High-altitude points are permanently fixed markings (usually metal bolts) on structures, in the rock or other point beams. The line-by-line official height fixed-point network 1 to 4. Order forms the basis for a uniform height reference system in Germany. Until 30.06.2017, the height reference system in Bavaria is the German main height network of 1912 — DHHN12 (EPSG:7699), from 30.06.2017 it is the German main height network from 2016 — DHHN16 (EPSG:7837). The DHHN92 height (EPSG:5783) is available as an additional height reference system. High-altitude points are given as data sheet (with and without sketch) and as a fixed point overview in the sheet section of the topographic map 1:25 000.
