CoastSnap is a global citizen science project to capture our changing coastlines. No matter where you are in the world, if you have a smartphone and an interest in the coast, we welcome you to participate! 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.
Using a specialised technique known as photogrammetry, CoastSnap turns your photos into valuable coastal data that is used by coastal scientists to understand and forecast how coastlines might change in the coming decades. Photogrammetry enables the position of the coastline to be pinpointed from your snaps to an accuracy similar to that of professional coastal survey teams. All we ask is that you take the photos at the same location (by using one of our official CoastSnap camera cradles or a do-it-yourself adaptation) and record the precise photo time in the App. The more photos we have of a particular site, the better our understanding becomes of how that coastline is changing over time.
Coastal areas are in constant evolution, climate change will impact where and how humans live. In times of the imminent climate crisis, the coastline will change dramatically, and extreme weather phenomena are already starting to be part of our daily life.
The Coastal Observer Citizen Science project explores these effects and their impact on the environment and our mood. The Coastal Observer App encourages citizens to become active in monitoring weather and water locally, and will help researchers build a pathway for a sustainable future. By contributing observations about floods, tides storms and water quality, you can help the University of Delaware, US, with their research.
