Bathymetric Dynamic Digital Elevation Model for the Northern Gulf of Mexico.

The Bathymetric Dynamic Digital Elevation Model (BDDEM) was developed using open source software. The BDDEM's initial basis was obtained by merging the five digital elevation models of the Northern Gulf region released by the National Centers for Environmental Information. The final build of the BDDEM includes all of the National Ocean Service hydrographic surveys conducted in Alabama, Mississippi and Louisiana through 2011. The digital elevation model (BDDEM) is available at resolutions of 3, 1 and 1/3 arc seconds.
