public class TLcdLonLatCircularArcByCenterPoint
extends ALcd2DEditableShape
implements ILcd2DEditableCircularArcByCenterPoint, ILcdCache
```
This class provides an implementation of ILcd2DEditableCircularArcByCenterPoint in the geodetic space. In addition to the properties defined by ILcd2DEditableCircularArcByCenterPoint, a TLcdLonLatCircularArcByCenterPoint has an ellipsoid on which it lives.
All longitude/latitude coordinates and angles are expressed in degrees. Lengths are expressed in meters.
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.
