Boundaries in agricultural areas and in forests are mostly made visible by boundary stones (formerly also known as landmarks) that are frost-proof (i.e. at least 60 cm) in the ground. In the city, borders are usually on walls, fences or the lines of buildings . Here z. B. also used chisel marks . The breakpoints of borders were often marked in earlier centuries by border or marrow trees . Oak, beech or linden were often used for this, because these trees are very old and difficult to cut down. Especially the deep-rooted oaks can only be removed with great effort, which prevents a borderline from being deliberately changed.

The accuracy with which the boundaries are measured by the geodesist depends on the respective provisions of the federal states. Usually there are different accuracy classes. In (e.g. inner-city) areas with high property values, the permissible deviation can be lower. In the newer cadastre , every survey is based on the uniform reference system of the national survey , in older operations it can also be local. The exact height of boundary points is generally not determined.
