Abstract
Nowadays, geodetic networks have a significant contribution in safety during constructing and operation in urban constructions. They could prevent a terrible disaster by detecting and alarming any displacement in important constructions. The detection of unstable and stable points is an essential part in computing displacement in geodetic network, because misdetection leads to datum defect in geodetic network. Then, the detected displacement will be questionable. In order to detecting stable and unstable points usually two important methods are used:A. General stability test in geodetic networks, B. Minimizing the norm of displacement vectors. The main goal of this paper is the comparison between two mentioned methods and assessing their advantage and disadvantage.
