As part of their Integrated Digital Built Environment (IDBE) joint working group, the Open Geospatial Consortium (OGC) and BuildingSmart International (BSI) have published “Built environment data standards and their integration: an analysis of IFC, CityGML and LandInfra”.
The paper looks at a variety of challenges and addresses the need to develop and coordinate better integration at a high level between BIM and GIS standards. It focuses on four key topics:
- Predominant disparities that hinder integration
- Fundamental operations that underpin use cases
- Methods of integration in usage
- Proposed action points
The IDBE working group will continue to work on the points highlighted and aims to overcome integration challenges, to articulate the main use cases, devise a system of common unique identifiers and agree on a collaborative harmonisation approach.
This paper – which is free to download from the OCG’s website – is currently out for endorsement by the Standard Committee at buildingSMART to become a formal Technical Report.
