About John McCombs
I have been with the Coastal Remote Sensing Program at the NOAA Coastal Services Center in Charleston, South Carolina, since 2003. At the Center, I oversee the quality control of the Center’s moderate-resolution Coastal Change Analysis Program (C-CAP), as well as coordinate mapping efforts in support of the Sea Level Rise and Coastal Flooding Impacts Viewer. Before NOAA, I worked on Gap Analysis Program land cover mapping projects in Virginia and Mississippi and helped run the Spatial Information Technologies Laboratory at Mississippi State University.
