for Digital Built Britain (デジタルツインと情報マネジメントに関する原則整備) Docklands area in Dublin, Ireland 1 3 ing of the digital twin of the city was realized by the com- pany Blindflug Studios with the game “(re)format Z:”, a game about the Reformation in Zurich (Fig. 5). The history of the Reformation is embedded in a dystopian cyberpunk version of the city. In this way, people who would oth- erwise not be interested in the topic are to be addressed. It has been decided to create the game in 3D as this is the best choice for an immersive experience. To be able to complete the project “(re)format Z:” within a short time- frame and to ensure that an accurate representation of the city is created, the 3D buildings of the City of Zurich have been used. The model contained the external shape of the houses including the roofs and the elevation data of the ground. A high degree of detail was to be achieved. The building data have been used as a basis. The detailed version has been created directly on the model, with a newly developed system, which allows the multiple reuse of elements such as windows and doors. With the “toolbox” of about 100 indi- vidual components the centre of Zurich’s old town, including The Geoportal simplifies the collection and assembly of spa- tial data. The desired topics can be selected for certain areas and then automatically requested. Currently, more than 200 spatial data sets are available in raster and vector format. The geoportal enables the systematic and automated viewing of all geodata on the Internet. Also, the automated update of data and metadata and the connection to the OGD portal are guaranteed. The customer can order not only urban but also canton’s data via a “Single Point of Contact”. The geoportal is online since the end of 2019 (GeoPortal 2019). 5.4 Zürich Virtuell (Virtual Zurich) Virtual Zurich opens a window (viewer) on the digital twin. The viewer is intended to facilitate the visualization of 3D components. In the future, the 3D models can be viewed and used interactively in the Intra- and Internet via a web inter- face (Fig. 6). The requirements of the GIS City of Zurich are incorporated into the implementation. In addition to public access, there will also be exclusive rooms.
