Sažetak
City of Zagreb has been developing 3D city model for spatial planning since 2008. The initial 3D model was created by photogrammetric mapping with Level of Detail 2 and later updates were made using airborne LiDAR data and UAV photogrammetry. City spatial planning sector was detected as the main user and developer of value added applications, while more users were detected in the fields of emergency management, environment protection, energetics, risk management etc. Web App ZG3D for browsing, viewing and using 3D data was produced and presented in 2016, based on the existing 3d city model and considering the guidelines from previous studies. ZG3D integrates 3D data on existing buildings with 3D and 2D data layers from the fields of urbanism, architecture, topography, geotechnics, public green spaces, heritage protection, urban renewal and statistics. The aim of the project is to use and develop 3D city model in the city administration, education, science, economy, civil society and other applications. Application of 3D city model in spatial planning of the City of Zagreb so far may be classified as 3D overlay in master land use planning, 3D building zoning in detailed land use planning, 3D modelling of new buildings during architectural competitions and 3D modelling of building interpolations in protected city core. The 3D city model has also been identified as one of the fundamental databases in the post- earthquake reconstruction process. The City of Zagreb plans to upgrade the existing 3D city model and the ZG3D application towards the digital city twin. The main issues are upgrading and updating 3D building data and integrating live information about urban processes and activities within the 3D model of the city. With model improvements and integration with real-life data, the impact on city planning and management is expected to be even higher.
