CoastSnap is a citizen science project that uses repeat photography to monitor changes in coastlines. The photos are processed using photogrammetry to create valuable data for scientists studying coastal dynamics.
The photogrammetry technique used by CoastSnap allows for pinpointing the coastline's position with accuracy comparable to professional coastal survey teams.
To participate, you need a smartphone and an interest in the coast. It's recommended to use an official CoastSnap camera cradle or a DIY adaptation and record the precise photo time in the app.
CoastSnap is developed by SPOTTERON GmbH and runs on the SPOTTERON Citizen Science platform.
CoastSnap is available for iPhone, iPad, and iPod devices.
