Geodetic datum used by this projection, defining the ellipsoid model and coordinate reference frame.

// Java
public TGIS_CSDatum getDatum();
 
public void setDatum(
  TGIS_CSDatum _value
);

// Oxygene
public
  property Datum : TGIS_CSDatum read write;

PURPOSE: Store and change the datum used for coordinate system transformations.

BEHAVIOR: Setting this property updates both Datum and Ellipsoid state and calls datumChanged to let subclasses recalculate dependent values.

CONSTRAINTS: The datum must be valid. Changing it may invalidate cached projection math.
