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. The timeframe for this metadata is 2020 through 2023, depending on the latest date of available imagery. These maps were developed for NOAA by Ecopia (ecopiatech.com) utilizing high resolution 30cm or better aerial imagery. In addition, a digital surface model (DSM) derived from the stereo imagery was used to determine vegetation heights. This information provides managers with a detailed accounting of current landscape conditions related to impervious surface, woody canopy, and water feature extents.
