The NOAA Coastal Change Analysis Program (C-CAP) produces national standardized land cover and change products for the coastal regions of the U.S. C-CAP products inventory coastal intertidal areas, wetlands, and adjacent uplands with the goal of monitoring changes in these habitats through time. These maps are developed utilizing high resolution aerial imagery, primarily from the summer of 2021, along with lidar and various available ancillary information, and can be used to track changes in the landscape through time. This trend information gives important feedback to managers on the success or failure of management policies and programs and aid in developing a scientific understanding of the Earth system and its response to natural and human-induced changes. This understanding allows for the prediction of impacts due to these changes and the assessment of their cumulative effects, helping coastal resource managers make more informed regional decisions. C-CAP is dedicated to the development, distribution, and application of land cover and change data for the coastal regions of the U.S. completed NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information pointOfContact NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information custodian 5 years EARTH SCIENCE > LAND SURFACE > LAND USE/LAND COVER EARTH SCIENCE > LAND SURFACE > LAND USE/LAND COVER > LAND USE/LAND COVER CLASSIFICATION theme Global Change Master Directory (GCMD) Science Keywords 17.0 CAMERAS instrument Global Change Master Directory (GCMD) Instrument Keywords 17.2 Airplane > Airplane platform Global Change Master Directory (GCMD) Platform Keywords 17.2 Androscoggin Aroostook Cumberland Franklin Hancock Kennebec Knox Lincoln ME Maine Oxford Penobscot Piscataquis Sagadahoc Somerset Waldo Washington York place Geographic Names Information System C-CAP CCAP Land Cover Land Cover Analysis Remotely Sensed Imagery/Photos theme 2021 temporal Coastal Zone place DOC/NOAA/NOS/OCM > Office of Coastal Management, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

There were 914 total points distributed across the study area. The accuracy of each class is as follows (Producer's, User's accuracies): Impervious (92.7%, 94.4%) Impervious under Tree Canopy (66.7%, 100%) Open Space Developed (81.3%, 93.8%) Cultivated (94.3%, 84.6%) Pasture/Hay (95.9%, 86.2%) Grassland (59.2%, 86.5%) Upland Tree (Forest) (100%, 66.7%) Shrub/Scrub (75.0%, 78.1%) Palustrine Forested Wetland (87.5%, 87.5%) Palustrine Shrub/Scrub Wetland (86.6%, 89.2%) Palustrine Emergent Wetland (84.1%, 84.1%) Estuarine Forested Wetland (N/A, N/A) Estuarine Shrub/Scrub Wetland (N/A, N/A) Estuarine Emergent Wetland (100%, 100%) Unconsolidated Shore (93.5%, 97.7%) Bare Land (75.7%, 73.7%) Water (97.1%, 90.4%) Palustrine Aquatic Bed (64.7%, 68.8%) Estuarine Aquatic Bed (88.9%, 94.1%) Overall accuracy (85.6%) Points were sampled using a stratified random sampling scheme, with a minimum target sample of 20 points per class. A few of the rarer categories did not meet this minimum threshold or were not sampled at all due to the relatively low total area of those classes. Only the Palustrine Aquatic Bed and Estuarine Aquatic Bed categories had fewer than the target 20 point minimum, though several additional categories had relatively few sample locations, including: Estuarine Emergent Wetlands, Cultivated, and Impervious Under Canopy. Estuarine Scrub/Shrub Wetland and Estuarine Forested were not samples at all. The correct land cover classification was determined through analyst interpretation of the imagery used in creating the map, as well as possible references to Google Earth in order to reference additional dates/seasons of imagery for that location. All points were interpreted by two analysts, plus a third who made a final determination when there was disagreement on the call. This analysis allowed for the use of fuzzy designations, or alternate calls to the truth category where that truth call may not have been completely obvious, or where point locations are located so they could possibly be more than one category. Completeness Report Data does not exist for all classes. There are no pixels representing: class 1 (unclassified), class 9 (Deciduous Forest), 10 (Evergreen Forest), 25 (Perennial Ice/Snow). Deciduous and Evergreen trees were not differentiated. These features were mapped as either Mixed Forest, Palustrine Forested Wetlands, or Estuarine Forested Wetlands. 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 National Ocean Service (NOS), Office for Coastal Management (OCM). Classification: Initial 1m spatial resolution feature extraction for Impervious, Water, and Canopy (tree and scrub/shrub) mapping was conducted by Ecopia (https://www.ecopiatech.com/) using a proprietary feature recognition technology. This involves taking each image and classifying the pixels based on spectral and spatial properties, based on training examples and analyst refinement. This work was done under contract to NOAA, through NOAA”s Coastal Geospatial Services Contract (CGSC) vehicle. Impervious Surface Refinement: Commission and omission errors associated with the Impervious class were addressed through manual interpretation and clean up in ERDAS Imagine using OpenStreetMap road, building, and railroad layers as reference. Once the review and edits were complete, the refined Impervious class was incorporated back into the land cover data set. Water Refinement: Commission and omission errors associated with the Water class were addressed through manual interpretation and clean up in ERDAS Imagine. Once the review and edits were complete, the refined Water class was incorporated back into the land cover data set. Canopy Surface Refinement: Commission and omission errors associated with the Canopy class were addressed through manual interpretation and clean up in ERDAS Imagine. Once the review and edits were complete, the refined Canopy class was incorporated back into the land cover data set. Agriculture and Open Space Developed: Cultivated land, Pasture/Hay, and Open Space Developed features were incorporated into the grassland category of the initial land cover product based on available ancillary data. Commission and omission errors associated with these categories were addressed through manual interpretation and clean up in ERDAS Imagine. Once the review and edits were complete, the edits were incorporated back into the land cover data set. Wetlands: Wetlands were derived through a modeling process which used ancillary data such as Soils (SSURGO), the National Wetlands Inventory (NWI) and topographic derivatives (derived from USGS OPR data). Forest, shrub and grassland objects within the initial land cover that exhibited hydric characteristics based on the input ancillary layers were designated to their appropriate wetland category. The process relied mainly on the NWI to determine palustrine and estuarine distinctions. Grass and Bare: Grass and Bare classifications were derived using an NDVI threshold and manual interpretation. Refinement work was performed both by NOAA staff as well as NOAA’s CGSC contractor NV5 (https://www.nv5.com/). 2023-05-15T00:00:00 Attributes for this product are as follows: 0 Background 1 Unclassified 2 Developed Impervious 4 Developed Impervious under Tree Canopy 5 Developed, Open Space 6 Cultivated Crops 7 Pasture/Hay 8 Grassland/Herbaceous 11 Upland Tree (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 Aquatic Bed 23 Estuarine Aquatic Bed, 2023-05-15T00:00:00
