    ValueDefinition
    1 UnclassifiedThis class contains no data due to cloud conditions or data voids.
    2 High Intensity DevelopedContains 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 DevelopedContains 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 DevelopedContains 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 DevelopedIncludes 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 LandIncludes herbaceous (cropland) and woody (e.g., orchards, nurseries, and vineyards) cultivated lands.
    7 Pasture/Haycharacterized by grasses, legumes or grass-legumes mixtures planted for livestock grazing or the production of sees or hay crops.
    8 GrasslandDominated by naturally occurring grasses and non-grasses (forbs) that are not fertilized, cut, tilled, or planted regularly.
    9 Deciduous ForestIncludes 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 ForestIncludes 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 ForestContains all forested areas in which both evergreen and deciduous trees (greater than 5 meters) are growing and neither predominate.
    12 Scrub/ShrubAreas 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 WetlandIncludes 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 WetlandIncludes 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 WetlandIncludes 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 WetlandIncludes 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 WetlandIncludes 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 EmergentCharacterized 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 ShoreCharacterized 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 LandComposed of bare soil, rock, sand, silt, gravel, or other earthen material with little or no vegetation.
    21 WaterIncludes all areas of open water with less than 30 percent cover of trees, shrubs, persistent emergent plants, emergent mosses, or lichens.
    22 Palustrine Aquatic BedIncludes 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 BedIncludes 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 TundraIncludes 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/IceIncludes persistent snow and ice that persist for greater portions of the year.

  3. To whom should users address questions about the data?


Why was the data set created?

To improve the understanding of coastal uplands and wetlands, and their linkages with the distribution, abundance, and health of living marine resources.


How was the data set created?

  1. From what previous works were the data drawn?

  2. How were the data generated, processed, and modified?

    (process 1 of 1)
    This dataset was created by Space Imaging. This version of the classification is the early-date (1995-era). The study area is the Coastal Washington Region. A late-date (2000-era) classification is also available for the same area. This section outlines the classification procedure for the Washington C-CAP.
    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.

  3. What similar or related data should the user be aware of?


How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    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

  2. How accurate are the geographic locations?
