3DNTM Timeline

The 3D National Topography Model (3DNTM) is a vision for an integrated 3D model of elevation and hydrography data that will support a broad range of  applications as shown in table 1 below. 3DNTM includes the completion of the 3D Elevation Program baseline, the development of the 3D Hydrography Program, the implementation of the next generation of 3DEP, and a vision for a future 3D model to fully integrate 3DEP, 3DHP and other data from The National Map.  The components of 3DNTM are in various stages of implementation and timelines are contingent on funding.
