A data-driven determination of the coastline

  • Jesper Sejberg Christiansen LE34


Our coast is constantly changing. And if the coast is your neighbor, there is a risk that your property will shrink or expand year by year. The boundaries of the land register are not always updated, and the coastal boundaries can only be moved at the owner's initiative and primarily on the basis of expensive, manual surveying.

Today, we have access to huge amounts of open and free data in high quality. Can we take advantage of this, and is there an easier and cheaper alternative that is based on data rather than estimates, and which can be implemented much more easily for the digitization of the entire country's coast compared to the traditional manual methods?
