Lidar-derived elevation data for Blackerby parcel, Juneau, southeast Alaska, collected July 12, 2023
Lidar-derived elevation data for Blackerby parcel, Juneau, southeast Alaska, collected July 12, 2023, Raw Data File 2024-8 releases classified point cloud derived from aerial lidar, along with a digital surface model (DSM), a digital terrain model (DTM), and an intensity model of slopes above the Blackerby Parcel in Juneau, Southeast Alaska, during leaf-on conditions. The survey provides snow-free surface elevations for use in landslide hazard assessment, geologic mapping, and slope-stability analysis. Ground control data provided by the Alaska Department of Transportation (DOT) was collected on March 21, 2017. DGGS collected aerial lidar data on July 12, 2023, and subsequently merged and processed using a suite of geospatial processing software. This collection is available as a Raw Data File under an open end-user license.
