Re: [Geotools-gt2-users] Transformation between CH1903/LV03 and WGS84

[<tzu...@da...>]

Bonjour Martin

Once more thank you. So I tested your changes.

I checkout the revision 24581 and compiled gt2-epsg-hsql-xxx.jar and
gt2-referencing-xxx.jar with maven. Now I get a new exception
(UnsupportedImplementationException) at line 33. I don't know why because
EPSG:21781 is a official EPSG code for CH1903/LV03. Again my JUnit test 
http://www.nabble.com/file/6781/GeoToolsTest.java GeoToolsTest.java . 

The axis order of CH1903/LV03 is y, x (east, north). In this reference
system is y=x and x=y. This can be a little confused. 

I try to find out if there an invalid calculation in the gt classes or if
there a invalid wkt string. But my knowledge in this field is poor. I hope
you can help me?

Thank you.
Regards, Thomas
