This tutorial gives a step-by-step instructions about the download and installation of the software, the import of CityGML datasets, the export and 3D visualization of 3D city models in a web browser. Please note that this tutorial does not provide an extensive explanation of the 3DCityDB sofware package itself. If you need more details about 3DCityDB, please refer to the comprehensive technical documentation instead.

OGC CityGML is an open data model and XML-based format for the storage and exchange of semantic 3D city models. It is an application schema for the Geography Markup Language version 3.1.1 (GML3), the extendible international standard for spatial data exchange issued by the Open Geospatial Consortium (OGC) and the ISO TC211. The aim of the development of CityGML is to reach a common definition of the basic entities, attributes, and relations of a 3D city model.

CityGML is an international OGC standard and can be used free of charge.
