Sommario:
- As part of the ThawTrend-Air airborne campaign led by the Alfred Wegener Institute in 2019, 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 very high spatial resolution of 7 cm, as well as photogrammetric point clouds in RGB and NIR. This data collection aggregates nine data subsets of the Ketik fire scar, Alaska, covering approximately 75 km². All images were collected on 27 July 2019.
