GeoLocationData - TransformFromLonLatAlt() & TransformToLonLatAlt()

When using GeoLocationData object - Has CS-MAP been used as AutoCAD does?, If so, where does BricsCAD keep the dictionaries?

Are this methods working or are they dummies:
public Point3d TransformFromLonLatAlt(Point3d geoPt);
public Point3d TransformToLonLatAlt(Point3d dwgPt);

Thanks,
