservation, renewable energy development, climate change adaptation, and infrastructure investment.

Southeast Gap Analysis Project, 1999–2001 These raster data have a 30 m x 30m cell resolution. (GAP/LANDFIRE National Terrestrial Ecosystems 2011 Summary Report: Florida, p. 6) Inappropriate Uses: It is far easier to identify appropriate uses than inappropriate ones, however, there is a "fuzzy line" that is eventually crossed when the differences in resolution of the data, size of geographic area being analyzed, and precision of the answer required for the question are no longer compatible. Examples include: - Using the 2001 and 2011 data to quantify change (see Data Use Constraints). -Using the data to map small areas (less than thousands of hectares), typically requiring mapping resolution at 1:24,000 scale and using aerial photographs or ground surveys. -Combining these data with other data finer than 1:100,000 scale to produce new hybrid maps or answer queries. -Generating specific areal measurements from the data finer than the nearest thousand hectares -Establishing exact boundaries for regulation or acquisition. -Establishing definite occurrence or non-occurrence of any feature for an exact geographic area -Determining abundance, health, or condition of any feature. -Establishing a measure of accuracy of any other data by comparison with GAP data. -Altering the data in any way and redistributing them as a GAP data product. -Using the data without acquiring and reviewing the metadata. (GAP_LANDFIRE_National_Terrestrial_Ecosystems_2011.xml) The digital land cover dataset may be used for various purposes with user's discretion. Specifically, this dataset was created for regional terrestrial biodiversity assessment. These data are not intended to be used at scales larger than 1:100,000.

The mission of the USGS Gap Analysis Program (GAP) is to provide state, regional and national biodiversity assessments of the conservation status of native vertebrate species and natural land cover types and to facilitate the application of this information to land management activities. The goal of GAP is to keep common species common by identifying species and plant communities not adequately represented in existing conservation lands. Common species are those not currently threatened with extinction. By providing these data, land managers and policy makers can make better-informed decisions when identifying priority areas for conservation. The U.S. Geological Survey National Gap Analysis Program Land Cover Data is complete for the conterminous United States. The national coverage has been clipped to each of the 50 states, the 21 Landscape Conservation Cooperatives and 6 regions.This data may represent one of these subsets.
