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 2010-10-06 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 2010-10-06 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 2010-10-06 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 2010-10-06 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 aerial photographs. 145.688029 145.831972 15.290656 15.091067 Discrete 1945-05-09 Yes 3 Point No Row 7670 Column 10997 Vertical 1 Unclassified None Data set is not for use in litigation.

Data does not exist for all classes. There are no pixels representing class 7 (Pasture/Hay), 9 (Deciduous Forest), 11 (Mixed Forest), 16 (Estuarine Forested Wetland), 17 (Estuarine Scrub/Shrub Wetland), 18 (Estuarine Emergent Wetland), 19 (Unconsolidated Shore), 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 version of the classification is the High Resolution Land Cover (1945-era) for the Island of Saipan , CNMI. This section outlines the classification procedure for the Island of Saipan , CNMI High Resolution C-CAP. Scanned historic black-and-white images from 1945 were used in a semi-automated methodology to detect change (retroactive) from 2005 QuickBird imagery. The mapping approach used image segments derived from the mosaicked 1945 imagery and the 2005 land cover classification which were analyzed and categorized as changed/not changed. Once changes were identified, they were modeled into the 2005 classification to create the 1945 classification. Pervious features were mapped using a 0.5 acre minimum mapping unit (MMU), excepting some small features of historic interest. Pre-processing steps: The historic 1945 imagery was provided as scanned black-and-white unmosaicked tiffs. The tiffs were georectified using the 2005 QuickBird imagery as reference and subsequently mosaicked. Due to parallax problems with the high relief on the island, isolated shifts remained in the completed mosaics, which were accounted for in the subsequent steps. Classification: Segmentation - Image segmentation was completed at multiple scales using the 1945 mosaic, a texture band derived from the mosaic, and the 2005 land cover classification as a boundary layer. The segments were created using the MMU of 0.5 acre as an approximate minimum size threshold. Automated Classification - Image segments were classified using a decision tree classifier in See5 software into forested and non-forested categories only, using training data collected from the 1945 imagery and analyst interpretation. The result was then compared to and differenced with the 2005 land cover classification to provide a preliminary change mask. This was intended only as a broad guide to landscape changes Manual Change Interpretation and Classification - Analysts, using the preliminary change mask, scanned the imagery (both 1945 and 2005) for changes in the land cover. These changes were put into the change mask, with the segment often serving as land cover change boundaries. These boundaries were also manually changed where necessary. Those impervious surfaces that existed in 1945 but not in 2005 were edited in using raster editing methods. Once complete, the 1945 change mask was compared to/differenced with the 2005 classification to drop out any unchanged pixels. This left only those pixels and areas changed between 1945 and 2005. The change pixels were modeled into the 2005 classification to create the 1945 land cover classification. Map Finalization - Sanborn used independent reviewer's comments to further refine the land cover map.
