Bare-earth digital terrain model of road damaged by landslide
Detailed Description
In 2024, the U.S. Geological Survey (USGS) National Uncrewed Systems Office (NUSO) provided technical support for the National Park Service in assessing road damage and landslide hazards along the Blue Ridge Parkway following Hurricane Helene. USGS NUSO remote pilots collected small uncrewed aircraft system (sUAS)-based lidar data at strategic locations along the parkway in North Carolina. This bare-earth digital terrain model was created from the sUAS lidar point cloud after removing vegetation. By eliminating vegetation-classified points, the extent of landslide damage to the road becomes much more apparent
