CoastSnap was founded in 2017 as a pilot project between the UNSW Water Research Laboratory and the NSW Department of Planning, Industry and Environment. The pilot project conststed of two CoastSnap stations installed on the Northern Beaches of Sydney (Australia). The very first station was installed at Manly Beach on the 17 May, 2017 and the second station at North Narrabeen on the 23 May, 2017. The aim of the pilot project was to develop algorithms to map shoreline change from community images.


The results of this were written up in the Coastal Engineering  journal:
