3D Elevation Program

Home

To respond to growing needs for high-quality elevation data, the goal of 3DEP is to complete acquisition of nationwide lidar (IfSAR in AK) by 2023 to provide the first-ever national baseline of consistent high-resolution topographic elevation data – both bare earth and 3D point clouds – collected in a timeframe of less than a decade.
