Alaska Statewide Interferometric Synthetic Aperture Radar (InSAR) Elevation Data and Satellite Imagery Status
The USGS 3D Elevation Program (3DEP) effort to acquire new statewide Alaska elevation data is complete. The overall goal of 3DEP is to complete acquisition of the first-ever national baseline of consistent high-resolution elevation data—both bare-earth and three-dimensional point clouds—collected in a timeframe of less than a decade.
