This dataset was created to define the ammount of 'vegetative' land cover within Louisiana's watersheds.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Land Cover Classifications dataset is a 30 meter pixel raster that classifies all land cover within Louisiana's watersheds into Vegetation, Agriculture, Developed or Water classes. This is a reclassification of the U.S.G.S National Land Cover Dataset (NLCD) from 36 classes in the original dataset to 4. This makes it easier to determine the ratio of vegetative cover to developed land and agricultural land within a watershed.</SPAN></P></DIV></DIV></DIV>

National Land Cover Dataset (NLCD) Area 9 which consists of zones 38, 42, 43 and 44, Area 10 which consists of zones 32, 35, 36, 37a and 37b, and Area 12 which consists of 37b, 45, 46a, 46b and 48 were merged into a single dataset. The merged dataset was then clipped to the boundaries of the 57 U.S.G,S. 8 Digit Hydrologic Units that are within Louisiana. The clipped dataset was reclassified into Vegetation, Agriculture, Developed, and water classes. Vegetation includes land areas classified as: barren land, deciduous forest, evergreen forest, mixed forest, shrub/scrub, grassland/herbaceous, woody wetlands and emergent herbaceous wetlands. Agriculture includes land classified as pasture/hay and cultivated crops. Developed land category includes varying levels of actual development: low, medium and high intensity as well as open space. Water includes areas classified as open water. All processing was completed using ESRI ArcGIS 10.
The National Land Cover Database 2001 land cover layer was produced through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium. The MRLC Consortium is a partnership of federal agencies (www.mrlc.gov), consisting of the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), the U.S. Environmental Protection Agency (EPA), the U.S. Department of Agriculture (USDA), the U.S. Forest Service (USFS), the National Park Service (NPS), the U.S. Fish and Wildlife Service (FWS), the Bureau of Land Management (BLM) and the USDA Natural Resources Conservation Service (NRCS). One of the primary goals of the project is to generate a current, consistent, seamless, and accurate National Land cover Database (NLCD) circa 2001 for the United States at medium spatial resolution. This landcover map and all documents pertaining to it are considered "provisional" until a formal accuracy assessment can be conducted. For a detailed definition and discussion on MRLC and the NLCD 2001 products, refer to Homer et al. (2004) and http://www.mrlc.gov/mrlc2k.asp.
