> Hello Blaženka, > > > So, I would like to know is there a way to import fixed points with known variances in JAG3d and adjust the network in a way that these variances affect the results of the adjustment but the imported fixed points remain unchanged? > > No, there is no way because this contradict each other. You assume that the points have uncertainties. That means, the positions are only known to a certain extent, i.e., the points are improvable and, thus, not perfectly known (is not fixed). > > In some federal states in Germany, a dynamic network adjustment (a network with stochastic points, as you mention) is performed as a final adjustment step to check the reference points for changes (e.g. outliers). If the point changes are insignificant, which means that the deviations are - let say - of random nature, the new adjusted positions are not transferred to the database or to the map (i.e. the new position is discarded). > > Kind regards > Micha
