This IFC4 data sample provides a technical implementation reference for geographic referencing using IfcMapConversion and IfcProjectedCRS. This technical resource serves as an official demonstration of the IFC4 geographic referencing schema. It provides a structured example of how to correctly implement coordinate reference systems within an openBIM environment. The dataset specifically focuses on the application of IfcMapConversion and IfcProjectedCRS entities, which are essential for aligning BIM models with real-world geospatial data. By examining the underlying structure, users can understand the precise syntax required to map local project coordinates to global geographic systems, ensuring interoperability between architectural models and wider GIS infrastructure projects.

The download is a single file containing .IFC files.

Professionals can utilise this data to validate their own IFC export settings or to study the schema requirements for georeferencing. It acts as a reference for software developers and BIM managers configuring coordinate systems in authoring tools. By importing this file into a BIM viewer or IFC-compliant software, users can inspect the entity hierarchies and parameters to ensure their own models are correctly aligned with project-specific geographic requirements during the data exchange process.

This asset is primarily intended for BIM managers, computational designers, and software engineers working on large-scale infrastructure or complex site-based projects. It is essential for teams needing to bridge the gap between architectural design and urban planning software. Professionals searching for coordinate system setup, IFC schema compliance, or geospatial data integration will find this sample invaluable for standardising workflows across different platforms and ensuring that all project data is accurately positioned within a global or local coordinate framework.
