48292 2009_era_as_rose_atoll_landcover Data Set Published / External 47841 C-CAP Project Completed 2013-08-15 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 1 full or partial 2009 WorldView2 multispectral scene and the 2002 high-resolution Rose Atoll, American Samoa C-CAP data set. The imagery and base classification were included in a multi-step change detection process to extract land cover features in the 2009 imagery. To improve the understanding of coastal uplands and wetlands, and their linkages with the distribution, abundance, and health of living marine resources. 11513 Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > LAND SURFACE > LAND USE/LAND COVER Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > LAND SURFACE > LAND USE/LAND COVER > LAND USE/LAND COVER CLASSIFICATION Theme ISO 19115 Topic Category imageryBaseMapsEarthCover Spatial Global Change Master Directory (GCMD) Location Keywords OCEAN > PACIFIC OCEAN > CENTRAL PACIFIC OCEAN > AMERICAN SAMOA Instrument Global Change Master Directory (GCMD) Instrument Keywords CAMERAS Platform Global Change Master Directory (GCMD) Platform Keywords Airplane > Airplane Platform Global Change Master Directory (GCMD) Platform Keywords WORLDVIEW-2 > DigitalGlobe WORLDVIEW-2 Platform Global Change Master Directory (GCMD) Platform Keywords WORLDVIEW-3 > DigitalGlobe WORLDVIEW-3 Theme Land Cover Theme Land Cover Analysis Theme Remotely Sensed Imagery/Photos Spatial Coastal Zone Spatial Rose Atoll Office for Coastal Management Charleston SC Data Set 5 years Image (digital) Users must assume responsibility to determine the usability of these data. 49009 Layer_1 Published / External Completed Rose Atoll, American Samoa delineated by a WorldView2 Scene collected December 6, 2009. | Description Source: unknown Converted from FGDC using 'fgdc_to_inport_xml_entity.pl' script. 1 Value VARCHAR No No Active 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 c Data Steward 2013-08-15 Organization NOAA Office for Coastal Management NOAA/OCM coastal.info@noaa.gov 2234 South Hobson Ave Charleston SC 29405-2413 (843) 740-1202 https://coast.noaa.gov NOAA Office for Coastal Management Home Page Online Resource Distributor 2013-08-15 Organization NOAA Office for Coastal Management NOAA/OCM coastal.info@noaa.gov 2234 South Hobson Ave Charleston SC 29405-2413 (843) 740-1202 https://coast.noaa.gov NOAA Office for Coastal Management Home Page Online Resource Metadata Contact 2013-08-15 Organization NOAA Office for Coastal Management NOAA/OCM coastal.info@noaa.gov 2234 South Hobson Ave Charleston SC 29405-2413 (843) 740-1202 https://coast.noaa.gov NOAA Office for Coastal Management Home Page Online Resource Point of Contact 2013-08-15 Organization NOAA Office for Coastal Management NOAA/OCM coastal.info@noaa.gov 2234 South Hobson Ave Charleston SC 29405-2413 (843) 740-1202 https://coast.noaa.gov NOAA Office for Coastal Management Home Page Online Resource Acquisition date of the WorldView2 Scene -168.103706 -168.074981 -14.313686 -14.335825 Discrete 2009-12-06 Yes 3 Point No Row 1838 Column 2065 Vertical 1 Unclassified None Data set is not for use in litigation.

(www.photoscience.com). This version of the classification is the High Resolution Land Cover (2009-era) for Rose Atoll, American Samoa. This section outlines the classification procedure for Rose Atoll, American Samoa High Resolution C-CAP. 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 imagery utilized for this project was provided from Digital Globe as an orthorectified, georeferenced product. Photo Science geo-referenced the 2002 C-CAP classification and the 2002 base imagery to the WorldView2 (as it has better horizontal accuracy) to co-register the data sets. Classification: The 2002 C-CAP classification was overlaid on the 2009 WorldView2 imagery with a semi-transparency. The classification was systematically reviewed at a scale of 1:2,500. Where land cover changes were identified the analyst would zoom into a larger scale and manually edit the map to reflect the 2009 ground conditions. The updated map then went through an independent review to further refine the classification. Image segmentation was run on the 2009 imagery in a buffered zone around all of the changed areas. The updated land cover was summarized by the image objects (segments) to replace hand delineated boundaries with boundaries based on image segmentation. This final step ensured a consistent look and feel across the high resolution C-CAP data sets.
