The implementation of the legal coordinate cadastre brings up the question in the daily practice, where is the right place for border stones, if the coordinate of “highest accuracy” differs from its demarcation.

The cadastral material in form of sketches has grown over 200 years. This is the reason why every point has a more or less big area of tolerance. If a border demarcation is laying inside that area of tolerance, and if it was acknowledged by the former neighbors, when the border point was installed, then its site cannot be refused statistically.

Its site can only be shifted in that case, if the neighbors confirm that in an official protocol. And even in such a case the shift of the stone must be within the tolerance area. Consequently the Cadastral Authority of Muelheim at the Ruhr has downgraded all its coordinates of highest quality to avoid legal uncertainties by the legal coordinate cadastre. The normal citizen can hardly understand the facts, even if the consequences can be very far-reaching.


To ease the situation for the citizens the Public Appointed Surveyors in GEOHAUS are called upon to give more information in the topological sketches belonging to the official protocol in form of relative measures to walls or other topographical features. They help the neighbors to have a better orientation about the legal site of the border and the border points.
