Using a terrestrial laser scanner, these data have been measured just after the storm of january 2012. It includes a part of the Petten Sea Defense and the adjacent dune area. During the storm an erosion length of about 7m was observed at the transition between dune and dike. The data is obtained from Petra Goessen from Hoogheemraadschap Hollands Noorder Kwartier (HHNK). The data has been collected by RWS.
