Two BSc theses on the extraction and classification of dynamic objects in the Noordwijk permanent laser scanning dataset

Large dynamic objects on the beach of Noordwijk, Mark Geerearts 2025

Students Sidi Liu and Mark Geeraerts finished their bachelor’s Applied Earth Sciences in great style. Both of them worked on the Noordwijk permanent laser scanning point clouds. Mark developed methods to automatically extract dynamic non-natural objects, like bulldozers, bikers, humans, and ladders, whereas Sidi worked on an automated way to classify these objects into bulldozers and others. Both of them obtained great results: more than 93% of the large dynamic objects (e.g., bulldozers) could be detected using Mark’s methods, and more 92.5% of these could be correctly classified by Sidi.

New PhD candidate on the AdaptCoast project

Posted on by

From the start of this year onward I, Daan Hulskemper, will be working on the AdaptCoast project as a PhD candidate at Delft University of Technology. My background lies in earth surface processes, and optical and laser remote sensing. After getting my Bachelor’s degree in Earth Sciences at Utrecht University, I did my Master’s at Delft University of Technology, in Geoscience and Remote Sensing. Here I graduated on the detection and classification of surface change dynamics in the point cloud time series acquired at Kijkduin (link). I look forward to further dive into this topic as part of my PhD journey.

My first duty as a PhD candidate will be to further explore methods for automated extraction and characterization of surface change dynamics from point cloud time series, acquired with the permanent laser scanner setups at the various CoastScan locations. Thus, expanding the knowledge and applicability of the data acquired as part of CoastScan. We will also enrich these datasets with LiDAR data acquired with a drone, and possibly other sources. Additionally, I will look into the prediction of topography changes under variations in human and natural forcing; exploring the causalities between the forcings and consequent short-term surface dynamics on the beach.

New publication of data set from Noordwijk:

S. Vos, C. van IJzendoorn, R. Lindenbergh and A. de Wulf published a part of the CoastScan data set as processed for the research article: “Asynchronous dune development on a Dutch urbanized beach due to buildings and other anthropogenic influences” via 4TU.ResearchData

Noordwijk Data Set Published

Posted on by

The entire PLS data set acquired in Noordwijk between 11 July 2019 and 21 June 2022 is now published via 4TU.ResearchData. The data set contains all point clouds from the hourly scans available over the three-year period. Each point cloud contains a ~1km long part of the coast (dunes and beach) in front of Grand Hotel Huis ter Duin in Noordwijk.
