Prague Virtualization and 3D data model



The impulse for creating the 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 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 aimed to incorporate pilot data in the system on environmental and traffic conditions in Prague.

The Prague Virtualization System was developed with the participation of representatives of leading Czech research institutions. In developing the system Operátor ICT 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, the Prague Virtualization System has built 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. Other academic partners of the project were 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, several Prague companies and Public-benefit organizations also participated in the Prague Virtualization System. During the development of key components of the virtual system, Prague allowed 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.


The Prague Virtualization System provides a tool for more efficient control in diverse situations inherent to the capital, including:

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



The Prague Virtualization System allows:

  • 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 behaviour 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.
  • Modelling of a spread of different activities in a given area, featuring primarily the "real-time" option.
  • Spatial time modelling in cooperation with several management bodies and security forces, especially for crises.






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