Transform coordinates from EPSG:4326 to EPSG:31467 in Java /GWT server side
I have been using the following code from https://ariasprado.name/2012/08/13/quick-and-dirty-coordinate-transforming-using-geotools.html#comment-792 on my GWT server side and have attached all the required jars exactly as stated . Error logs attached.Any help would be greatly appreciated.Thanks in advance
import org.geotools.geometry.DirectPosition2D;
import org.geotools.referencing.CRS;
import org.opengis.referencing.crs.CoordinateReferenceSystem;
import org.opengis.referencing.operation.MathTransform;
...
CoordinateReferenceSystem sourceCrs = CRS.decode("EPSG:25829");
CoordinateReferenceSystem targetCrs = CRS.decode("EPSG:4326");
double x = (double) 636497.59434;
double y = (double) 4778964.017375;
boolean lenient = true;
MathTransform mathTransform
= CRS.findMathTransform(sourceCrs, targetCrs, lenient);
DirectPosition2D srcDirectPosition2D
= new DirectPosition2D(sourceCrs, x, y);
DirectPosition2D destDirectPosition2D
= new DirectPosition2D();
mathTransform.transform(srcDirectPostion2D, destDirectPosition2D);
double transX = destDirectPosition2D.x;
double transY = destDirectPosition2D.y;

Judging on the code, it actually looks quite allright. (I'll add a CRSCoordinateTransformer class below which definitely "works for me".)
So I would suppose a classpath problem. If you have all the required libraries? My guess would be that you have the API libraries but not the actual implementations. GeoTools provide different implementations of coordinate transformers. For instance gt2-epsg-hsql which loads transformations from an embedded HSQLDB database. Do you include one of such JARs or do you only have gt2-referencing?
Below is a snippet from mvn dependency:tree from a project where transformations are known to work:
[INFO] +- org.geotools:gt2-epsg-hsql:jar:2.4.5:compile
[INFO] | +- org.geotools:gt2-referencing:jar:2.4.5:compile
[INFO] | | +- java3d:vecmath:jar:1.3.1:compile
[INFO] | | \- org.geotools:gt2-metadata:jar:2.4.5:compile
[INFO] | | +- org.opengis:geoapi-nogenerics:jar:2.1.0:compile
[INFO] | | \- javax.units:jsr108:jar:0.01:compile
[INFO] | \- hsqldb:hsqldb:jar:1.8.0.7:compile
The version is probably old already, but this should give an idea of which libraries are required. If you use Maven, run mvn dependency:tree and check (and/or post) the output.
Now the promised CRSCoordinateTransformer class:
package org.hisrc.stopdirect.service.impl;
import org.geotools.geometry.DirectPosition2D;
import org.geotools.referencing.CRS;
import org.hisrc.stopdirect.service.CoordinateTransformer;
import org.opengis.referencing.FactoryException;
import org.opengis.referencing.crs.CoordinateReferenceSystem;
import org.opengis.referencing.operation.MathTransform;
import org.opengis.referencing.operation.TransformException;
public class CRSCoordinateTransformer implements CoordinateTransformer {
private final MathTransform forwardMathTransform;
private final MathTransform reverseMathTransform;
private final CoordinateReferenceSystem sourceCoordinateReferenceSystem;
private final CoordinateReferenceSystem targetCoordinateReferenceSystem;
public CRSCoordinateTransformer() {
try {
sourceCoordinateReferenceSystem = CRS.decode("EPSG:31468");
targetCoordinateReferenceSystem = CRS.decode("EPSG:4326");
this.forwardMathTransform = CRS.findMathTransform(sourceCoordinateReferenceSystem,
targetCoordinateReferenceSystem, true);
this.reverseMathTransform = CRS.findMathTransform(targetCoordinateReferenceSystem,
sourceCoordinateReferenceSystem, true);
} catch (FactoryException fex) {
throw new ExceptionInInitializerError(fex);
}
}
@Override
public double[] lonLatToXY(double lon, double lat) throws TransformException {
DirectPosition2D srcDirectPosition2D = new DirectPosition2D(sourceCoordinateReferenceSystem, lat, lon);
DirectPosition2D destDirectPosition2D = new DirectPosition2D();
try {
reverseMathTransform.transform(srcDirectPosition2D, destDirectPosition2D);
return new double[] { destDirectPosition2D.y, destDirectPosition2D.x };
} catch (Error error) {
throw error;
}
}
@Override
public double[] xyToLonLat(double x, double y) throws TransformException {
DirectPosition2D srcDirectPosition2D = new DirectPosition2D(sourceCoordinateReferenceSystem, y, x);
DirectPosition2D destDirectPosition2D = new DirectPosition2D();
forwardMathTransform.transform(srcDirectPosition2D, destDirectPosition2D);
return new double[] { destDirectPosition2D.y, destDirectPosition2D.x };
}
}
