Description
Lidar-derived elevation data for Tuntutuliak, Southwest Alaska, collected August 18, 2021, Raw Data File 2023-17, provides aerial lidar derived classified point cloud data, a digital surface model (DSM), a digital terrain model (DTM), and an intensity model of Tuntutuliak, Southwest Alaska. Data were collected during leaf-on ground conditions. The survey provides snow-free surface elevation data for assessing coastal erosion and flooding hazards. Ground control data and aerial lidar data were collected on August 18, 2021, and subsequently processed using a suite of geospatial processing software. All files can be downloaded from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/31033).
