[Geotools-gt2-users] Note: Regard AXIS when creating an WKT

[Erich S. <eri...@gm...>]

Hello all,

thanks again for all the helpful mails you wrote.

Meanwhile my application is nearly complete.
When (junit-)testing it, I again got switched values after transforming a
coordinate from WGS84 to Gauss-Kruger.
But this only happend, when I use crsFactory.createFromWKT( <wktGK> ) instead of
CRS.decode( "EPSG:31466" ).
So I investigated the WKT string and detected, that if the axises are ordered as
in EPSG (lat, lon), you have to build an WKT string like this:

...
 UNIT["m", 1.0],
 AXIS["Northing", NORTH],
 AXIS["Easting", EAST],
 AUTHORITY["EPSG","31466"]]
...

but when the axis ordering is (lon, lat) you also have to consider that:

...
 UNIT["m", 1.0],
 AXIS["Easting", EAST],
 AXIS["Northing", NORTH],
 AUTHORITY["EPSG","31466"]]
...

to get the results at the expected places: Coordinate.x / Coordinate.y .

Yes, I believe, this is yesterday's news to the cracks among you, but I was a 
bit surprised and so could other newbies, too. Therefore I wrote this short note
;-)

Cheers
Erich
