ASC Data Repository
This dataset consists of the complete set of aerial imagery and data from walrus haulouts collected by unoccupied aerial system (UAS) surveys near Pt. Lay, Alaska, during the autumns of 2018 and 2019. The data include: 1) georeferenced digital aerial imagery and flight logs from UAS surveys, and 2) orthoimages derived from the aerial imagery and flight logs by standardized structure from motion algorithms.
Because these high resolution images are considered sensitive, they are archived at the U.S. Geological Survey, Alaska Science Center (a USGS Trusted Digital Repository) and only the metadata describing the data set is publicly accessible. However, data derived from these images are available through a related data release: Fischbach et al. (2021).
