Hi, the code is:
private void test3() throws FactoryException, MismatchedDimensionException,
TransformException {
CoordinateOperationFactory coFactory =
FactoryFinder.getCoordinateOperationFactory(null);
String codeutm = "EPSG:23030";
String codegeo = "EPSG:4154";
CoordinateReferenceSystem crs = null;
CRSAuthorityFactory af = FactoryFinder.getCRSAuthorityFactory("EPSG",
null);
CoordinateReferenceSystem sourceCRS =
af.createCoordinateReferenceSystem(codegeo);
CoordinateReferenceSystem targetCRS =
af.createCoordinateReferenceSystem(codeutm);
CoordinateOperation op = coFactory.createOperation(sourceCRS,
targetCRS);
MathTransform trans = op.getMathTransform();
System.out.println("Math Transform: " + trans.toWKT());
// transform some points
DirectPosition pt = new GeneralDirectPosition(39.54756533333333,
-3.5980695277777763);
System.out.println("Input point: " + pt);
pt = trans.transform(pt, null);
System.out.println("Output point: " + pt);
}
the jars with epsg are:
gt2-epsg-access-2.2-RC3.jar
gt2-epsg-hsql-2.2-RC3.jar
gt2-epsg-postgresql-2.2-RC3.jar
gt2-epsg-wkt-2.2-RC3.jar
into the las jar are the EPSG datum for EPSG:23030 and EPSG 4154
are corrects.
The parametes for center of Spain are:
Ax = 131.0320
Ay = 100.2510
Az = 163.3540
Rx = -1,2438
Ry = -0.0195
Rz = -1.1436
scale= -9.3900
but I have a coorect calc with geotrans soft with the next params:
-89.5000058332924 -93.8000088918721 -123.099998474121 0.00 0.00
-0.000000756309358135336 0.0000012000000791
