This data set consists of land derived from high resolution imagery and was analyzed according to the Coastal Change Analysis Program (C-CAP) protocol to determine land cover. This data set utilized 35 full or partial WorldView2 multispectral scenes and the 2005 high-resolution Kauai C-CAP data set. The imagery and base classification were included in a multi-step semi-automated change detection process to extract land cover features in the 2010 imagery.
To improve the understanding of coastal uplands and wetlands, and their linkages with the distribution, abundance, and health of living marine resources.

Landcover Classification as determined by NOAA Coastal Change Analysis Program (C-CAP) | Description Source: NOAA Office for Coastal Management High-Resolution Land Cover Project
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

This data set was created by Photo Science (www.photoscience.com). This version of the classification is the High Resolution Land Cover (2010-era) for Kauai, Hawaii.
This section outlines the classification procedure for the Kauai High Resolution C-CAP. WorldView2 imagery used in producing this land cover product was also utilized in producing an associated impervious surfaces layer for the island. The mapping approach utilized a boundary summary, outlier change detection process and refinement procedure developed by Photo Science to leverage the 2005 high resolution C-CAP data set to create the 2010 high resolution C-CAP. A calibration visit was not conducted though NOAA had access to local resources for validation. Non impervious features were mapped using a 0.25 acre minimum mapping unit (MMU) and impervious features were mapped using a 0.1 acre MMU.
Pre-processing steps:
The WorldView2 mosaic utilized for this project was provided from Digital Globe as an orthorectified, georeferenced product. Multiple image primitives and indicies such as texture and NDVI were derived from the 8-band satellite data. The imagery was re-sampled from it's native 2m spatial resolution to 2.4m. The 2005 C-CAP classification and the base Quickbird imagery (used in the original mapping) were geometrically corrected to co-register to the WorldView2 data which has a higher geolocation accuracy.
Impervious Update:
The 2005 impervious was over-laid with semi-transparency on the 2010 satellite data. It was panned at a scale of 1:3,500 and manually updated to match the 2010 data. Analysts zoomed in to a larger scale when necessary to perform edits. The product went through a QC procedure to ensure features were accurately captured.
Segmentation and Outlier Detection Process:
The 2010 impervious was combined with the 2005 land cover to create a hybrid data set. Image segmentation, done in Trimble's eCognition software, was completed at multiple scales using the multispectral (2.4 m) imagery in order to group like spectral and textural objects within the imagery. For consistency, the associated hybrid data set was incorporated into the segmentation layer as a boundary delimiter. Segments contained image attributes and a label from the 2005 classification. These data were inputs to a custom multi-variate outlier detection tool that identified objects of potential change. These areas created the change mask.
Training Site Data:
Training data was photo interpreted and collected within the change mask and was super-sampled from features outside of the mask. The referenced data set went through a QA/QC procedure to ensure it met accuracy standards.
Classification:
Automated Classification - Image segments were classified using a decision tree classifier in Rulequest's See5 software based on the training data and image attributes.
Automated Classification Refinement - Models are built to refine or reclassify land cover areas by utilizing the wealth of attribute information linked to each segment within eCognition.
Classification Edits - As with any automated or semi-automated land cover classification there are often inconsistencies in the land cover map. The final step before map finalization was to remove inaccuracies through manual segment labeling as interpreted by an analyst.
Map Finalization - Photo Science used independent reviewer's comments to further refine the land cover map.
