    Alaska Division of Geological & Geophysical Surveys (Point of Contact)
    Area covered
    Barry Arm, Alaska, Southcentral Alaska
    Description

    Lidar-derived elevation data for Barry Arm, Southcentral Alaska, collected September 19, 2023, Raw Data File 2025-8, releases classified point cloud, digital terrain model (DTM), and an intensity model of Barry Arm, Southcentral Alaska, during leaf-on conditions. The survey provides snow-free surface elevations for use in landslide change detection. Aerial lidar data were collected on September 19, 2023, and ground control data were collected on August 2, 2021, and May 5, 2023, and subsequently merged and 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/10.14509/31520).
