Data
Coastal Change Analysis Program Regional Land Cover
Produced and distributed by the NOAA Coastal Services Center
The Coastal Change Analysis Program (C-CAP) is nationally standardized land cover and land change information for the coastal regions of the U.S. C-CAP products feature 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 has completed two time periods (1996 and 2001) for most areas of the country and is currently working to complete a 2005 – 2006 update to these data by 2010.
