Utilise the models and develop new services

The reality mesh model

The reality mesh model can be used as the basis for design and planning, as a foundation for online services or as an environment in game engines, for example.

The model allows you to measure volumes, differences in height, distances and areas based on the ETRS-GK25/N2000 coordinate systems. The model is dimensionally accurate, as its points are located within 20 centimetres of their actual position.  

The model is available in the OBJ fileformat. Applications that can make use of the model include Blender and MeshLab, as well as several CAD and GIS applications. 

The model is licensed under CC BY 4.0.

You can also use the Helsinki3D-cityloader to download the model easily

The city information model

The city information model includes a terrain model and buildings. Buildings are presented in two formats: flat-roofed (LoD1) and with differentiated roof structures (LoD2). The LoD2 buildings are also available textured. The buildings are all semantic CityGML objects.

Each building has its own identifier (GMLID, RATU and VTJ-PRT) in the database, allowing data streams to be combined.

The model uses the ETRS-GK25 plane coordinate system and the N2000 height system. The accuracy of the city information model corresponds to the accuracy of the city plan base map, meaning that buildings are located exactly where they are in the city plan’s base map.

The city information model 

You can choose the area that you wish to download data for in the data download service. You can also choose your preferred file format and whether to download textured or untextured data. Building property data is not included.

Go to the download service

You can also download the data directly as CityGML files, which are divided into map sheets covering four square kilometres each. The files include building property data.

Helsinki's Energy and climate atlas provides energy information from the entire city area

Helsinki's Energy and climate atlas is a free online application based on the 3D citymodel, which contains information on renewable energy and energy renovations throughout the entire Helsinki area. The atlas is meant for anyone to use: city planners, housing associations, citizens and also companies offering energy solutions. The service has currently four parts: energy information of buildings, the simulated heating requirements, solar energy potential and geothermal energy potential.

Helsinki's Energy and climate atlas contains comprehensive building registry data, so there is diverse information on the heat sources, materials, renovation history, and protection designations of buildings. In addition to this the Atlas has energy consumption data from Heka's buildings, and for every building in Helsinki there are estimated heating, user electricity and building electricity consumption values based on the buildings' ages and sizes.

The Atlas provides simulated data on the buildings' heating requirements and it's change as the climate changes.

The service also contains information on the possibilities brought by renewable energy, for example data of solar energy potential and geothermal energy potential. You can inspect the solar energy potential of every wall and roof surface in the entire city.

Geothermal energy potential is available in the entire city for wells of different depths (100m, 300m or 1000m). In the Atlas there are also background-materials to support the planning process of geothermal wells, such as ground water areas, bedrock features and ground properties.

Helsinki's Energy and climate atlas is a work in progress service. Future plans include microclimate-circumstances and modeling them as well as energy renovation cost estimates. Check out the atlas at it's current state at and Atlas' open data in the HRI-service.

Helsinki's city models as open data

Helsinki’s city models are available as open data from Helsinki Region Infoshare.


These videos showcase Helsinki’s 3D city models, as well as their benefits and possibilities for cities, among others actors.

View the city information model

The city information model allows you to view not only the city’s buildings and information on them, but also the city’s terrain model.

View the reality mesh model

The reality mesh model allows you to examine Helsinki as it was in summer 2015 and visit places that you might not think to go to otherwise.

Helsinki's Energy and Climate Atlas

The Energy and Climate Atlas contains plenty of building-specific basic information, energy and repair data, as well as data on the consumption of water, district heating and electricity.
