Lidar-derived elevation data for Napakiak, Southwest Alaska, collected August 20, 2022

Description

Lidar-derived elevation data for Napakiak, Southwest Alaska, collected August 20, 2022, Raw Data File 2024-12, provides aerial lidar-derived classified point cloud data, a digital surface model (DSM), a digital terrain model (DTM), and an intensity model of Napakiak, Southwest Alaska, during leaf-on conditions. The survey provides snow-free surface elevations for flooding hazard assessment and coastal erosion studies. Ground control data were collected October 8, 2020, and aerial lidar data were collected August 20, 2021, 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/10.14509/31258).
