The 3D National Topography Model Call for Action— Part 2: The Next Generation 3D Elevation Program report outlines how USGS is aligning and integrating 3D elevation and hydrography data under the umbrella of the 3D National Topography Model. The report explains how the USGS used the results of the 3D Nation Study to develop a new program design, and includes all the details about the next generation of 3DEP. 

What’s new for the next generation of 3DEP? 

• Enhanced lidar quality levels and refresh rates, giving users better, faster data 

• Greater program flexibility to meet changing needs and take advantage of advancements in mapping technologies 

• A stronger focus on interagency collaboration, for both land topography and bathymetry of inland rivers 

• A research-forward approach that fosters innovation, agility, and adaptability 

• Transforming how products and services are delivered to make data easily accessible and analysis-ready
