What is CoastSnap and how does it work?

CoastSnap is a global Citizen Science project aimed at mapping our changing coastlines. To achieve this, we need your help. CoastSnap works based of a series of images shot the same location, taken from one of our official CoastSnap camera holders. The more pictures we gather of a particular beach, the better we are able to understand how that coastline changes over time.

Step 1

By scanning the QR code on the CoastSnap camera mount our web application will be opened with further instructions. When a photo has been taken with the smartphone, it is shared anonymously with our server for further processing.

Step 2

Using a smart algorithm, CoastSnap is able to determine the position of the waterline in your photo. This algorithm is able to achieve an accuracy comparable to that of professional coastal research teams. By collecting a series of the development of the waterline position we can build a valuable database. Thanks to this data, coastal researchers can understand and predict how coastlines may change in the coming decades, as a result of storms, the seasons, sea level rise and human activities.

Step 3

In the web application you are showed the photo you shared with the position of the waterline indicated, as determined by the algorithm. This edited image can then be shared via various social media channels.

What is the purpose of CoastSnap?

CoastSnap is an affordable tool that provides researchers and policymakers insight in the daily development of the Dutch coast. By involving citizens (tourists and locals) in the data collection process, CoastSnap provides information about the processes that affect our beaches to those interested.
