Hi again,
I guess I found the solution for my Problem, on
http://www.epsg-registry.org/ I found for UTM zone 32N the code EPSG:32632,
which produces the same results as the transformation on the cited website
in the original post.
Furthermore I mixed up lon and lat in my example code.
Thanks anyway,
Stefan

Betreff: [Geotools-gt2-users] (Newbie) transform WGS84 (lat/lon) to UTM32
Hi,
I'm new to GeoTools, therefore my question might be quiet simple.
What I want to do is to transform a coordinate from WGS84 to UTM32.
Based on the UserGuide found on
http://docs.codehaus.org/display/GEOTDOC/03+How+to+Transform+a+Geometry I
have the following code:
CoordinateReferenceSystem sourceCRS = CRS.decode("EPSG:4326");
CoordinateReferenceSystem targetCRS = CRS.decode("EPSG:23032");
MathTransform transform = CRS.findMathTransform(sourceCRS, targetCRS);
GeometryFactory geometryFactory = JTSFactoryFinder
.getGeometryFactory(null);
Point p = geometryFactory.createPoint(new Coordinate(6,49));
Geometry tp = JTS.transform(p, transform);
System.out.println(tp.toString());
The output is: POINT (5328456.906858956 865342.1771206289)
According to http://home.hiwaay.net/~taylorc/toolbox/geography/geoutm.html
the UTM-Point should be somewhere at (280586 5431792) zone32 hemisphere N
I guess my major Problem is that I don't know where I can find the proper
codes for the parameter in CRS.decode(String code). Even the javadoc at
http://javadoc.geotools.fr/snapshot/org/geotools/referencing/CRS.html#decode
(java.lang.String) didn't help me.
Is at least the basic approach right or is there a totally different
solution for transforming?
Thanks in advance for any help
Stefan
