The flattening of the ellipsoid used is 1/298.257224.
|1 Unclassified||This class contains no data due to cloud conditions or data voids.|
|2 Impervious Surfaces||Anthropogenic features such as buildings, parking lots and roads developed from asphalt, concrete or other constructed surfaces which do not allow infiltration from precipitation.|
|5 Open Spaces Developed||Includes areas with a mixture of some constructed materials, but mostly vegetation in the form of lawn grasses. Impervious surfaces account for less than 20 percent of total cover. These areas most commonly include large-lot single-family housing units, parks, golf courses, and vegetation planted in developed settings for recreation, erosion control, or aesthetic purposes.|
|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-legumes mixtures planted for livestock grazing or the production of sees 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 un-branched 0.6 to 1 meter (2 to 3 feet) above the ground and having a height greater than 5 meters (20 feet).|
|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 (greater than 5 meters) are included in this category.|
|11 Mixed Forest||Contains all forested areas in which both evergreen and deciduous trees (greater than 5 meters) are growing and neither predominate.|
|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.|
|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 trees, shrubs, 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 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||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 sub-tidal 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 Water||Includes all areas of open water with less than 30 percent cover of trees, shrubs, persistent emergent plants, emergent mosses, or lichens.|
|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.|
|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 sub-tidal and inter-tidal Subsystems and may grow to depths of 30 m (98 feet). This class includes kelp forests.|
|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.|
To create a baseline inventory of land cover features which can be utilized by state and local resource managers.

There was no terrain correction in the geo-referencing procedure.
Data does not exist for all classes. There are no pixels representing classes 6 (Cultivated Crops), 7 (Pasture/Hay) 11 (Mixed Forest), 22 (Palustrine Aquatic Bed), 23 (Estuarine Aquatic Bed), 24 (Tundra), 25 (Perennial Ice/Snow), 26 (Dwarf Scrub - Alaska specific class), 27 (Sedge/Herbaceous), and 28 (Moss - Alaska specific). Developed classes have been altered to exclude the percentage breakdown of impervious surfaces as the breakdown is not appropriate for high resolution mapping (Developed High Intensity (2), Developed Medium Intensity (3), and Developed Low Intensity (4) are reduced to Impervious (Class 2)).
Tests for logical consistency indicate that all row and column positions in the selected latitude/longitude window contain data. Conversion and integration with vector files indicates that all positions are consistent with earth coordinates covering the same area. Attribute files are logically consistent.
