Imagery and digital surface model for the Slumgullion landslide, Lake City, Colorado, June 3, 2024

This dataset contains a point cloud (Slumgullion_PointCloud.laz), 1-meter digital surface model (Slumgullion_DSM.tif), and orthoimagery (0.1-meter resolution) (Slumgullion_Ortho.tif) of the active portion of the Slumgullion landslide in Lake City, Colorado. The Slumgullion landslide is a translational slide with a continuously moving, active portion and an inactive portion. 896 photos from a Sony A7R Mark IV, RGB61 camera mounted on a Wingtra 1 GEN II fixed-wing uncrewed aerial vehicle (UAV) were collected on June 3, 2024 (Slumgullion_UAV_Images_Geotags.zip). The images were georeferenced using post-possessed kinematics (PPK) from the onboard Global Positioning System (GPS) of the aircraft with corrections from a concurrently operating base station within the study area. The point cloud and digital surface model products were created from the georeferenced photos from four UAV flights using Structure-from-Motion (SfM) photogrammetry techniques with the software Agisoft Metashape (v. 2.1.0 build 17532).
