Figure 282 — Project Global Positioning
Adding a geospatial coordinate reference to the geometric representation context using a recognized coordinate reference system (CRS). This allows to position the project coordinate system on Earth (normally using eastings, northings, elevation above horizontal and vertical datums, and orientation).
HISTORY New concept template enabled by schema enhancements in IFC4.
