Dataset Information

Decadal DSMs, photomosaics and point clouds of of Apollo Bay, Victoria, Australia, created through Structure-from-Motion (SfM) technique applied to historical aerial photography taken in May 1946, Mar 1966, Jan 1971, Feb 1977 and Mar 1986. These datasets were originally generated to quantify decadal volumetric changes along sandy beaches of the iconic Great Ocean Road, in Australia. Results of this study, as well as further details of these datasets were published elsewhere (Carvalho, R. C. et al. Quantifying decadal volumetric changes along sandy beaches using improved historical aerial photographic models and contemporary data. Earth Surface Processes and Landforms, 2021).
