Hi Thom,
The following code is the basis of some working code that should get you
started.
Brett
import org.geotools.geometry.jts.JTS;
import org.geotools.referencing.CRS;
try {
// Create a transform from Web Mercator (WGS84) to GDA 94 MGA Zone 55
transform = CRS.findMathTransform( /* from */ CRS.decode("EPSG:3857"), /*
to */ CRS.decode("EPSG:28355"));
}
catch (FactoryException e) {
e.printStackTrace();
}
newPoint = (Point) JTS.transform(oldPoint, transform);

Subject: [Geotools-gt2-users] Need a coordinate conversion example
Hi,
I'm looking for a simple java example which converts a map coordinate (say,
38.8895° N, 77.0352° W, 575ft) to another coordinate system (geocentric, UTM,
or MGRS). Is such a thing possible with GeoTools? The CRS tutorial seems to
rely on the map frame display to mediate the conversion, but I don't want the
overhead of displaying the point on a map. I just need the numbers.
Thanks!
