Chisel cross
A chisel cross or chisel mark is the marking of a point mainly in stone material, mostly for the purposes of measurement . It is used in particular for boundary marks and trigonometric points .
As the name suggests, it used to be mostly chiseled into stone, concrete, asphalt or walls with a hammer and chisel. It was later made by two cross cuts on a power cutter . Since the use of border bolts with special dowels for use in inaccessible places such as corner walls, the usage has decreased. For new and re-measurements, it is hardly used any more and is i. d. Usually replaced by other forms of labeling. If it has been included in the real estate cadastre by a land surveying office , the chisel cross is still valid. Some SAPOS reference points for checking the accuracy of GPS receivers, for example in Rhineland-Palatinate, are marked with chisel crosses.
In the mountains, chisel crosses are also cut into suitable rock as secondary or eccentric points in order to be able to reconstruct trigonometric points in the event of possible destruction.
