One of the key themes of HIC 2019 Conference is strengthening the role of cities as innovation platforms. Digitalization is shaping the world at a fast pace. Therefore, European cities must take an active role in utilizing all the possibilities brought forward by new digital technologies. One of these possibilities is 3D city modelling.

 Helsinki has been developing an intelligent 3D city model for some time already and there are two next generation 3D city models of Helsinki available: a semantic city information model and a visually high-quality reality mesh model.  

The Helsinki city information model allows users to perform a variety of analyses focusing on energy consumption, greenhouse gases or the environmental impacts of traffic, for example. The reality mesh model can be utilised in various online services or as the basis for all kinds of design projects.   

The models are available as open data.

Utilise the models and develop new services 

Here are two videos that showcase different uses of the next generation 3D models Helsinki has developed. The former presents Helsinki’s maritime environment and the latter new project areas and suburban neighbourhoods of Helsinki.  

Helsinki’s maritime location is part of its fundamental nature and appearance 

Opening the shoreline has long been one of the guiding principles of Helsinki’s city planners, and in the future new maritime city districts will provide the city with more waterfront housing and leisure venues.  

In Helsinki the downtown area is located on a peninsula and densely built, while the rest of the city is spread along shoreline. The city area also covers a vast sea area and over 300 islands. 

The new 3D-video offers a unique opportunity to see the magnificent Helsinki waterfront and archipelago from an aerial perspective.

Helsinki 3D city models: tool for visualizing and analyses 

The video showcases three diverse development areas of Helsinki: the eco-neighbourhood of Kuninkaantammi in northern Helsinki, the maritime district of Hernesaari and the Crown Bridge and the new residential area of Kruunuvuorenranta overlooking Helsinki city center. When finished in 2026, it will be the longest bridge in Finland and serve trams, cyclists and pedestrians.  

From Kuninkaantammi to Hernesaari we fly over the Central Park, a unique forested area of 1 000 hectares. In addition, the video introduces wind simulations and solar energy potential analysis, both made possible by the state-of-the-art 3D model of the city.
