  • The 2022 3D Nation Elevation Requirements and Benefits Study conducted by NOAA and USGS is being used to plan for the next generation of 3DEP after nationwide coverage has been completed. The 3D Nation study also looked at the requirements and benefits of bathymetry for the inland, nearshore, and offshore zones. 

  • The 3DEP baseline program is based on the results of the 2012 NEEA study that identified more than 600 requirements for 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.
