    High-resolution lidar data for infrastructure corridors, Big Delta Quadrangle, Alaska

    Metadata Updated: July 5, 2023

    In advance of design, permitting, and construction of a pipeline to deliver North Slope natural gas to out-of-state customers and Alaska communities, the Division of Geological & Geophysical Surveys (DGGS) has acquired lidar (light detection and ranging) data along proposed pipeline routes, nearby areas of infrastructure, and regions where significant geologic hazards have been identified. Lidar data will serve multiple purposes, but have primarily been collected to (1) evaluate active faulting, slope instability, thaw settlement, erosion, and other engineering constraints along proposed pipeline routes, and (2) provide a base layer for the state-federal GIS database that will be used to evaluate permit applications and construction plans. The vegetation digital surface models (veg_DSM) represent the above ground elevation of the highest laser return with all vegetation greater than 20 cm above the ground included.
