Evaluation of Compatibility among Network Adjustment Software - Results from the JAG3D software package

Together with colleagues from Conservatoire National des Arts et Métiers (CNAM), European Organization for Nuclear Research (CERN), and School of Management and Engineering Vaud (HEIG-VD), we evaluated the compatibility among network adjustment software packages. A detailed description of the procedure and the results was presented at the 5th Joint International Symposium on Deformation Monitoring JISDM 2022. We compared the results of several geodetic networks using software packages developed by the authors' institutions, namely Compensation de Mesures Topographiques (CoMeT), Logiciel Général de Compensation (LGC), Trinet+ as well as JAG3D. Moreover, we included further commercial software packages such as Columbus, Geolab, Move3 and Star*Net. The networks differ mainly in their extent, i.e. the side length and the height. Whereas the smallest network is about 30 m, the largest network under consideration is about 40 km. The height component varies in a range from 30 m to 2.5 km. The raw data and the obtained results can be found on the official CNAM website comet.esgt.cnam.fr/comparisons. This data set contains the raw data, the JAG3D database as well as the adjustment results.本团队与法国国立工艺学院（Conservatoire National des Arts et Métiers, CNAM）、欧洲核子研究中心（European Organization for Nuclear Research, CERN）以及瑞士沃州管理与工程学院（School of Management and Engineering Vaud, HEIG-VD）的同仁合作，对多款网络平差软件的兼容性开展了评估。相关实验流程与研究成果的详细阐述已发表于2022年第五届变形监测联合国际研讨会（5th Joint International Symposium on Deformation Monitoring, JISDM 2022）。本次研究对比了各参与机构自研的多款平差软件的计算结果，包括Compensation de Mesures Topographiques（CoMeT）、通用平差软件Logiciel Général de Compensation（LGC）、Trinet+以及JAG3D；同时纳入了Columbus、Geolab、Move3与Star*Net等商用软件。本次评估涉及的大地测量网在尺度（即边长与高差）上存在显著差异：最小测网的边长约为30米，本次评估的最大测网边长可达约40千米；高差范围则覆盖30米至2.5千米。原始观测数据与最终计算结果可于法国国立工艺学院官方网站comet.esgt.cnam.fr/comparisons查询。本数据集包含原始观测数据、JAG3D数据库文件以及平差计算结果。
