Weekly update

The United States Geological Survey (USGS) partnered with NASA to create a map showing critical elevations of the South Atlantic coast that indicate coast vulnerabilities to storm surge overtopping, hurricanes and extreme storms. The map details were gathered by NASA’s Airborne Topographic Mapper (ATM), an airplane mounted NASA laser.

The partnership has also developed a new scale to categorize expected coastal changes that occur during storms. The map and scale were announced at the National Hurricane Conference in Washington, D.C., held in April 2001.

Both the scale and map can be accessed online at http://coastal.er.usgs.gov/hurricanes/mappingchange/.
