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. This dataset was created by NOAA's Ocean Service, Office for Coastal Management (OCM). This dataset contains the classifications of 2004 imagery and 2016 imagery. It is used for change analysis between these years. The attributes include a from-to change description category. There are 481 classes corresponding to the 481 possible from-to change combinations. In this section of the metadata, the 2005 classification procedure is described, then the 2016 change detection classification procedure is described. Finally in the post-processing section, the process of combining the maps to generate a spatial matrix of change is discussed. Early Date (2005) Classification: This dataset was created by Sanborn (www.sanborn.com). This version of the classification is the High Resolution Land Cover (2005-era) for the Territory of Guam. This section outlines the classification procedure for the Asuncion Island, 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. 2019-07-30T00:00:00 Map Finalization - Sanborn used independent reviewer's comments to further refine the land cover map.

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 2004 NOAA Asuncion C-CAP land cover product. Classification- The image segements from the 2016 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 Post-Processing Steps: A GIS matrix algorithm was run with 2004 and 2016 datasets as inputs. The algorithm generates a from-to file where each combination is uniquely labeled from 1 to 481. 2019-07-30T00:00:00
