North Carolina Sea Grant, using Google satellite imaging, looked at coastal erosion dating back to 1984.
Spencer Rogers is the N.C. Sea Grant coastal construction and erosion specialist. He said tracking the changes over time is important not only for public policy, but for property owners as well.
“One of our goals in Sea Grant is to make sure people understand the rapid changes that are taking place at these inlets,” he said. “Understanding what those changes are, and what the consequences are over time, is important if you are living on the beach communities, or buying and selling property.”
The maps were built using the Google Earth Timelapse feature, which allows users to zoom in or out on areas around the country and world.
