United States Interagency Elevation Inventory

View a nationwide listing of known high-accuracy topographic and bathymetric data, with descriptive data and direct links or contact information to access each dataset.

The project is a collaborative effort of the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Geological Survey, with contributions from the Federal Emergency Management Agency. This resource is a comprehensive, nationwide listing of known high-accuracy topographic data, including lidar and IfSAR, and bathymetric data, including NOAA hydrographic surveys, multibeam data, and bathymetric lidar. The topographic information was updated June 2014, with future updates occurring annually. Bathymetric information is current as of November 2012. The inventory is also available as a web service from NOAA's Office of Coastal Management.

The information provided for each elevation dataset includes many attributes such as vertical accuracy, point spacing, and date of collection. Also provided are a point of contact for the data and a direct link to access the data, if available.
