Lidar-derived elevation data for Columbia Glacier terminus and adjacent slope, Southcentral Alaska, collected September 18, 2022

Description

Lidar-derived elevation data for Columbia Glacier terminus and adjacent slope, Southcentral Alaska, collected September 18, 2022, Raw Data File 2023-16, provides an aerial lidar derived classified point cloud, a digital terrain model (DTM), and an intensity model of the unstable slope at the terminus of Columbia Glacier, located in Prince William Sound in Southcentral Alaska. Aerial and ground control data were collected on September 18, 2022, and subsequently processed in a suite of geospatial processing software. These data support a paraglacial rock slope destabilization study at Columbia Glacier and will be used to assess and characterize an ongoing landslide hazard. All files can be downloaded from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/31032).
