UAV Hyperspectral Moss Health and Lichen Classification Maps at 30 m and 70 m AGL, ASPA 135, Antarctica (Jan–Feb 2023)

This dataset contains georeferenced vegetation classification (segmentation) maps derived from drone‑mounted hyperspectral imaging (HSI) surveys acquired 28 Jan–02 Feb 2023 over ~6.5 ha of transect areas in Antarctic Specially Protected Area (ASPA) No. 135 (Windmill Islands), Antarctica. Flights were conducted at ~30 m and ~70 m above ground level (AGL), yielding ~6 cm and ~10 cm ground sampling distance (GSD) mosaics. Hyperspectral data (core) and concurrent RGB imagery (supplementary) were radiometrically calibrated, orthorectified using Global Navigation Satellite System (GNSS) Real‑Time Kinematic (RTK) ground control, and processed with machine‑learning classification workflows to map moss health condition (Healthy, Stressed, Moribund), Lichen, and Non‑vegetated surfaces.
