Unmanned aerial vehicle (UAV) imagery of the surface of the Greenland Ice Sheet ablation area collected with a 3DR Solo quadcopter mounted with a Canon S110 digital camera (12 megabytes (MB)). Four flights were flown within 1 hour of solar noon to collect a total of 1,196 RGB images in RAW format. Flights were run with flight planner to ensure 80% overlap and four ground control point plastic trays were surveyed using a Trimble R7 Global Navigation Satellite System (GNSS) during the flights to conduct the georeferencing. The images were mosaiced using Agisoft Metashape Pro version 1.6.5. The camera adjustment parameters can be found in the supplementary table of "Terrain-Based Shadow Correction Method for Assessing Supraglacial Features on the Greenland Ice Sheet" by Sasha Leidman, Asa Rennermalm, Matthew Cooper, and Richard Lathrop. The imagery and Digital Elevation Model (DEM) were used as a sample dataset for a novel shadow correction method described in the manuscript. The imagery shows a 1.3 square kilometers (km2) area characterized by rough topography, bare ice, and supraglacial river networks.
