Distance between reference points: approx. 15 meters.
The northern point is often hidden under leaves and needles.
In a mining area like Getön, where many mines are clustered closely, the surveyor’s work was crucial and required high precision.

On mine maps, this point is marked as ±0.0.
From this point, the elevation for the following was determined:
Mine shafts
Stopes
Tunnels
Other important parts of the mining system
