The Public Utility Cadastre (slov. Zbirni Kataster gospodarske javne infrastructure – ZK GJI) is the central database in Slovenia that contains records on networks and constructed objects of the public utility infrastructure. Mainly public companies that manage networks and objects of public utility infrastructure must fulfil the legal obligation of submitting data about any new construction or change within the existing public utility infrastructure to the ZK GJI. In particular, smaller managers of public utility infrastructure are facing with the challenges of software support that is needed for their work, where they have to meet the state requirements, as software solutions might be a substantial financial burden.
Nowadays, in the age of open-source software solutions, the managers of public utility infrastructure from Slovenia as well as from other countries worldwide, are increasingly seeking for open source software solutions within geographic information systems (GIS). The appropriate software solutions are needed for geospatial data; this is also data on public infrastructure, acquisition, processing and analyses. In this thesis, we present the development of the user interface that establishes an environment for the recording of data on public utility infrastructure. The solution is based on open-source software solutions, such as QGIS and PostgreSQL, that also integrates a possibility to include open geospatial data. To be considered as open-source software, a solution has to meet certain criteria, presented and considered in this research work. This is, in particular, to encourage managers of public utility infrastructure to use such open-source solutions. The solution has been tested on real data. Our conclusion has been that the solution can be used in practice. With this, we have proved that it is possible to develop extension within available open-source software, such as QGIS and PostGIS, which can be used for the recording of data of public utility infrastructure in public cadastres.
