CoastSnap relies on repeat photos at the same location to track how the coast is changing over time due to processes such as storms, rising sea levels, human activities and other factors. Monitoring groups can install a camera bracket and sign to encourage passers-by to take and submit photos of the same scene over time. Different CoastSnap stations employ different methods for submitting photos, including the optional use of the CoastSnap app. Over time, the photos can be made into timelapse videos showing shoreline change and improving understanding of how change occurs over time.
