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 20thInternational Course on Engineering Surveying, 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 generalized 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. Further information are available at the website of the Course on Engineering Surveying.

JAG3D

  • Added redundancy check when determining the quantiles of the variance component estimate
  • Added check of selected projection in relation to project terrestrial observations to avoid nonsensical combinations such as UTM and slope distances
  • Verification that additional group parameters of selected observation groups are defined identically (separately for activation/deactivation state and numerical value)
  • Sign in the functional model of levelling data corrected for instrument and target heights
