Abstract
The USGS 3D National Topography Model (3DNTM) is a new initiative that updates, improves, and integrates USGS elevation and hydrography data. High-resolution lidar elevation data have been collected across much of the conterminous US through the 3D Elevation Program (3DEP). 3DEP data will be used as the source to derive a positionally accurate and detailed stream network, called the 3D Hydrography Program (3DHP). The implementation of 3DHP marks the start of a new era of water data.
