Summary
[edit]
| Description |
English: Depicted baseline of the survey points of a saxonian trignonometry net as shown on an projected map of that time. The net consists of two endpoints, one near Quersa, station 32 (blue), the other near Raschütz, station 34 (red), the base' middle, station 33, is on a privately owned airfield formerly used for military purposes. The base' middle ground survey point was lost, but reconstructed in 2006. Unfortunately the new granit pole is not exactly at the same spot the old one was. The image is part of a larger attempt to reconstruct a good approximation of the original position by using the old maps. Distances of markers are given in meters and pixel width.
