TLcdLonLatHeightMPolygon
ILcd3DEditablePolygon
in the geodetic space.
This class is thread-safe for concurrent read-only access of its contents. For read-write access, external locking must be used. Such locking is typically done at the model level.
Note that the ILcd3DEditablePointList representing the actual geometry should provide geodetic points (TLcdLonLatHeightPoint), not cartesian (TLcdXYZPoint).
