Volumes are calculated based on the thickness of this layer and multiplied with the volume of a voxel (200*200*1m). As a consequence, it are rough estimations. Metadata can be found in the attached QMD file and can be opened in QGIS. The modelling process is described in Hademenos et al. 2019. More information in the final project report: Van Lancker et al. 2019.
