The US Interagency Elevation Inventory, or USIEI, is a nationwide listing of known publicly available high-accuracy topographic and bathymetric source elevation data for the United States and its territories. The inventory provides a single resource for information about all known completed and in-progress broad-area public domain elevation data.
Collaborate with Others
The USGS National Geospatial Program (NGP) manages the 3D Elevation Program (3DEP), a program designed to acquire nationwide lidar for the lower 48, Hawaii and the US Territories, and IfSAR data over Alaska. The NGP works with Federal, State, Tribal, and local agencies to set priorities and establish the annual acquisition plans.

Sharing Proposed 3DEP Areas of Interest
The USGS anticipates funding another round of projects in FY22. The Federal agencies that partner on the 3DEP have compiled their priorities for lidar acquisition and published them on an interactive online map. Overlap with these Federal priorities will be one of the key evaluation criteria. Interested parties are encouraged to share their potential projects through this system in order to assist in finding additional partners for projects.
About SeaSketch: View Proposed Collection Areas
The 3D Elevation Program and the Interagency Working Group on Ocean and Coastal Mapping have established a system to share information about areas of interest, proposed and planned elevation projects. Planned and potential Federal projects as well as State and local areas of interest are available at the NOAA sponsored SeaSketch site: U.S. Federal Mapping Coordination, A Collaboration Site for Federal and Partner Mapping Data Acquisition.
All Federal agency and stakeholder areas of interest will be made available for viewing through this site to enable comparison and facilitate discussion with other 3DEP stakeholders. This mapping site is comprehensive, showing areas of interest, proposed, planned, in-work, and completed elevation and related projects.

Viewing Instructions and basic tutorials on how to use the SeaSketch system are available on the SeaSketch Knowledgebase website. Alternatively, video lesson 11d below, shows you how to zoom to your area of interest and view the footprints of existing and proposed topographic lidar projects.
