The Alaska Division of Geological & Geophysical Surveys (DGGS) used aerial lidar to produce a classified point cloud, digital terrain model (DTM), surface model (DSM), and intensity model of land areas in northern Barry Arm, northwest Prince William Sound, Alaska, during near snow-free ground conditions on June 26, 2020. The goal of the survey is to provide high quality, modern topographic data in the recently deglacierized part of Barry Arm where significant landslide hazards exist. Aerial lidar and ground control data were collected on June 26, 2020, and subsequently processed in Terrasolid and ArcGIS. Ground control was collected on June 26, 2020, as well. All files can be downloaded free of charge from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/30589).

Lidar-derived elevation data for lower Serpentine Glacier and adjacent slopes, Southcentral, Alaska, collected October 14, 2022, Raw Data File 2023-14, uses aerial lidar to produce a classified point cloud, a digital terrain model (DTM), and an intensity model of the unstable slope at Serpentine Glacier, located in Prince William Sound in Southcentral Alaska. Aerial and ground control data were collected on October 14, 2022, and subsequently processed using a suite of geospatial processing software. These data support a paraglacial rock slope destabilization study at Serpentine Glacier and will be used to assess and characterize an ongoing landslide hazard.

The Alaska Division of Geological & Geophysical Surveys (DGGS) used lidar to produce digital terrain models (DTM), a digital surface model (DSM), and an intensity model for evaluations of the Grewingk Glacier 1967 landslide scar located above the proglacial lake on the north-facing flank of the glacial valley in Kachemak Bay State Park, Alaska. DGGS capitalized on a data collect (Salisbury and others, 2021) conducted in Homer the same day for a landslide hazard resiliency project. Lidar and Global Navigation Satellite System (GNSS) data were collected on June 3, 2019, and subsequently processed using TerraSolid and ArcGIS. The Alaska Division of Mining, Land, & Water (DMLW) Survey Section conducted a targeted Ground Control Survey for the Homer project on June 19-20, 2019, and we use these ground control data for the Grewingk Glacier dataset across Kachemak Bay. These data are being released as a Raw Data File with an open end-user license. All files can be downloaded free of charge from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/30599).
