Swiss national levelling network LN02
Swiss national levelling network LN02
The Swiss national levelling network (LN02), dating back to the 19th century, was conceived in 1902 with the definition of the Swiss height system. The first measurement of the network took place between 1903 and 1933, and as of 1943 it was remeasured for the second time. The reference point for the height measurements is the «Repère Pierre du Niton» in Geneva, with a height of 373.6 metres.
