3D City and Infrastructure Information Modelling and Simulation: A Contribution to Collaborative

and Multi-Scale Planning

ISPRS Commission IV, WG IV/7 - Geo-Data Management

Geodetic Institute Karlsruhe Institute of Technology, Germany

Collaborative and multi-scale 3D modelling and simulation are key methods for future Geo- Information Systems (GIS) as well as for Building Information Modelling (BIM). Many advanced GIS and BIM applications inherently depend on geo-referencing 3D coordinates, models, data management, visualization, and analysis. Smart cities, BIM, facility and disaster management as well as subsurface exploration and metro planning, need digital support for collaborative work and multi-scale planning. However, the functionality and dissemination of today´s GIS and BIM environments to integrate 3D data modelling and simulation, is still poor. Therefore computer-aided collaborative and multi-scale 3D planning are challenges especially for complex railway and subway track infrastructure projects in the built environment. Many legal, economic, environmental, and structural requirements have to be taken into account. The stringent use of 3D models in the different phases of the planning process will facilitate communication and collaboration between the stake holders such as civil engineers, architects, construction managers, geological engineers, and decision makers. This keynote demonstrates that the future has already started presenting research on concepts, implementations, and experiences of collaborative multi-scale 3D city and infrastructure modelling and simulation gained by an interdisciplinary research group from Karlsruhe Institute of Technology and Technical University of Munich, Germany. Skills and methods from both, the GIS and the BIM world, are banded together to define new 3D methods. New directions are introduced to join approaches from collaborative planning and simulation, 3D multi-scale modelling, spatio-temporal geo-databases, advanced geo-services, and computer vision. The objective is to improve the digital 3D planning process of subway tracks and other infrastructures. Finally, an outlook on future research and applications is given outlining ways for BIM and GIS support in cities of the future.
