Hi all,
I have try to transform coordinate from (x,y) to (lat,long) system. I have
read some posts on this list and the wiki (Coordinate Transformation
Services for Geotools 2.0) but I haven't understand how to do it. I extract
my source CRS from a GridCoverage2D, and I would transform the bottom-left
corner coordinates in (lat, long). I have try with this code:
// pitGC is a GridCoverage2D
CoordinateReferenceSystem sourceCRS =
pitGC.getCoordinateReferenceSystem();
CoordinateReferenceSystem targetCRS =
DefaultGeographicCRS.WGS84;
MathTransform transform = CRS.findMathTransform(sourceCRS,
targetCRS);
//where srcPoint is the coordinate of the bottom-left coorner of
the grid
Coordinate source =new Coordinate(srcPts[0],srcPts[1]);
GeometryFactory gnFactory=
JTSFactoryFinder.getGeometryFactory(null);
Point sourcePoint = gnFactory.createPoint(source);
Geometry target = JTS.transform(sourcePint,transform);
but the target object have the same value of the sourcePoint. Maybe my
targetCRS is wrong?
thanks and regards
