The data contains two high-resolution, UAV derived orthomosaics and digital elevation models of the drained ice-dammed lake basin topography and ice margin at Russell Glacier, West Greenland surveyed on the 3rd and 6th September 2021. The UAV flights were conducted on two different dates using two different UAVs, due to the battery capacity and weather conditions. The ice margin (Mission I) was surveyed on the 3/9-2021 using a Fixed-wing, WingtraOne w. multi-frequency L1/L2 GNSS receiver. The drained lake basin topography (Mission II) was surveyed on the 6/9-2021 using a Quadcopter, DJI Phantom 4 Pro w. a KlauPPK 7700C GNSS receiver. The UAV images were processed using a structure-from-motion (SfM) workflow in Agisoft Metashape Pro. (v. 1.7.4). DEMs and orthomosaics for Mission I have a resolutions of 0.1 and 0.04 m, respectively, while for Mission II both have a resolution of 0.1 m The estimated uncertainty of the DEMs are X = -0.43 m, Y = 0.11 m and Z = 0.53 m.
