Fixed points LFP3/HFP3

Surveying points form the basis of all data related to space. The so-called fixed points are used for all surveying tasks that require reliable and precise determination. The position and height fixes of categories 3 (LFP3, HFP3) are used to compact the point network and form the basis for official surveying. A position fix point is a permanently insured point with a stone or a bolt (partly under shaft) with known coordinates and possibly known height. A height fix point is a permanent point marked with a bolt with a known height. The commissioned tracking geometer is responsible for the LFP3 and HFP3.
