Topobathymetric Elevation Model of Northern Gulf of Mexico
Accurate, high-resolution elevation information is vital to understanding the highly dynamic northern Gulf of Mexico coast, the location of North America’s largest delta system and the focus of one of the largest coastal restoration and flood risk reduction efforts in the United States. The northern Gulf of Mexico topobathymetric digital elevation model (TBDEM) was developed in collaboration between
U.S. Geological Survey (USGS) Coastal and Marine Geology Program
USGS National Geospatial Program
Coastal Protection and Restoration Authority of Louisiana
and a number of federal, state, and parish agencies to create a comprehensive high-resolution, three-dimensional (3D) TBDEM for the northern Gulf of Mexico.
This TBDEM seamlessly integrates over 400 land elevation and water depth (bathymetry) datasets collected from 1888 to 2013 by
U.S. Army Corps of Engineers
National Oceanic and Atmospheric Administration (NOAA)
, and other organizations. The topographic data were obtained primarily from USGS
National Elevation Dataset
USGS Experimental Advanced Airborne Research Lidar (EAARL) data, and topographic lidar data and TBDEMs from
This 3D integrated TBDEM consists of a detailed and highly accurate elevation model incorporating the best available multi-source topographic and bathymetric elevation data for the northern Gulf of Mexico.
