This data set consists of land cover 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 CIR imagery captured from Microsoft UltraCAM X (2010-11 flights) and Z/I Imaging DMC-II 230 (2012 flights) digital sensors. The land cover is based on the 2007 high resolution St. Thomas C-CAP dataset. Changes were identified using aerial photo interpretation of the 2007 dataset against the 2010-2012 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

There was no terrain correction in the geo-referencing procedure.
Data does not exist for all classes.
There are no pixels representing class 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.

This data set was created by Dewberry (www.dewberry.com). This version of the classification is the High Resolution Land Cover (2012-era) for the Island of St Thomas, United States Virgin Islands.
This section outlines the classification procedure for the St. Thomas High Resolution C-CAP. The color-infrared imagery used in producing this land cover product was also utilized in producing an associated impervious surfaces layer for the island. This land cover is based on the 2007 high resolution St. Thomas C-CAP dataset. Changes were identified using aerial photo interpretation of the 2007 dataset against the 2010-2012 imagery. 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 2010-2012 color-infrared imagery utilized for this project was provided from the USACE as an orthorectified, georeferenced product. The imagery was reviewed for radiometric errors, pixel dropouts, and other image issues. Individual image tiles were merged into a single mosaic and re-sampled from the native 1-foot spatial resolution to 1m.
Classification:
The 2007 C-CAP dataset was over-laid with semi-transparency on the 2010-2012 color-infrared imagery. It was panned at a scale of 1:5,000 and manually updated to match features in the 2010-2012 imagery. 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.
Map Finalization - Dewberry used independent reviewer's comments to further refine the land cover map.
