Overview - ISO/TR 23262:2021 (GIS / BIM interoperability)
ISO/TR 23262:2021 is a Technical Report that investigates barriers and proposes measures to improve interoperability between the geospatial (GIS) and building information modelling (BIM) domains. Prepared by ISO/TC 59/SC 13 with reference to ISO/TC 211 work, the report maps conceptual and technological gaps at the data, service and process levels (using the enterprise interoperability framework from ISO 11354). It does not set mandatory rules but identifies issues, opportunities and future topics for standardization to align ISO GIS standards with BIM standards.
Key topics and technical focus
The report highlights technical topics and potential requirements to enable seamless GIS–BIM integration:
- Interoperability levels: comprehensive review of data-level, service-level, and process-level interoperability challenges.
- Conceptual models and application schemas: alignment of conceptual schemas, schema languages (e.g., UML/EXPRESS), and application schema design patterns across GIS and BIM.
- Data templates and IFC: discussion of IFC-related data templates and how BIM data can map to geospatial schemas.
- Georeferencing and spatial representation: treatment of coordinate reference systems, positioning and consistent spatial models for GIS/BIM exchanges.
- Handling of construction objects (product handling): managing product descriptions and lifecycle information across domains.
- Service interoperation: GIS-to-BIM and BIM-to-GIS service flows, APIs and information exchange patterns.
- Standards alignment & gaps: identification of revision needs in ISO/TC 211 and ISO/TC 59/SC 13 standards and consideration of work from buildingSMART (bSI), OGC, and CEN.
- Recommendations and future work: proposals such as linking abstract concepts, creating a geospatial–BIM dictionary, and developing information exchange guidelines.
Practical applications and who uses it
ISO/TR 23262 is targeted at professionals and organizations working at the intersection of geospatial and built‑asset information:
- Standards bodies and technical committees (ISO/TC 211, ISO/TC 59/SC 13)
- GIS and BIM software vendors implementing interoperable data models and services
- AECO professionals (architecture, engineering, construction, operations) integrating urban context with asset models
- Asset managers, surveyors and infrastructure owners aiming for integrated lifecycle data
- Smart city and digital twin initiatives seeking consistent geospatial + BIM data flows
Use cases include integrated asset lifecycle management, planning/urban analytics, construction coordination, and cross-domain data exchange between mapping and building models.
Related standards and next steps
Relevant references and contexts include ISO 11354 (enterprise interoperability framework), ISO 19100 series (ISO/TC 211), ISO 16739 / IFC and ISO 19650 (BIM information management). The report’s annexes (IFC/data templates, georeferencing, spatial representation) provide focused guidance and point to priority areas for standardization and implementation.
