Summary
This data release consists of a series of seamless topobathymetric digital elevation models (TBDEMs) for coastal Alaskan communities. Each TBDEM was assembled from best available, multi-source topographic and bathymetric elevation data collected at the time of processing. These products were created to support the development of dynamic flood models, but are also intended for reuse by scientists, managers, and the general public.
