This layer gives the interpretation density of the boreholes and probes of Undifferentiated member of the Arenberg Formation, as defined in the Shallow geological 3D layer and voxel model of the Antwerp region (OA v1.1, 2023). The shallow model is a first test case for modelling the shallow urban subsurface within the framework of the management agreement of the Flemish government with VITO, under the name VLAKO, commissioned by the Flemish Planning Bureau for Environment.
