Dates

Published: July 8, 2025

Last Revised: March 13, 2026 (ver. 2.0)

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.

Digital Elevation Model (DEM) Data

  • Topobathymetric digital elevation model of Elim, Alaska, 2015 to 2019

    This dataset contains a 1-meter resolution, seamless topobathymetric digital elevation model (TBDEM) and associated spatial metadata for Elim, Alaska. The TBDEM contains best available multi-source topographic and bathymetric elevation data collected between the years 2015 and 2019. Processing was done by the U.S. Geological Survey (USGS), Pacific Coastal and Marine Science Center (PCMSC) and results are provided as a Cloud Optimized GeoTIFF (COG).
