Which program aims to provide digital elevation data for the entire United States?

The 3D Elevation Program (3DEP) is specifically designed to collect and deliver high-quality, high-resolution elevation data across the entire United States. This program emphasizes the importance of providing consistent, accurate, and up-to-date elevation models that can serve various applications such as flood modeling, infrastructure development, and natural resource management.

The 3DEP aims to produce seamless elevation data that can be used in conjunction with different geographic information systems (GIS) and other spatial data analytics. By utilizing advanced technologies like LiDAR (Light Detection and Ranging), 3DEP ensures that the elevation data it produces is comprehensive and detailed, capturing the subtle variations in terrain necessary for effective analysis.

While the National Elevation Dataset provides elevation data, it does not encompass the increased scope and ongoing ambitious goals of the 3D Elevation Program. The Global Elevation Model generally refers to global datasets, rather than specifically focusing on U.S. data. Although the U.S. Geological Survey (USGS) plays a role in many elevation-related initiatives, the structure and comprehensive coverage of the 3D Elevation Program highlight its primary aim and focus on national elevation data collection.
