Domain:

crmgeo:SP4 Spatial Coordinate Reference System

Range:

crm:E26 Physical Feature

Quantification:

1,1:1,n

Scope note:

This property defines the physical reference features that ground a spatial coordinate reference system in the real world. In surveying and geodesy this is part of the datum definition and is often a point identified by a physical feature on earth (sometimes monuments) where the earth approximation ellipsoid touches the earth and one axis of the ellipsoid runs through.
