Gaby,
I recommend *not* using this property because it will make everything
use this order, and will break lat/lon GeoTools code in the same VM
(your raster reprojections?). I wrote the same userguide link in the
original draft of my email, then removed it when I realised that it is
the *wrong* thing to do. The only people who should be using this link
are those with urgent backwards compatibility concerns. Everyone else
should not use this property; CRS.decode will ignore this property for
OGC URN and OGC HTTP URI CRS identifiers. Try these with and without
this property:
System.out.println(CRS.decode("urn:ogc:def:crs:EPSG:2193"));
System.out.println(CRS.decode("http://www.opengis.net/def/crs/EPSG/0/2193";));
The underlying concept is that NZTM is registered with EPSG as PROJCS
with Northing/Easting axis order. *Doh.* But that is the way it is.
For NZTM2000, x = North and y = East, and you should continue to use
your original:
ReferencedEnvelope envelope = new ReferencedEnvelope(xmin, xmax, miny, maxy,
sourceCRS);
Kind regards,
Ben.
