+=====  Geodetic networks and point types =====
+This tutorial focuses on the point types supported by JAG3D. A leveling network is adjusted using known reference points (forced network), and using stochastic points (dynamic network). The differences between the point type are demonstrated.

+=====  Deformation analysis =====
+A deformation analysis (congruence analysis) is performed based on the raw observations of a small leveling network using the software JAG3D. The stability of the reference network - the datum points - is analysed using hypothesis testing within a free network adjustment. According to the DIA approach, a misspecified functional model is detected and an unstable datum point is identified. In the adaptation phase, this point is treated as object point - not defining the datum. Moreover, shift parameters of object points are derived.
