The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257224.
| Value | Definition |
|---|---|
| 1 Unclassified | This class contains nodata 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 mostlyvegetation in the form of lawn grasses. Impervious surfaces account forless than 20 percent of total cover. These areas most commonly includelarge-lot single-family housing units, parks, golf courses, and vegetationplanted in developed settings for recreation, erosion control, oraesthetic 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 mixturesplanted for livestock grazing or the production of sees orhay crops. |
| 8 Grassland | Dominated by naturally occurring grasses and non-grasses(forbs) that are not fertilized, cut, tilled, or plantedregularly. |
| 9 Deciduous Forest | Includes areas dominated by single stemmed, woodyvegetation un-branched 0.6 to 1 meter (2 to 3 feet) abovethe ground and having a height greater than 5 meters (20feet). |
| 10 Evergreen Forest | Includes areas in which more than 67 percent of the treesremain green throughout the year. Both coniferous andbroad-leaved evergreens (greater than 5 meters) areincluded in this category. |
| 11 Mixed Forest | Contains all forested areas in which both evergreen anddeciduous trees (greater than 5 meters) are growing andneither predominate. |
| 12 Scrub/Shrub | Areas dominated by woody vegetation less than 5 meters inheight. This class includes true shrubs, young trees, andtrees or shrubs that are small or stunted because ofenvironmental conditions. |
| 13 Palustrine Forested Wetland | Includes all non-tidal wetlands dominated by woodyvegetation greater than or equal to 5 meters in height,and all such wetlands that occur in tidal areas in whichsalinity due to ocean-derived salts is below 0.5 parts perthousand (ppt). |
| 14 Palustrine Scrub/Shrub Wetland | Includes all non-tidal wetlands dominated by woodyvegetation less than or equal to 5 meters in height, andall such wetlands that occur in tidal areas in whichsalinity 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 allsuch wetlands that occur in tidal areas in which salinitydue to ocean- derived salts is below 0.5 ppt. |
| 16 Estuarine Forest Wetland | Includes all tidal wetlands dominated by woody vegetationgreater than or equal to 5 meters in height, and all suchwetlands that occur in tidal areas in which salinity dueto ocean-derived salts is above 0.5 parts per thousand(ppt). |
| 17 Estuarine Scrub/Shrub Wetland | Includes all tidal wetlands dominated by woody vegetationless than 5 meters in height, and all suchwetlands that occur in tidal areas in which salinity dueto 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 mostof the growing season in most years. Perennial plantsusually dominate these wetlands. All water regimes areincluded except those that are sub-tidal and irregularlyexposed. |
| 19 Unconsolidated Shore | Characterized by substrates lacking vegetation except forpioneering plants that become established during briefperiods when growing conditions are favorable. Erosion anddeposition by waves and currents produce a number oflandforms, such as beaches, bars, and flats, all of whichare included in this class. |
| 20 Bare Land | Composed of bare soil, rock, sand, silt, gravel, or otherearthen material with little or no vegetation. |
| 21 Water | Includes all areas of open water with less than 30 percentcover of trees, shrubs, persistent emergent plants,emergent mosses, or lichens. |
| 22 Palustrine Aquatic Bed | Includes wetlands and deepwater habitats dominated byplants that grow principally on or below the surface ofthe water for most of the growing season in most years. |
| 23 Estuarine Aquatic Bed | Includes widespread and diverse Algal Beds in the Marineand Estuarine Systems, where they occupy substratescharacterized by a wide range of sediment depths andtextures. They occur in both the sub-tidal and inter-tidalSubsystems and may grow to depths of 30 m (98 feet).This class includes kelp forests. |
| 24 Tundra | Includes treeless cover beyond the latitudinal limit ofthe boreal forest in pole-ward regions and above theelevation range of the boreal forest in high mountains. |
| 25 Snow/Ice | Includes persistent snow and ice that persist for greaterportions 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 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.
