Lidar-derived elevation data for Portage, southcentral Alaska, collected October 15, 2020
Description
Lidar-derived elevation data for Portage, southcentral Alaska, collected October 15, 2020, Raw Data File 2024-7, provides aerial lidar-derived classified point cloud data, a digital surface model (DSM), a digital terrain model (DTM), and an intensity model of slopes above Portage Glacier, Southcentral Alaska, during leaf-off conditions. The survey provides snow-free surface elevations for use in landslide and avalanche hazard assessments. Aerial lidar data were collected on October 15, 2020, and ground control data were collected on November 13, 2020, 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.
