Automating data flow between GIS and BIM

December 19th, 2017, Published in Articles: EE Publishers, Articles: PositionIT

Phase 2 of the Open Geospatial Consortium’s (OGC) Future City Pilot aims to improve the automation of the flow of data between geospatial systems (GIS) and building information models (BIM) systems, as well as address a number of related interoperability challenges.

The OGC is seeking interested sponsors to define the challenges for Phase 2 of the project.

Completed in 2017, the Future City Pilot, Phase 1 (FCP1) demonstrated that interoperability between CityGML and BIM Industry Foundation Classes (IFC) works well in practice, and showed clear benefits in use cases for urban planning, social care and flood modelling. However, a significant amount of manual intervention needed to be employed.

Phase 2 of the Future City Pilot (FCP2) aims to improve the automation of the flow of data, as well as address a number of related interoperability challenges, including:

  • Comparing data conversion with data linking approaches;
  • Looking at tools that consume both CityGML and BIM structured data;
  • Data structures that support the integration of GIS data and BIM data;
  • Linking real-time sensor information with 3D City Models encoded as CityGML;
  • Security models to protect the sensor readings, including Single-Sign On (SSO) methodologies to protect parts of the 3D City Model;
  • Understanding where and how to capture location and time information: the ability to correlate location in different coordinate reference systems (CRS) such as local, regional, global, and understand if and how the integrity of the location data has changed through that process (Survey4BIM use case);
  • Data linking to facilitate asset management over dispersed geographies.

The Engineering Reports documenting the outcomes of FCP1 are available at The scope of the second phase of this pilot as currently planned will include the demonstration of a common architecture and data model in multiple cities. The number of cities used for the demonstration will depend upon the sponsor requirements.

Organisations interested in participating can contact Bart De Lathouwer, director of the OGC’s Innovation Program.
