Sažetak
Many countries in the world have created virtual 3D models of their major cities. Existing 3D model of the City of Zagreb, capital of Croatia, was created in the period 2007- 2008 based on aerophotogrammetry. It is a vector model consists of Digital Building Model (DBM) and a Digital Terrain Model (DTM). DTM is represented as a triangulated irregular network (TIN). The data were obtained from the photogrammetric mapping of roofs and DTM, defining and measuring the planes of roofs, facades and the ground that together make a 3D city model. The level of details corresponds to LOD 2 according to CityGML standard. 3D city models have become nowadays an increasingly important source of spatial information in different domains. An accurate and well organised 3D model of a city is the principal tool not only for modern urban planning, but also for disaster management, asset management, environmental monitoring, tourism, etc. With the growing interest in 3D modelling, the need for high quality data has arisen. This paper gives the analysis of the data quality of existing 3D model of the City of Zagreb in accordance with the ISO 19157:2013 Geographic information - Data quality standard. Data quality is being analysed using the defined data quality elements: completeness, logical consistency, positional accuracy, temporal quality, thematic accuracy and usability. Since the original 3D model was created in an old Croatian Coordinate Reference System (CRS), data were also transformed in to the new CRS and stored in CityGML format.
