Mobile Bay is ecologically important as it is the fourth largest estuary in the United States. The Mobile Bay topobathymetric digital elevation model (TBDEM) was developed in collaboration between U.S. Geological Survey (USGS) Coastal and Marine Geology Program (CMGP) and USGS National Geospatial Program (NGP) using a combination of 71 disparate topographic and bathymetric datasets collected from 1917 to 2011 by USGS, National Oceanic and Atmospheric Administration and other organizations. The topographic data were obtained primarily from USGS National Elevation Dataset at 1/9-arc-second resolution (~3 m), USGS Experimental Advanced Airborne Research Lidar (EAARL) data (2 m), and topographic lidar data (2 m) and Compact Hydrographic Airborne Rapid Total Survey (CHARTS) lidar data (2 m) from U.S. Army Corps of Engineers.

Coastal National Elevation Database (CoNED) Applications Project
High-resolution coastal elevation data is required to identify flood, hurricane, and sea-level rise inundation hazard zones and other earth science applications, such as the development of sediment transport and storm surge models. Light detection and ranging (lidar) enables the rapid collection of very accurate elevation data over large areas, and during the last decade, airborne laser altimetry...Coastal National Elevation Database (CoNED) Applications Project
