Abstract

The Alaska Department of Natural Resources, Division of Geological and Geophysical Surveys (DGGS) conducts lidar surveys in accordance with our mission to study potential geologic hazards to infrastructure. We use our in-house lidar system to perform medium-scale, often repeat surveys of landslide hazard areas, avalanche hazard areas, permafrost evolution areas, and areas of incompletely surveyed tectonic fault systems. Oftentimes we partner with other agencies or universities. Our data published prior to 2022 can be found at the DGGS Elevation Portal, and publications since 2022 are available on our publications page.
