TESTCLONE Super-high-resolution aerial imagery, digital surface model and 3D point cloud of Herschel Island, Canada

DOI

As part of the MOSES airborne campaign led by the Alfred Wegener Institute in 2018, we collected super-high-resolution multispectral imagery of permafrost landscapes with the Modular Aerial Camera System (MACS), developed by the German Aerospace Center. From these images, we photogrammetrically processed four-band orthophotos (blue, green, red, near-infrared) and digital surface models at a spatial resolution of 7 cm, as well as photogrammetric point clouds in RGB and NIR at 48.03 px/m³ and 17.85 px/m³ respectively. This dataset covers approximately 1.38 km² of Herschel Island on the Yukon Coast, Canada, with all images collected on 15 August 2018. This super-high-resolution dataset provides opportunities for generating detailed training datasets of permafrost landform inventories, a baseline for change detection for thermokarst and thermo-erosion processes, and upscaling of field measurements to lower-resolution satellite observations.
