{ "currentVersion": 10.3, "serviceDescription": "These data can be used in a geographic information system (GIS) for any\nnumber of purposes such as assessing wildlife habitat, water quality, pesticide\nrunoff, land use change, etc. The state data sets are provided with a 300 meter\nbuffer beyond the State border to faciliate combining the State files into larger\nregions.\n\nThe user must have a firm understanding of how the datasets were compiled and the\nresulting limitations of these data. The National Land Cover Dataset was compiled\nfrom Landsat satellite TM imagery (circa 1992) with a spatial resolution of 30\nmeters and supplemented by various ancillary data (where available). The analysis\nand interpretation of the satellite imagery was conducted using very large,\nsometimes multi-state image mosaics (i.e. up to 18 Landsat scenes). Using a\nrelatively small number of aerial photographs for 'ground truth', the thematic\ninterpretations were necessarily conducted from a spatially-broad perspective.\nFurthermore, the accuracy assessments (see below) correspond to 'federal regions'\nwhich are groupings of contiguous States. Thus, the reliability of the data is\ngreatest at the State or multi-State level. The statistical accuracy of the data\nis known only for the region.\n\nImportant Caution Advisory\n\nWith this in mind, users are cautioned to carefully scrutinize the data to\nsee if they are of sufficient reliability before attempting to use the\ndataset for larger-scale or local analyses. This evaluation must be made\nremembering that the NLCD represents conditions in the early 1990s.\n\nThe Georgia portion of the NLCD was created as part of land cover\nmapping activities for Federal Region IV that includes the States of\nSouth Carolina, Florida, Alabama, Mississippi, North Carolina, Kentucky,\nand Tennessee. The NLCD classification contains 21 different land\ncover categories with a spatial resolution of 30 meters. The NLCD was\nproduced as a cooperative effort between the U.S. Geological Survey\n(USGS) and the U.S. Environmental Protection Agency (US EPA) to produce\na consistent, land cover data layer for the conterminous U.S. using\nearly 1990s Landsat thematic mapper (TM) data purchased by the Multi-\nresolution Land Characterization (MRLC) Consortium.
