name: Name by which the coordinate reference system is identified.
description: Informal description of this coordinate reference system.
geodeticDatum: Name by which this datum is identified.
verticalDatum: Name by which the vertical datum is identified.
mapProjection: Name by which the map projection is identified.
mapZone: Name by which the map zone, relating to the MapProjection, is identified.
eastings: Location along the easting of the coordinate system of the target map coordinate reference system.
northings: Location along the northing of the coordinate system of the target map coordinate reference system.
orthogonalHeight: Orthogonal height relative to the vertical datum specified.
xAxisAbscissa: Value along the easting axis of the end point of a vector indicating the position of the local x axis of the engineering coordinate reference system.
xAxisOrdinate: Value along the northing axis of the end point of a vector indicating the position of the local x axis of the engineering coordinate reference system.
scale: Scale to be used, when the units of the CRS are not identical to the units of the engineering coordinate system.

Remarks

This structure is a member of API_GeoLocation. These Geo Referencing map parameters correspond to the IfcCoordinateReferenceSystem and IfcMapConversion entities of the IFC standard.
