There are two next generation 3D city models of Helsinki available: a semantic city information model and a visually high-quality reality mesh model.
You can view the 3D city model and download its information at . You can find more information here .

The city information model

The 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 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.

  • online service platform Cesium
  • database postgreSQL / postGIS
  • database schema 3DCityDB
  • data model CityGML 2.0

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 Energy and Climate Atlas

City of Helsinki compiles all energy-related data on its building stock into a 3D map application labeled Helsinki Energy and Climate Atlas Executed on the CityGML data model, the semantic 3D city model of Helsinki is part of the city’s toolkit for climate action and climate change adaptation.

The Energy and Climate Atlas is based on the city information model. It contains plenty of building-specific basic information, energy and repair data, as well as data on the consumption of water, district heating and electricity. The Atlas shows you an approximate energy consumption estimate for nearly every building in Helsinki.

The data is available as open data as an excel file and the metadata of the file is available here (in Finnish).

The model also includes calculations of the solar energy potential of all roof and wall surfaces in Helsinki, i.e. how much solar radiation energy surfaces receive per year and per month. All in all, the model includes information on nearly a million surfaces. View the Solar Energy Potential model

The reality mesh model of Kalasatama (2017)

The 3D model of Kalasatama area is a new and more detailed mesh model based on aerial photographs taken in summer 2017. View the reality mesh model of Kalasatama with web browser: . You can download the model in DAE, FBX OBJ, 3D Tiles and 3MX/3SM formats. View more information about the data here.

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 the Unity game development engine, 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 OBJ and 3MX formats. The 3MX files can be viewed in the Acute3D-Viewer application. Other applications that can make use of the mode include Blender and MeshLab, as well as several CAD and GIS applications.

The model is licensed under CC BY 4.0.

Munkkiniemi-Haaga 1915 model

The miniature model of Eliel Saarinen’s Munkkiniemi-Haaga plan from 1915 has been converted into a virtual model. In keeping with the original miniature model, the virtual version is quite accurate and even includes building windows. Saarninen’s impressive city district plan was very notable at the time of its creation. Though it was never implemented, the plan can now be easily viewed by anyone.
