Today, the Chair of Geoinformatics of Technical University Munich (TUM) has, together with our development partners virtualcitySYSTEMS and M.O.S.S., finalized and released the new version 3.3 of the 3DCityDB. The 3D City Database is an Open Source software suite featuring solutions for the efficient storage, management and visualization of CityGML based 3D city models. The package defines a relational schema for CityGML for the spatially-enabled relational database management systems Oracle Spatial/Locator and PostGIS. We migrated the entire project from LGPL to Apache 2.0 license for easier inclusion with 3rd party software systems.
The most important new feature is the 3D Webclient supporting the visualization and interactive query of 3D city models of any size in standard browsers such as Mozilla Firefox, Google Chrome and Apple Safari without the need for additional plugins. The web client has been developed by the Chair of Geoinformatics, TUM, as an extension of the Open Source Virtual Globe Cesium WebGL. It also runs on mobile Android and iOS devices (smart phones and tablets). The 3DCityDB exporter was extended to generate data in the visualization format glTF (besides KML and COLLADA, which have been supported already before). The 3D Webclient as well as all other features are comprehensively explained in the extended and completely revised documentation (285 pages).
Many cities around the world, almost all state mapping agencies in Germany, and numerous research projects are relying on the 3DCityDB. For free download of the software, the documentation, further information (including a new PDF flyer), and new online demos please visit www.3dcitydb.org
