Since 2014 the city of Hyvinkää (in the Southern Finland) has actively innovated and piloted browser based 3D working methods for urban planning. Hyvinkää has implemented automated processes to integrate building information models (BIMs) to a browser based 3D city model and integrated 3D city model also to Lupapiste.fi, which is a nationwide service to apply building permissions. In 2017 Hyvinkää organized a browser based 3D architecture competition as a KIRAdigi project in co-operation with a Finnish technology company, Sova3D Ltd.
In 2018 the city of Hyvinkää continues to innovate new ways of using browser based 3D city model. Hyvinkää is piloting a browser based 3D platform for collaborative urban planning. The project will be carry out as a new KIRAdigi project in co-operation with two Finnish high tech companies, Sova3D Ltd and Terra Solid Ltd and three real estate and construction companies. The three companies all have plans to start construction projects in Hyvinkää city centre in the near future.
In our presentation we will first describe how a high quality 3D city model is created by fully automated processes by using point cloud data, oblique photographs as well as ortho photos. (The result can been seen in Youtube: 'Hyvinkään keskustan 3D-malli').
We also consider the quality requirements for the 3D city model when publishing and sharing it via the Internet. Special focus is paid to achieve high quality viewing experience from the street level. In our presentation we describe how the buildings are textured with building facade photographs.
Then, we describe how the browser based 3D city model can been used in collaborative urban planning. The different organizations of the city, several facility management and construction companies can all publish their 3D plans in browser based 3D city model. In addition, citizens can give their own ideas by drawing 3D features via easy to use 3D user interface. All parties can discuss about 3D plans via Facebook, which is integrated to the 3D platform.
Finally, we describe how users can view the future 3D plans via a smartphone (in certain locations).
