DEMs and orthophotos generated from 7 UAV survey flights conducted in February 2022

DOI

In February 2022, seven UAV photogrammetry flights were conducted near the Qinling Station, located on Inexpressible Island, Victoria Land, East Antarctica, specifically on February 1st, 2nd, 6th, 7th, 10th, 16th, and 19th. A total of 3,245 images were captured at a flight altitude of 23 meters, yielding a ground sampling distance (GSD) of 0.5 cm. The UAV employed oblique photogrammetry with a camera tilt angle of 45 degrees. The collected imagery underwent combined alignment and dense point cloud reconstruction, resulting in the generation of digital elevation models (DEMs) and orthophotos. The dataset includes both snow sastrugi and exposed rock surfaces, providing high-resolution inputs that support detailed remote sensing investigations of the region.
