Summary

The 3D Elevation Program (3DEP) is managed by the U.S. Geological Survey (USGS) National Geospatial Program to respond to growing needs for high-quality topographic data and for a wide range of other three-dimensional (3D) representations of the Nation's natural and constructed features. 3DEP informs critical decisions that are made across our Nation every day that depend on elevation data, ranging from immediate safety of life, property, and environment to long term planning for infrastructure projects. Lidar, an airborne laser detection technology for mapping features on the ground, is being collected nationwide, while Interferometric Synthetic Aperture Radar (IfSAR) is being collected over Alaska. Assessing the accuracy of the lidar [...]

Purpose

To support the USGS 3D National Topography Model (3DNTM), which includes the next generation of 3DEP and the 3D Hydrography Program, USGS is producing a Seamless 1-m DEM (S1M). As part of the accessing the accuracy of the S1M, USGS will be using consolidated vertical accuracy checkpoints that have been collected as part of 3DEP and earlier lidar mapping programs. The first version of these checkpoints was used to assess the accuracy and consistency of 3DEP in 2021. In 2024, the USGS NGTOC enriched and standardized these checkpoints to match the current survey point delivery schema so the checkpoints can be used to assess the S1M data releases.
