The 3D city model provides the basis for both new applications. The most popular freely accessible geodata set of the city of Zurich has been downloaded from the geoportal over 4500 times since the end of 2018. Now this data can be easily displayed in a playful way. Users can, for example, measure the height of the buildings shown or call up further information on them at the click of a mouse.
Both applications are primarily aimed at all actors in the building sector: planners, architects or engineers. The numerous visualisation and analysis options make it possible to work at different scales – from the overall city view to the detailed building model. The underlying technology is already used within the administration for the visualisation of noise simulations, in the context of architectural competitions or for the integral representation of civil engineering and building construction projects.
However, the apps are also intended for use in schools or for the documentation of real estate and ultimately for everyone. “Zürich virtuell” and “Zürich 4D” were developed as part of the city council’s “Digital City” strategy focus and are part of the so-called “digital twin”, the digital representation of the city of Zurich. Further offers can be integrated into the developed digital infrastructure on an ongoing basis.
