Coastal Change Analysis Program(C‐CAP)
Office of Ocean and Coastal Resource Management | Coastal Services Center
Coastal Change Analysis Program(C‐CAP)• NOAA maps 25% of the contiguous U.S. • Coastal Expression of the NLCD (National Land Cover Database)
NLCD is 95% C‐CAP in coastal areas
• Added focus on wetlands detail• Updated every 5 years• Produced through change detection and update mapping process
• High Resolution Available*

Wetland Potential Data Model
Office of Ocean and Coastal Resource Management | Coastal Services Center
C‐CAP Data Application:Potential Wetland ModelingBackground:• Improve wetland mapping
accuracies • Use data and methods
extendable nationally• Align with Federal Geographic
Data Committee (FGDC) wetland mapping standard
• Provide flexibility for multiple wetland definitions
• Integrate RS and ancillary data
Challenges:•Wetlands are not always wet•Canopy is not easy to see through•Landsat is often not the best scale for wetlands•Ancillary data has not been available historically•Best available data all have “warts” of their own
Office of Ocean and Coastal Resource Management | Coastal Services Center
Input Data Included:• National Wetlands Inventory (NWI)• Gridded Soil Survey Geographic (gSSURGO) Database• National Hydrography Dataset (NHD)• National Elevation Data (NED)• Landsat Imagery• Existing C‐CAP Land Cover
C‐CAP Data Application:Potential Wetland Modeling
Office of Ocean and Coastal Resource Management | Coastal Services Center
C‐CAP Data Application:Potential Wetland Modeling
• Step 1: Create a wetland potential surface from nationally available / standard data sets.– Use the strengths of each to overcome the weaknesses of others.
• Step 2: Use this layer to flag and correct the mapping of wetlands land cover categories.– Flag uplands that could be wet and wetlands that might not be.
