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 ope

There was no terrain correction in the geo-referencing procedure.
Data does not exist for all classes.
There are no pixels representing class 9 (Deciduous Forest), 11 (Mixed Forest), 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 dataset was created by Sanborn (www.sanborn.com).
This version of the classification is the High Resolution Land Cover (2005-era) for the Island of Pagan, CNMI.
This section outlines the classification procedure for the Island of Pagan, CNMI High Resolution C-CAP. This island has no man-made impervious surfaces, thus an impervious layer was not created. The mapping approach utilized a boundary summary and refinement procedure developed by Sanborn to leverage previous United States Forest Service mapping efforts to create the high resolution land cover data set. A calibration visit was conducted and training data was collected for classification. Non impervious features were mapped using a 0.5 acre minimum mapping unit (MMU).
Pre-processing steps:
The Quickbird mosaic utilized for this project was provided from Digital Globe as an orthorectifed, georeferenced product and was consistent with the quoted 1:12000 spatial accuracy.
Field-Collected Data:
Training data was collected in the field between March 14th and 27th, 2008. Land cover observations were recorded by analysts. The referenced dataset went through a QA/QC procedure to ensure it met accuracy standards.
Classification:
Segmentation - Image segmentation 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 impervious data set was incorporated into the segmentation layer as a boundary delimiter. Segments can share boundaries of an impervious surface, but can never overlap an impervious surface.
Automated Classification, Image segments are classified using a decision tree classifier in See5 software and an iterative nearest neighbor classifier in Definiens software. Nearest neighbor training data is collected through analyst interpretation or ancillary data sets and used to calibrate the classification algorithm.
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 Definiens.
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 - Sanborn used independent reviewer's comments to further refine the land cover map.
