-Diagnosis adjustment of planned networks as well as the analysis of existing geodetic networks by means of least-squares adjustment is a principal task in geodetic and metrological sciences such as surveying engineering. The network adjustment yields not only the estimated coordinates and the related fully populated dispersion but also parameters to evaluate the reliability of the network. At the *20th International Course on Engineering*, the principles of geodetic network adjustment are recapitulated within the specific tutorial named *network analysis*. The conference will be held at ETH Zurich from April 11 to 14, 2023. The open source least-squares software package Java·Applied·Geodesy·3D is used to analyse local terrestrial networks, to interpret the adjustment results, and to evaluate network reliability. The principles of Baarda's DIA approach for detection, identification and adaptation of misspecified models are generalised and applied to evaluate network deformations. In complex analysis procedures, the network adjustment is only a cog in the wheel. For that reason, interfaces for data exchange and processing of adjustment results in external applications is addressed. For further information are available at the website of the [Course on Engineering](https://ingenieurvermessungskurs.com).
