Overview: The city of Helsinki created a digital twin of the entire city, which will help them meet modern challenges while improving internal services and processes.

Be Inspired Award Winner, 2016, Innovation in Reality Modeling

Taking on Modern Challenges with a City-scale Digital Twin

As the city of Helsinki faced modern challenges such as increased urbanization and climate change, the government knew they needed to go beyond traditional planning techniques to best serve their community and meet Finland’s goal of carbon neutrality by 2035. The city government launched a EUR 1 million project to produce a digital twin of the city to improve Helsinki’s internal services and processes, promote smart city development, and share city models as open data to citizens and companies for research and development. As part of Helsinki 3D+, the project team delivered a pilot portfolio to demonstrate the power of new modeling technology and promote its use in higher education.

Collaborative Approach to Modeling Terrain

The city of Helsinki used a combination of laser scanning and oblique photogrammetry to acquire data and images for the project. Leveraging ContextCapture and a host of Bentley 3D reality modeling applications, the team modeled the surface and terrain and generated a reality mesh model of the entire city. Additionally, ProjectWise served as the collaborative interface to manage all information and share data across internal and external teams.

Bringing the Digital Twin Together

The city of Helsinki used Bentley’s reality capture technology for geo-coordination, optioneering, modeling, and visualization throughout the Helsinki 3D+ project. For large-scale base maps and utility maps, the team used OpenCities Map. They relied on Descartes to process oblique and orthophotos, Pointools to model the surface and terrain, ContextCapture to create the 3D mesh representation of the city, and LumenRT for visualization to present the models. Using ProjectWise as the common environment for all project data optimized document management and streamlined workflow among internal and external teams.

Promoting Smart City Development

The city-scale digital twin provides a holistic approach to decarbonization, resilience, healthy communities, and well-being. Helsinki 3D+ now supports many types of initiatives to improve sustainability and quality of life, including analyzing solar power utilization, conducting flood assessments, and performing noise calculations. These initiatives provide deeper insight into the state of city systems, improve decision-making, and promote smart city development. The city also uses it to improve planning and engagement between the city, residents, and developers, ensuring everyone’s voice is heard. Project Playbook: ContextCapture, Descartes, LumenRT, OpenCities Map, Pointools
