Re: [Geotools-gt2-users] convert wgs84 coordinate to Google Map coordinate system(EPSG 3785) with geotools and java

[Oleksandr H. <guz...@gm...>]

Hey Dmitry,

here is the small example I wrote for you, though I am not sure if CRS code
you gave corresponds to UTM 12N ( please see this site for the codes
http://www.epsg-registry.org/ ).

import com.vividsolutions.jts.geom.Coordinate;
import com.vividsolutions.jts.geom.GeometryFactory;
import com.vividsolutions.jts.geom.Point;
import org.geotools.geometry.jts.JTS;
import org.geotools.referencing.CRS;
import org.geotools.referencing.crs.DefaultGeographicCRS;
import org.opengis.referencing.FactoryException;
import org.opengis.referencing.crs.CoordinateReferenceSystem;
import org.opengis.referencing.operation.MathTransform;
import org.opengis.referencing.operation.TransformException;

/**
 * User: san
 * Date: 23/06/12
 * Time: 6:09 PM
 */
public class TestReproject {


    public static void main(String[] args) throws FactoryException,
TransformException {
        GeometryFactory gf = new GeometryFactory();
        Coordinate c = new Coordinate(175784.99999999997, 5842215.0);

        Point p = gf.createPoint(c);

        CoordinateReferenceSystem utmCrs = CRS.decode("EPSG:3785");
        MathTransform mathTransform = CRS.findMathTransform(utmCrs,
DefaultGeographicCRS.WGS84, false);
        Point p1 = (Point) JTS.transform(p, mathTransform);

        System.out.println(p1.getCoordinate());

    }
}

Cheers
