In 2014 started the survey project for Bagger- en Aannemingsmaatschappij Van der Kamp. This project was commissioned by Rijkswaterstaat and the Port of Rotterdam. The activities are monthly monitoring the bottom position of the Nieuwe Waterweg in Rotterdam, The Netherlands, by use of multibeam. All measurements are performed by the Profiler and Nikyra. The survey data is being processed into rapports at our office. This data is used by Van der Kamp to maintain the depth of the waterways.
