Returns the transformation used to convert ASTERIX coordinates to WGS_84 lon/lat
coordinates. The source and destination references must be set to the
return by the implementation
of this method.
The source reference of the returned
should be the reference representing the ASTERIX coordinate system. This can
be different per category:
|1||Grid coordinates relative to the radar|
|30||Grid coordinates relative to the radar|
|48||Grid coordinates relative to the radar|
|62||Grid coordinates relative to the radar|
Please refer to the asterix specifications for details about the used
coordinate systems (www.eurocontrol.int/asterix).
Note that in a future version new categories might be added that use a
different coordinate system.
The destination reference of the provided
should be WGS 84, e.g.
new TLcdGeodeticReference( new TLcdGeodeticDatum() )
This method should perform very fast, as it is invoked frequently.
