Abstract:
The data were derived from uncrewed aerial vehicle (UAV, DJI Phantom Pro P4 Multispectral for 2022-2024, and DJI Phantom Pro RGB for 2025, all with DJI RTK base station for positioning) images. Our data were acquired at a thermo-erosional gully site (BAP-B) on the Baldwin Peninsula in Northwestern Alaska. The BAP-B site is a coastal gully exceeding 10 m incision into the surrounding hillslope terrain. Data acquisition took place during expeditions in the area during different months (15.08.2022, 13.09.2023, 25.06.2024, 20./25.07.2025). For the UAV data derived DSMs and orthomosaics from the densely overlapping visible-spectrum imagery acquired during drone flights over multiple years using photogrammetric software (Agisoft metashape) for structure-from-motion (SfM) image processing, and finely co-registered them using arosics and xdem. The data provided here was part of a several year revisit campaign to monitor rapid permafrost degradation and related thaw processes. In addition, we used early-summer imagery from 2024 to derive the heights of snow remnants in the thermo-erosional gully.
