Abstract:
The data were derived from airborne images from the modular aerial camera system (MACS, developed by the German Aerospace Center, Lehmann et al. 2011). Our data were acquired at a thermo-erosional gully site (CSP-F) on the central Seward Peninsula in Northwestern Alaska. The gully CSP-F is connected to a thermokarst pond basin, which drained around 20 years ago. The MACS data is from 01.07.2024 (Grosse et al. 2025, Rettelbach et al. 2024). The DSM and orthomosaic were derived from the densely overlapping visible-spectrum imagery from airborne MACS using photogrammetric software (pix4D) for structure-from-motion (SfM) image processing. They were then finely co-registered using AROSICS (Scheffler et al. 2017) and xDEM (xDEM contributors 2024). The data provided here was part of a several year revisit campaign to monitor rapid permafrost degradation and related thaw processes.
