Our entire virtualcitySYSTEMS team is very grateful and proud to have been recognized as the winner of the  OGC CityGML Challenge at the OGC Toulouse Meeting from November 18th to 22nd. Our CTO Claus Nagel joined the award ceremony in Toulouse and presented our prize-winning solution. A big thank you goes out to all sponsors and jurors of the challenge as well as to OGC for the development of geospatial standards on top of which we build our applications.


OGC CityGML Challenge - Verleihung

In late October 2019, the Open Geospatial Consortium (OGC) CityGML 3.0 Challenge, sponsored by Ordnance Survey, the Manchester City Council and the Triangulum EU project, was held in Manchester for the first time. The aim of the OGC CityGML Challenge was to develop software solutions that support the upcoming version 3.0 of CityGML as well as the integration of dynamic sensor data.


CityGML models are used successfully around the world, and most major cities and national surveys in Germany rely on this OGC standard for processing, managing and sharing 3D geodata. North Rhine-Westphalia, Thuringia, Berlin and Hamburg as well as further cities provide CityGML models as open data.


virtualcitySYSTEMS, HFT Stuttgart and CSI Piemonte were the finalists in the OGC CityGML Challenge in Manchester and developed solutions with a strong commitment. Manchester provided a range of datasets including building, terrain and sensor data in formats such as CityGML, Shapefile or GeoJSON.


All participants showed with their work the great added value that CityGML models and open standards have over the pure visualization of urban and regional models. The presentation of semantic information that is possible with CityGML and the open integration of thematic and planning data will be indispensable in the future.

virtualcitySYSTEMS convinced the jury with their intuitive 3D web viewer and their innovative solutions for creating and presenting planning scenarios in the city model, exporting CityGML 3.0 to many common 3D formats, editing attributes in real-time as well as with the solar potential analysis that was conducted and integrated into the model. For the coming year, the application will be publicly available for innovation purposes.

Looking forward seeing you at INTERGEO 2019 in Stuttgart from September 17th to 19th! You will find virtualcitySYSTEMS in hall 1, booth C1.053. We are very excited that a large number of our customers and partners are exhibiting at Intergeo this year, such as Aerowest, Point Cloud Technology, SIS.TER and M.O.S.S.

With our team we are on site and demonstrating all new product features of virtualcitySUITE and virtualcityPLANNER, as well as solutions for urban simulations, storytelling and BIM.

Title: "Vom digitalen Zwilling über Sensoren zur Simulation"


At the end of 2016, the entire semantic 3D city model of Helsinki was intruduced to the public. The CityGML model, which is available as Open Data and contains more than 77,000 semantic 3D buildings, has now been enhanced with solar irradiation per building. The new Helsinki Climate and Energy Atlas bundles all energy-related topics in a free public interactive 3D map application. The energy values were determined from the semantic information of each 3D building model and stored as additional attributes, as well as building texture.




Enni Airaksinen from the City of Helsinki says: „we are really amazed how nice these textures look like. In the picture, the Helsinki Olympic Stadium’s solar potential is showing clearly! Thank you, and special thanks for inventing the solar energy potential calculation.”


The technologies, tools and infrastructure components behind the 3d map application as well as the semantic 3D city model used by the city of Helsinki come from virtualcitySYSTEMS in Berlin. The analysis of the solar irradiation was based on the CityGML data. Each building (incl. roof and wall surfaces) was enriched with monthly irradiation values and a dedicated CityGML appearance. Unnecessary conversions to third-party formats are obsolete due to the direct processing in the CityGML format.

A particularly high added value is created by the query functionality of the energetic attributes of each building. For example, the user can easily perform a database query via the web based 3d map application to highlight buildings with high irradiation values.

Open Helsinki Energy and Climate Atlas

During Hamburg's 7th International Building Forum 2019 (August 19th – 24th) over 65 national and international urban and landscape planners, architects, mobility specialists, students and city representatives were working in interdisciplinary teams on new creative ideas and concepts for Hamburg's transit.

The open design and ideas workshop were focusing on Hamburg’s “Magistralen” (arterial corridors) to find new ways to transform the large arterial roads from rapid transport of people and goods to previously unthought-of uses. We were very excited supporting this fantastic event and to see our new urban planning solutions as part of the Digital Labor in action.


Last year we launched the urban planning tool virtualcityPLANNER. Now we are taking it to the next level. As of January 2018, we have expanded our operations to include Urban Simulation.


The new Urban Simulation business segment draws from the experience gained over decades of cooperation with CADFEM GmbH, one of the leading experts in numerical simulation. Both companies are subsidiaries of CADFEM International GmbH.


We has been awarded a third managing director with the new department Urban Simulations. Dr. Stefan Trometer - formerly Business Development Manager of Cadfem GmbH - will head the Urban Simulations division. In terms of personnel, the segment will also be strengthened by three new employees. The branch office is located in Grafing near Munich.


By combining our efforts, bringing together the know-how of both companies, it is our aim to offer new applications and services to the market. The synergy of 3D city models and numeric simulation, clearly distinguishes virtualcitySYSTEMS from pure geo-service providers.
