| * » Abstract |
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 a Worldview-2 multispectral scene dated 02-02-2015. |
| * Purpose |
To create a baseline inventory of land cover features which can be utilized by state and local resource managers. |

| Completeness Report |
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)). |
| Conceptual Consistency |
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. |

| » Description |
This dataset was created by NOAA's Ocean Service, Office for Coastal Management (OCM). This version of the classification is the High Resolution Land Cover (2015-era) for the Island of Alamagan, CNMI. This section outlines the classification procedure for the Island of Alamagan, CNMI High Resolution C-CAP. Non impervious features were mapped using a 0.5 acre minimum mapping unit (MMU). Pre-processing steps: The Worldview-2 mosaic utilized for this project was provided from United States Department of Agriculture, Natural Resources Conservation Service as an orthorectifed, georeferenced product. 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 with previous land cover mapping efforts, the generation of objects was partially constrained by the 2007 NOAA Alamagan C-CAP land cover product. Classification- The image segements from the 2015 Worldview-2 imagery were overlaid on imagery and analysts counducted a visual analysis to identify areas of change. Map Finalization - NOAA OCM performed two rounds of internal product review. Reviewer comments were incorporated to further refine the final land cover product. Attributes for this product are as follows: 0 Background 1 Unclassified 2 Impervious 3 4 5 Developed, Open Space 6 Cultivated Crops 7 Pasture/Hay 8 Grassland/Herbaceous 9 Deciduous Forest 10 Evergreen Forest 11 Mixed Forest 12 Scrub/Shrub 13 Palustrine Forested Wetland 14 Palustrine Scrub/Shrub Wetland 15 Palustrine Emergent Wetland 16 Estuarine Forested Wetland 17 Estuarine Scrub/Shrub Wetland 18 Estuarine Emergent Wetland 19 Unconsolidated Shore 20 Bare Land 21 Open Water 22 Palustrine Acquatic Bed |
