Prague Virtualization and 3D data model



The impulse for creating Prague Virtualization System was the fact that Prague currently does not have a tool for working with spatial data in expanded reality that would provide a lucid visualization of simulations and prediction of events in 3D. The system is of a crucial importance within the framework of Smart Prague, enabling a commanding and integrated view of the territory through intricate yet user friendly data inputs thus allowing decision making based on transparently processed data. Besides creating a virtual twin of Prague the project also aims to incorporate in the system pilot data on environmental and traffic conditions in Prague.

The Prague Virtualization System is being developed with the participation of representatives of leading Czech research institutions. In developing the system ICT Operátor also cooperates with the Czech Institute of Informatics, Robotics and Cybernetics. It is one of the major collaborative projects of this leading world institute with Operátor ICT. Thus, Prague Virtualization System will build on the ERC AI4REASON Artificial Intelligence for Large-Scale Computer-Assisted Reasoning research project, in which the Czech Institute of Informatics, Robotics and Cybernetics is engaged in. Other academic partners of the project are the Institute of Computer Science of the Academy of Sciences and the Faculty of Transportation Engineering of the Czech Technical University. In addition to the academic sector, a number of Prague companies and Public-benefit organizations also participate in Prague Virtualization System. During the development of key components of the Virtual System, Prague gave the opportunity to the grey dot startup, which brings together young enthusiasts and experts on augmented reality technology on the Prague scene.

A key partner to Prague Virtualization System is the Prague Institute of Planning and Development, which manages the 3D material model of the capital city. Prague Virtualization System uses the 3D material model as its core source while it develops it further, utilizing other technologies with emphasis on practical applicability within the Smart Prague strategy framework.


Once completed, Prague Virtualization System will provide a tool for a more efficient control in diverse situations inherent to the capital, including:

  • Spreading of hazardous substances
  • Flooding and spreading of the flood wave
  • Modeling and optimizing of traffic
  • Modeling the impact of urban development
  • Air and emissions flows, ventilation
  • Evacuation and escape routes
  • Impacts of noise spread
  • Accessibility of constructions using high-rise operation technology
  • Price maps and heat modeling of Prague
  • Modeling of environmental changes and their impact on inhabitants
  • Display of real-time sensor data, and more



Prague Virtualization System will allow:

  • Spatial analysis of events – reverse analysis and simultaneous view of the event from many observation angles.
  • Display of mass and functional variants of building and development projects in the context of a surrounding built-up area; visualization of the impacts of such schemes on the environment in terms of transport, the environment, or the behavior of people in space.
  • Visualization of predictive models based on analysis compiled from a historical data set.
  • Visualization of required model solutions for certain situations based on parameter change.
  • Modeling of a spread of different activities in a given area, featuring primarily the "real-time" option.
  • Spatial time modeling in cooperation with several management bodies and security forces, especially for crisis situations.
  • gallery


  • Support of urbanization strategies‘ impact analysis
  • Possibility to analyze the daily life of the city, respond to current needs or crisis situations (floods, water, gas etc. leakage in the territory and others)
  • Effective collaboration of several management bodies and security forces through spatial and time modeling




A tender dossier processing and the necessary preparatory steps were taken during 2017 to implement the project. The implementation phase began at the beginning of 2018 and includes opening of the Prague Virtualization Laboratory, where the necessary steps are being taken to integrate data into the virtual model of Prague.
