| Value | Definition |
|---|---|
| 1 Unclassified | This class contains no data due to cloud conditions or data voids. |
| 2 High Intensity Developed | Contains little or no vegetation. Includes highly developed areas where people reside or work in high numbers. Examples include apartment complexes, row houses and commercial/industrial. Impervious surfaces account for 80 to 100 percent of the total cover. |
| 3 Medium Intensity Developed | Contains substantial amounts of constructed surface mixed with substantial amounts of vegetated surface. Includes areas with a mixture of constructed materials and vegetation. Impervious surfaces account for 50-79 percent of the total cover. These areas most commonly include single-family housing units. |
| 4 Low Intensity Developed | Contains substantial amounts of constructed surface mixed with substantial amounts of vegetated surface. Includes areas with a mixture of constructed materials and vegetation. Impervious surfaces account for 20-49 percent of total cover. These areas most commonly include single-family housing units. |
| 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 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 | 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. |

Imaging, Space, 20041001, C-CAP Classification for Washington Coastal Zone, Early-Date: NOAA Coastal Services Center, Charleston SC.Online Links:
Pre-processing steps: Each Landsat TM scene was geo-referenced by USGS (United States Geological Survey) EROS Data Center. The Space Imaging staff reviewed the spectral and spatial quality of the imagery. Areas that were greater than 1-2 pixels off were sent back to USGS for reprocessing. The data was geo-referenced to Albers Conical Equal Area, with a spheroid of GRS 1980, and Datum of WGS84.
While the accuracy of a 1995-era classification is hard to determine based on 2000-era ground truth, the 1995-era classification is composed of approximately 95.5% of the final 2000-era classification. This is because only the areas of change between 1995 and 2000 were classified for the early-date classification. Then the classified early-date layer was overlaid onto the late-date classification. Therefore the accuracy assessment for the late-date classification is still a good estimate of the accuracy of the early-date classification.
According to accuracy assessment performed by Space Imaging, the overall accuracy is 86.1% and 85.0% Kappa. The accuracy results shown below are from a combined accuracy completed on both Oregon and Washington
