Abstract

The first 3D model of the city of Zagreb was developed in 2008. Since then, the model has been improved and updated. Today, it is used for various purposes in the city planning and management. It is also publicly available to citizens through the ZG3D Web application. In this paper, an assessment of the existing 3D model is provided by considering different factors (i.e. consistency between models, standardization, data quality, data interoperability, data maintenance/governance, and use cases) that need to be tackled in order for the 3D city model to be further improved and used towards the creation of the digital twin and ultimately to support the smart city concept. The assessment considered some general criteria and also the 3D City Index assessment tool developed by the Urban Analytics Lab, National University of Singapore (NUS). The assessment results show that the existing model is used for various purposes, but to evolve towards a true digital twin, it must be improved.
