The Rotterdam 3D city model – a digital twin
Goodmorning!
1999 – 2006 TU Delft – Geodesie / Geomatics
2007 – 2013 Iv-Infra, ingenieursbureau, Surveyor 2013 – 2018 City of Rotterdam, Advisor Geo-information
Jane Hermans – van Ree
Departement of Geo-Information
Rotterdam
Population (January 2016) 635.305
Surface area 32.416 hectares
Water 11.529 hectares
Nationalities approx. 170
• Second largest city of the Netherlands
• Beautiful city known for its architecture
• Largest port of Europe and 10th worldwide
• Hands on mentality
• and it is my home town!
Department of Geo-information
• Responsible for all object information of the objects in the public space. • Both the location and the administrative object information
XYZ-coordinates and information like year of construction; object type; age etc
• Necessary lots of processes From urban planning to asset management and more
• Different geo-information products and maps • One of them is the Rotterdam 3D City model
Introduction
Rotterdam 3D
Why 3D a model
Development Rotterdam 3D
Ambitions
The 3D city model is easily accessible and used for linking applications from various fields of work. Rotterdam requires a 3D city model which centralizes the users demands.
What do they want; which information do they need? One model for all kind of usage, same base for different projects
Vision of Rotterdam 3D
Foundation for all key
registers
Part of all primary
processes
Usefull for all kind of applications
Open and exchangeable (CityGML)

Rich semantics compared to 3D graphics and 3D map formats Objects know WHAT they are and WHERE they are Hierarchical structure of features and their components Required for sophisticated queries, simulations and analyses

Results so far
Rotterdam 3D a digital twin
New building model LoD1 & LoD2
Object oriented and intelligent
Different objects included Buildings LoD1 & 2 – Terrain – Trees (incl. roots) – Lampposts (#types) – Cables and pipelines

Connection between Rotterdam 3D and BIM A lot more research is needed but this works already
Use Rotterdam 3D for GIS analyses Saving potential // Green roof potential // Solar potentional
Visualize sensor data in Rotterdam 3D Parking spots available or not // Groundwater level
Visualise a new situation in Rotterdam 3D See the impact on the surroundings directly
Pilot BRO in Rotterdam 3D See the interaction between objects in the subsurface and object above the ground
Pilot BRO in Rotterdam 3D There are a lot of objects in the subsurface
Participation using 3D City models Gather feedback on a new plan
• Open and accessible is necessary! • Ownership data (especially with sensor data) • ‘Think big, act small’ (think and ACT!) • 25% technique, 75% culture and organisation
Lessons Learned
Development of the 3D city model continues • Feel free to use our data for projects or research
• www.3drotterdam.nl • Feedback on the data
• There is a lot to learn and there are a lot of questions unanswered :
• Master researches • Internships • Traineeships • ….
