Dear All,
I would like to ask you if any of you have successfully done a ED50
datum to ETRS89 datum reprojection (or viceversa), using a NTv2
format grid file.
I am using the next code:
double[] srcPts = {lat,lon};
double[] dstPts = new double[2];
CRSAuthorityFactory fact;
fact = ReferencingFactoryFinder.getCRSAuthorityFactory("epsg",
null);
CoordinateReferenceSystem sourceCRS;
CoordinateReferenceSystem targetCRS;
String foundTransf = null;
sourceCRS = fact.createCoordinateReferenceSystem("4258");
targetCRS = fact.createCoordinateReferenceSystem("23030");
MathTransform mt = CRS.findMathTransform(sourceCRS, targetCRS);
foundTransf = mt.toWKT();
mt.transform(srcPts, 0, dstPts, 0, 1);
I have place the grid in the classpath renamed to "sped2et.gsb", but
for some reason findMathTransform() does not find it.
I am using Geotools 8.0.RC1 version.
Thank you in advance
