Overview

View the current status of this data set

The Coastal Change Analysis Program (C-CAP) produces a nationally standardized database of land cover and land change information for the coastal regions of the U.S. C-CAP products provide inventories of coastal intertidal areas, wetlands, and adjacent uplands with the goal of monitoring these habitats by updating the land cover maps every five years. C-CAP products are developed using multiple dates of remotely sensed imagery and consist of raster-based land cover maps for each date of analysis, as well as a file that highlights what changes have occurred between these dates and where the changes were located.

NOAA also produces high resolution C-CAP land cover products, for select geographies.  These products focus on bringing NOAA’s national mapping framework to the local level, by providing complimentary data, at a more detailed resolution to compliment regional C-CAP land cover.
