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.
