Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Coastal Services Center (CSC), 20070930, NOAA Coastal Change Analysis Program (CCAP) 1996-2001 Era Land Cover Change Data of the Southern United States: NOAA's Ocean Service, Coastal Services Center (CSC), Charleston, SC.
|1 Unclassified||This class contains no data due to cloud conditions or data voids.|
|2 High Intensity Developed||Contains little or no vegetation. This subclass includes heavily built-up urban centers as well as large constructed surfaces in suburban and rural areas. Large buildings (such as multiple family housing, hangars, and large barns), interstate highways, and runways typically fall into this subclass. Impervious surfaces account for 80-100 percent of the total cover.|
|3 Medium Intensity Developed||Contains substantial amounts of constructed surface mixed with substantial amounts of vegetated surface. Small buildings (such as single family housing, farm outbuildings, and large sheds), typically fall into this subclass. Impervious surfaces account for 50-79 percent of the total cover.|
|4 Low Intensity Developed||Contains constructed surface mixed with vegetated surface. This class includes features seen class 3, with the addition of streets and roads with associated trees and grasses. Impervious surfaces account for 21-49 percent of the total cover.|
|5 Developed Open Space||Includes areas with a mixture of some constructed materials, but mostly vegetation in the form of lawn grasses. This subclass includes parks, lawns, athletic fields, golf courses, and natural grasses occurring around airports and industrial sites. Impervious surfaces account for less than 20 percent of total cover.|
|6 Cultivated Land||Includes herbaceous (cropland) and woody (e.g., orchards, nurseries, and vineyards) cultivated lands.|
|7 Pasture/Hay||Characterized by grasses, legumes or grass-legume mixtures planted for livestock grazing or the production of seed or hay crops.|
|8 Grassland||Dominated by naturally occurring grasses and non-grasses (forbs) that are not fertilized, cut, tilled, or planted regularly.|
|9 Deciduous Forest||Includes areas dominated by single stemmed, woody vegetation unbranched 0.6 to 1 meter above the ground and having a height greater than 5 meters and cover more than 20% of land area. More than 75 percent of the tree species shed foliage simultaneous in response to seasonal change.|
|10 Evergreen Forest||Includes areas in which more than 67 percent of the trees remain green throughout the year. Both coniferous and broad-leaved evergreens are included in this category. Trees must be taller than 5 meters and more than 20% of the land cover.|
|11 Mixed Forest||Contains all forested areas in which both evergreen and deciduous trees are growing and neither predominate. Trees must be taller than 5 meters and more than 20% of the land cover.|
|12 Scrub/Shrub||Areas dominated by woody vegetation less than 5 meters in height. This class includes true shrubs,young trees, and trees or shrubs that are small or stunted because of environmental conditions. Includes both evergreen and deciduous scrub.|
|13 Palustrine Forested Wetland||Includes all non-tidal wetlands dominated by woody vegetation greater than or equal to 5 meters in height, and all such wetlands that occur in tidal areas in which salinity due to ocean-derived salts is below 0.5 parts per thousand (ppt).|
|14 Palustrine Scrub/Shrub Wetland||Includes all non-tidal wetlands dominated by woody vegetation less than or equal to 5 meters in height, and all such wetlands that occur in tidal areas in which salinity due to ocean-derived salts is below 0.5 ppt.|
|15 Palustrine Emergent Wetland||Includes all non-tidal wetlands dominated by persistent emergents, emergent mosses, or lichens, and all such wetlands that occur in tidal areas in which salinity due to ocean-derived salts is below 0.5 ppt.|
|16 Estuarine Forest Wetland||Includes all tidal wetlands dominated by woody vegetation greater than or equal to 5 meters in height, and all such wetlands that occur in tidal areas in which salinity due to ocean-derived salts is above 0.5 parts per thousand (ppt).|
|17 Estuarine Scrub/Shrub Wetland||Includes all tidal wetlands dominated by woody vegetation less than or equal to 5 meters in height, and all such wetlands that occur in tidal areas in which salinity due to ocean-derived salts is above 0.5 ppt.|
|18 Estuarine Emergent Wetland||Characterized by erect, rooted, herbaceous hydrophytes (excluding mosses and lichens) that are present for most of the growing season in most years. Perennial plants usually dominate these wetlands. All water regimes are included except those that are subtidal and irregularly exposed.|
|19 Unconsolidated Shore||Characterized by substrates lacking vegetation except for pioneering plants that become established during brief periods when growing conditions are favorable. Erosion and deposition by waves and currents produce a number of landforms, such as beaches, bars, and flats, all of which are included in this class.|
|20 Bare Land||Composed of bare soil, rock, sand, silt, gravel, or other earthen material with little or no vegetation.|
|21 Open Water||Includes all areas of open water with less than 25 percent cover of vegetation or soil.|
|22 Palustrine Aquatic Bed||Includes wetlands and deepwater habitats dominated by plants that grow principally on or below the surface of the water for most of the growing season in most years. Salinity due to ocean-derived salts is below 0.5 ppt.|
|23 Estuarine Aquatic Bed||Includes widespread and diverse Algal Beds in the Marine and Estuarine Systems, where they occupy substrates characterized by a wide range of sediment depths and textures. They occur in both the Subtidal and Intertidal Subsystems and may grow to depths of 30 m (98 feet). This includes kelp forests. Salinity due to ocean-derived salts is equal to or above 0.5 ppt.|
|24 Tundra||Includes treeless cover beyond the latitudinal limit of the boreal forest in pole-ward regions and above the elevation range of the boreal forest in high mountains.|
|25 Snow/Ice||Includes persistent snow and ice that persist for greater portions of the year.|

C-CAP is dedicated to the development, distribution, and application of land cover and change data for the coastal regions of the U.S. This effort is being conducted in close coordination with state coastal management agencies, the interagency Multi-Resolution Land Characteristics (MRLC) consortium, and the National Land Cover Database (NLCD) 2001 effort.
