Acquisition and Modelling of Indoor and Enclosed Environments

Indoor modelling gains increased attention in the last decade. Several factors contribute to this interest. First of all, the cities are getting larger as a concurrence much more people spend their time indoor. According to last investigations 75 % of the population lives in cities and about 87% of the time is indoors. The building environments are getting more complex. The progress of architecture and construction research and developments has made possible a huge non-regular building complexes to be built, such as museums, airports, stadiums and shopping malls. Management, security and guidance in such environments cannot be completed with traditional 2d methods. Therefore a lot of research has been dedicated to indoor modelling but in isolation and dedicated to specific applications.

Indoor space differs from outdoor space in many aspects: spaces are smaller; there are many constraints as walls, doors, stairs, furniture. To be able to represent indoor spaces in a proper way many data acquisition concepts, data models, and standards should be redefined to meet the requirements of indoor spatial applications. The acquisition, modelling of and navigation in indoor and enclosed environments are research activities that have received great interest in recent years. These activities are by both 1) advancements of acquisition systems, photogrammetry and computer vision, modelling, mobile computing and augmented systems, an 2) demand by indoor application systems such as positioning and navigation or facility management to name a few.

This increased research activity has been matched by industry that has invested in commercial and open source applications. However the research is still very fragmented and application-specific. Therefore, we started a series of conferences dedicated to the topic of indoor 3D.


  • To promote and advance indoor modelling and navigation research within the ISPRS community.
  • To examine and evaluate the state of the art in all aspects of indoor modelling and navigation.
  • To examine and evaluate the application of indoor models for navigation, crisis decision support systems, simulations, information systems, and augmented systems.
  • To share best practices, discuss user requirements and explore opportunities for future research directions.
