The 3D City Database project team is grateful and appreciative for the financial assistance and support we received from partners that contributed to the development of the 3D City Database.

Government Technology Agency of Singapore

The Government Technology Agency of Singapore (GovTech Singapore) has been developing a 3D city standard for Singapore based on CityGML, to establish a common 3D representation of the city-state. GovTech wanted to extend the representation to include other city features through the ADE approach, and had worked with virtualcitySYSTEMS GmbH to start the development of the ADE support on 3DCityDB. The intent is to open source the 3DCityDB ADE support to the international community, so as to encourage wider adoption and implementation of the CityGML standard and ADEs.

CADFEM International GmbH

Founded in 1985, CADFEM is one of the pioneers of numerical simulation based on the Finite Element Method and one of the largest European suppliers of Computer-Aided Engineering. Through the Leonard Obermeyer Center of the Technical University Munich, CADFEM supports the research on digital methods for the design, creation and maintenance of the built environment and the work on the 3D City Database. Bridging the gap between simulation systems and 3D GIS / BIM is a key requirement for enabling multi-physics Urban Simulations and for building Digital Twins of the urban space. The CityGML ADE mechanism supports this in two ways: 1) city features can be enriched with data that is relevant for simulations, and 2) simulation results can be brought back into the city model, turning it into a dynamic knowledge base. CADFEM is supporting the 3D City Database project to leverage the adoption and usage of CityGML ADEs in the field of Urban Simulations.

Climate-KIC of the EIT

Climate-KIC is a so-called ‘Knowledge and Innovation Community’ about Climate Change and Mitigation. It is one of three Knowledge and Innovation Communities (KICs) created in 2010 by the European Institute of Innovation and Technology (EIT). The EIT is an EU body whose mission is to create sustainable growth. Most 3DCityDB developments at TU Munich were done in the context of the projects Energy Atlas Berlin, Modeling City Systems (MCS), Smart Sustainable Districts (SSD), and Smart District Data Infrastructure (SDDI), all financially supported by Climate-KIC.
