H3O-De Kempen — Hydrogeology- Support points Tree Aquitard

Support points are fictitious drilling points that are combined with the drilling points at interpolation to control the depth or thickness gradient so that a logical spatial gradient is obtained. Support points are mainly used in areas with low density of drilling points. The location of a support point and the corresponding depth or thickness of the unit are often estimated on the basis of field knowledge but can also be based, for example, on interpretations from probes. ‘Tree Aquitard’ is a map layer that forms part of the dataset ‘H3O-De Kempen — Hydrogeology’.
