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.
3DEP is truly a community effort, the partners that fund acquisition, the vibrant lidar industry and private sector mapping firms that collect data, and an innovative user base.
The 3D Elevation Program 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.
3DEP is based on the results of the National Enhanced Elevation Assessment (NEEA) that was funded by National Digital Elevation Program (NDEP) agencies and completed in 2011. The study, led by the USGS, identified more than 600 requirements for enhanced (3D) elevation data to address mission-critical information requirements of 34 Federal agencies, all 50 States, and a sample of private sector companies and Tribal and local governments.
The first full year of 3DEP production began in 2016 and at the end of fiscal year 2022, 89.5% of the Nation has available or in progress elevation data that meet 3DEP specifications for high accuracy and resolution. We must also continue to look forward to the challenges of completing nationwide coverage and meeting growing needs for higher quality data, repeat coverage, and new products and services.
