GeoBIM - Phase 1

"GeoBIM - Phase 1", Jantien Stoter and Claire Ellul

In both the Geographic Information (Geo) and Building Information Modelling (BIM) domains, it is widely acknowledged that the integration of data from both domains is beneficial and a crucial step forwards for future 3D city modelling, as well as for facing the multi-disciplinary challenges of our built environment. From the data perspective, this integration handles about the question how to integrate design & construction data from the BIM domain and geospatial data (both 2D and 3D).

There are currently many different interpretations and methods to convert BIM data into geo data and vice versa and they all have pros and cons. For a fundamental solution supporting the life-cycle of objects, we need one uniform and standardised transformation based on a common view on how individual, highly detailed BIM-models can be best integrated in geo-databases that contain topographic data at lower levels of detail. This integration question asks for a cross-country and cross-organisational approach, which is the topic of a new EuroSDR project.

The general aim of the project is to detail both the needs and the issues of Geo-BIM integration, studied from use cases as well as from existing experiences in the participating countries.
