From U.S. Geological Survey (USGS):
3DEP and America's Infrastructure: The USGS is seeing a dramatic increase in the use of 3 dimensional geospatial data for infrastructure planning, modeling and construction. Infrastructure and construction management, which encompasses the physical framework of transportation, energy, communications, water supply, and other systems, are critical to the Nation’s prosperity. Industries, governments and other public and private agencies are progressively using 3D light detection and ranging (lidar) elevation data, as part of the national 3D Elevation Program, to improve productivity, safety, and cost-savings for infrastructure projects.https://on.doi.gov/2uJ6EQg
