FY26 Status of 3DEP Quality Data

This map shows the completion of the first-ever national baseline of consistent high-resolution elevation data - both bare earth and 3D point clouds - including baseline and next generation coverage as of September 30, 2026. 3D Elevation Program (3DEP) products inform critical decisions across our Nation that depend on 3D data, from immediate safety of life, property, and environment to long-term planning for infrastructure projects. Explore and access 3DEP data at USGS LidarExplorer or The National Map.

Explanation

• 3DEP Baseline Data¹
  • Dark Green = Available or In-Progress
  • Dark Blue = IfSAR Available (Alaska)
  • Light Green = Digital Surface Model (DSM) Planned

While every effort is made to ensure accuracy, errors or omissions may be present.

¹Some areas may be restricted

• 3DEP Baseline:
  • Quality level 2 or better lidar data (IfSAR in AK)² 

²3D Point Clouds and Bare Earth DEMs as defined in 3DEP Lidar Base Specification v1.2 or later and the 1-Meter Digital Elevation Model Specification, TM-11B7
