Possibly Prevented Keileem

This is the maximum limit (distribution) of keileem in Drenthe. Outside the confinement of the keileem on this map, the keileem is not present. Within the boundary of the keileem on this map, keileem can be found in the subsurface, however, this can only be said with certainty in the places where a bore has actually occurred and keileem has been found. This dataset is an interpolation of the drillings from the dataset ‘Prevent keileem (borings)’.
