These points provide the calculated XYZ (horizontal and vertical) coordinates and RGB (red-green-blue) values of the land surface on the north coast of Barter Island Alaska collected on three dates over one calendar year. The data were acquired in order to demonstrate the utility of using structure-from-motion photogrammetric methods for deriving digital elevation data using imagery acquired from a fixed-wing aircraft in remote environments. Companion data sets, including orthophotomosaics and digital surface models are used to evaluate fine-scale morphological and volumetric change to beaches and permafrost bluffs.
