US Interagency Elevation Inventory
Information and Instructions
The U.S. Interagency Elevation Inventory shows availability of high-accuracy topographic and bathymetric data for the United States and its territories. The project is a collaborative effort between NOAA and the U.S. Geological Survey, with contributions from the Federal Emergency Management Agency, U.S. Department of Agriculture, and U.S. Army Corps of Engineers. 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 last comprehensive update to the topographic portion of the inventory was completed in March 2015. However, many corrections and additions are made between comprehensive updates. Bathymetric data are current as of November 2012. These data are static snapshots of availability that will soon be replaced with a dynamic map service.
The information provided for each elevation dataset includes many attributes such as vertical accuracy, point spacing, and date of collection. A direct link to access the data or information about the contact organization is also available through the inventory.
If you know of additional datasets that could be included in the inventory, please contact the NOAA Office for Coastal Management.

To use the United States Interagency Elevation Inventory through OpenTopography simply check the desired layers (top right corner) and explore the availability by browsing the map. The areas of available data will be outlined and clicking on the area will reveal the available metadata and how to access the data on an agency website (e.g., NOAA, NPS). Links in the pop-up will take you to an external webpage.
