4D Objects-By-Change (4D-OBCs, Anders et al., 2021) derived from the Noordwijk permanent laser scanning (PLS) dataset (Vos et al., 2023). Descriptive features have been derived from the 4D-OBCs and stored in a Pandas DataFrame (df_objects.pkl). This DataFrame is used to organize and cluster similar 4D-OBCs that describe particular types of sandy beach surface dynamics (df_objects_grouped.pkl).

Refer to the README.md file and source code for the details on how to reproduce and process the dataset.
