Description
Lidar-derived elevation data for Cordova, Southcentral Alaska, collected August 18-19, 2023, and September 19 and 22, 2023, Raw Data File 2024-6, classified point cloud, digital surface model (DSM), digital terrain model (DTM), and an intensity model of Cordova, Southcentral Alaska during leaf-on conditions. The survey provides snow-free surface elevations for landslide and avalanche hazard assessments. Ground control data were collected August 16-17, 2023; aerial lidar data were collected August 18-19, 2023, and September 19 and 22, 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/10.14509/31159).
