Description
Lidar-derived elevation data for Goodwin Glacier, Southcentral Alaska, collected September 22, 2023, Raw Data File 2025-7, releases classified point cloud, digital terrain model (DTM), and an intensity model of Goodwin Glacier, Southcentral Alaska, during minimum snow cover conditions. The survey provides snow-free surface elevations for use in change detection following the landslide that occurred on August 10, 2023, covering a large portion of Goodwin Glacier. Aerial lidar data were collected September 22, 2023, and subsequently processed using a suite of geospatial processing software. This data collection is released as a Raw Data File with an open end-user license. All files can be downloaded from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/31519).
