Geneva 3D

Arnaud Ricci’s #Geneva3D assembles dozens of geodata sources into a real-time model of the city, animating weather, lighting, transport and traffic. The app also ships a 1850 reconstruction of Geneva, letting you time-travel through the same interface. #digitaltwin

Over the last few months1 and in his spare time, Arnaud Ricci has been developing Geneva 3D, an animated and interactive 3D model of Geneva, Switzerland. Geneva 3D combines dozens of geodata assets in a performant and visually appealing 3D web app.

Lighting conditions, weather, public transport including aviation, and road traffic are shown in real-time – based on real-time data or on modelled data, the latter for road traffic. Data comes from the SITG2, opentransportdata.swiss, Open-Meteo, eautemp.com, OpenStreetMap3, the FOEN4, the SED5 and ETH Zurich, Mapzen, and swisstopo6.

The app also features a reconstruction of Geneva in 1850:

Geneva 3D is available in English, French, German, and Italian, and features a guided tour (the “Presentation” button), which is a good way to familiarise oneself with its functionality. As far as I could see, the code is not open source. On LinkedIn, Arnaud posts about his progress and the feautures of Geneva 3D.
