The probability rating which covers landcover mapping provides a continuum of wetness from dry to water. The layer is not a wetland classification but provides the wetland likelihood at a specific location. The rating was developed through a modelling process combining multiple GIS and remote sensing data sets including soil characteristics, elevation, existing wetland inventories, hydrographical extents and satellite imagery . Data available via download from the Digital Coast, either from customizable download in NOAA's Digital Access Viewer or FTP download by regions. To inform likelihood of wetland and assess areas for potential mitigation or restoration. 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 asNeeded EARTH SCIENCE > HUMAN DIMENSIONS > ENVIRONMENTAL GOVERNANCE/MANAGEMENT > LAND MANAGEMENT > LAND USE/LAND COVER CLASSIFICATION EARTH SCIENCE > LAND SURFACE > LAND USE/LAND COVER EARTH SCIENCE > LAND SURFACE > LAND USE/LAND COVER > LAND USE CLASSES EARTH SCIENCE > LAND SURFACE > LAND USE/LAND COVER > LAND USE/LAND COVER CLASSIFICATION theme Global Change Master Directory (GCMD) Science Keywords 17.0 CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > ALABAMA CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > CALIFORNIA CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > CONNECTICUT CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > DELAWARE CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > DISTRICT OF COLUMBIA CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > FLORIDA CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > GEORGIA CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > ILLINOIS CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > INDIANA CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > LOUISIANA CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > MAINE CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > MARYLAND CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > MASSACHUSETTS CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > MICHIGAN CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > MINNESOTA CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > MISSISSIPPI CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > NEW HAMPSHIRE CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > NEW JERSEY CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > NEW YORK CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > NORTH CAROLINA CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > OHIO CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > OREGON CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > PENNSYLVANIA CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > RHODE ISLAND CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > SOUTH CAROLINA CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > TEXAS CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > VERMONT CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > VIRGINIA CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > WASHINGTON CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > WISCONSIN place Global Change Master Directory (GCMD) Location Keywords 20.8 CAMERAS instrument Global Change Master Directory (GCMD) Instrument Keywords 17.2 LANDSAT > LANDSAT platform Global Change Master Directory (GCMD) Platform Keywords 17.2 CCAP Coastal Change Analysis Program Land Cover Analysis Remotely Sensed Imagery/Photos Wetlands theme Alabama California Connecticut Delaware Florida Georgia Illinois Indiana Louisiana Maine Maryland Massachusetts Michigan Minnesota Mississippi New Hampshire New Jersey New York North Carolina Ohio Oregon Pennsylvania Rhode Island South Carolina Texas U.S. U.S. Coastal Zone United States Vermont Virginia Washington Washington DC Wisconsin 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.

Horizontal Positional Accuracy Landsat scenes were geo-referenced by Eros Data Center. Vertical Positional Accuracy There was no terrain correction in the geo-referencing procedure. Input data were not altered before pre-processing. Completeness Report All pixels have been classified as designated by the model parameters. 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. Data Collection: This involved the acquisition of pre-existing data sets to be used in the creation of the probability rating. These data were all sourced from national geospatial programs and most were available at no charge. The input data sets and their sources are: National Wetlands Inventory (NWI) from US Fisheries and Wildlife, National Hydrology Data set (NHD) from USGS, Soil Survey Geographic Database (SSURGO) from Natural Resource Conservation Service, 30m National Elevation Data set (NED) from USGS, and satellite imagery (Landsat, but 2009 NAIP imagery for state of Washington). Where available, wetland maps from County GIS Departments were used for validation. 2010-03-01T00:00:00 Pre-process data: Each data sets mentioned above was preprocessed in preparation for the comprehensive modelling step (see the last process step). This included converting vector data (NWI and NHD areas & flowlines) into the ERDAS IMAGINE raster format and resampling to a 30m spatial resolution. The SSURGO data was processed to create a percent hydric soils layer ranging from 0-100. Additionally, a slope and curvature models were derived from the 30m NED. Cloud free Landsat 7 TM scenes were acquired for each regional project. The Hydric Soils and NHD raster were then modelled based on topographic characteristics to remove areas that did not support wetlands such as areas with high slopes and convexity. The NWI rasterized polygons were recoded to give each class a rating with a higher rating designated to the Woody wetland classes. The resulting raster layers from these preprocesing steps provided the building blocks for the probability rating. 2010-03-01T00:00:00 The final step was to generate a comprehensive probability rating that combined information from the various modelled layers. Multiple models were constructed that weighted the NWI rasterized polygons and linear data, Topo modelled Soils, Topo modelled NHD Polygons and Topo modelled image segments that intersected with NHD flowlines. No single model was developed to combine all of the processed data; instead, many models were developed that contributed to the final rating. As a result, based on the combination of: inclusion in the NWI, percentage of hydric soils and location in the floodplain a layer was generated with values ranging from 0 (Unlikely) to 8 (highly likely). Areas of open water were designated as 10. 2014-04-23T00:00:00 Source Contribution: Wetland Potential Layers were used to find the likelihood of wetland potential and assess areas for potential mitigation or restoration. | Source Geospatial Form: raster digital data | Type of Source Media: Downloadable NOAA Coastal Change Analysis Program (C-CAP) National Wetland Probability 2014-11-10 publication Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Office for Coastal Management (OCM) https://coast.noaa.gov/dataviewer/#/imagery/search/where:ID=4708 WWW:LINK-1.0-http--link Source Citation URL Source Citation URL information 1977-01-01 2010-12-31
