City of Helsinki Advances 3D City Initiative with Bentley’s Reality Modeling

The City of Helsinki is mid-way through an initiative to capture the city and create a new 3D city model that is scheduled to be completed in 2017. Helsinki has a long tradition of 3D city modeling, dating back to the 1980s. Helsinki wanted to update its current 3D city model with new, innovative applications that could provide entire city modeling capabilities in order to improve its internal services, promote smart city development, and share data through an open format for citizens and other agencies. Helsinki also wanted to create a pilot portfolio to showcase the power of reality modeling in coordination with local universities to generate interest in academic organizations.

This EUR 1 million project used Bentley applications to encourage commercial research and development and public engagement. For example, the city used Bentley Map to create accurate base maps and geo-coordinate utility networks. It also used Pointools to pre-process laser scanning data, Bentley Descartes to integrate oblique, raster files, and orthophotographic images into its infrastructure workflows, and Bentley Navigator for clash detection and design reviews. Reality modeling applications the city used included ContextCapture for the entire city mesh model and Bentley LumenRT to enliven designs. Lastly, the city used ProjectWise for collaboration and managing all the data that would be uploaded to a Web portal for distribution and general access.

The unique nature of this project ensured Helsinki would share data internally and externally. External agencies requesting the 3D city model included 3D plus and 3D GPC – a flagship, low-carbon program that looks at the benefits of 3D modeling as opposed to other methods. Helsinki is also sharing this data with the Technical University of Munich as part of its Solar Energy Potential program.

By utilizing Bentley’s reality modeling applications, the City of Helsinki has opened up its data to a host of internal and external stakeholders. This has ensured Helsinki is at the forefront of smart city initiatives, including collaboration with the Open Geospatial Consortium on smart-city programs across Europe.

Jarmo Suomisto, architect, project manager, Helsinki 3D+, said, “The advanced capabilities inherent in Bentley applications facilitated our ability to promote smart city development and improve our internal services. Using this technology allowed us to create innovative city models and make well-grounded decisions.”
