Overview
USGS Coastal and Marine Geology Program investigates the extent and causes of coastal impacts of hurricanes and extreme storms on the coasts of the United States. Our overall objective is to improve the capability to predict coastal change that results from severe tropical and extra-tropical storms. Such a capability will facilitate locating buildings and infrastructure away from coastal change hazards.
Extreme storm investigations have three integrated components:
Scanning Airborne Laser Altimetry (Lidar):
With our partners in NASA and NOAA, USGS acquires laser altimetry surveys that are providing unprecedented data to investigate the magnitude and causes of coastal change.
Oblique Aerial Video & Photography:
USGS acquires GPS-controlled pre- and post-storm oblique imagery to document coastal changes and to assist in interpreting the laser altimetry data.
Ground Surveys:
USGS deploys ground crews to document coastal changes in detail and to acquire high resolution GPS ground surveys to verify the laser altimetry data.
