This thesis provides a theoretical and practical approach to recording commercial public infrastructure (CPI). Structured CPI collections provide crucial information for a number of spatial management processes; the Consolidated Cadastre of Commercial Public Infrastructure is an environment best described as a meeting point for users and owners of the data. Users no longer need to approach the owners and managers of such infrastructure to acquire these data, as the necessary information can be obtained via a common entry point and a single query in the Consolidated Cadastre of Commercial Public Infrastructure.
CPI data in the consolidated cadastre are publicly accessible online, where users can retrieve up-to-date data for the desired parcels of land. In the second part of the thesis, measurements were performed on-site and the heights of characteristic points of the CPI structures so obtained were compared with the heights entered into the records of the public utility company Javno podjetje Vodovod Kanalizacija, d. o. o. (VO-KA). An analysis of the measurements performed on-site and the comparison of the results with the officially recorded heights for the characteristic points of the CPI structures confirmed our reservations regarding the quality of recorded data on utility lines. Correct data on the heights of CPI structures can only be obtained by choosing suitable reference points, and it is crucial to associate them with the benchmarks of state or city-wide levelling networks or all geodetic points the heights of which are measured with a 1 mm degree of precision.
