A team of researchers from TU Delft has succeeded in long-term mapping of beach topography to within a few centimeters. The unique dataset provides insights into coastal changes for every hour, for three years. This data is important for dune maintenance and to keep the hinterland well protected. The methodology is also being used to monitor other coastlines and even glaciers. The data are open source and were published in Scientific Data in 2022. The new methodology was also recently published.
