Is there any example of code with transform from one system to other
with the new API ?
Make sure that the following JAR appears in the class-path:
geoapi.jar; gt2-referencing.jar; gt2-epsg-hsql.jar; hsqldb.jar; vecmath.jar
Note: if all JARs are in the same directory and if you use the JAR from
the Maven 2 build (e.g. the *2.2-RC0.jar file), then the following
should be enough:
java -classpath gt2-epsg-hsql.jar ...
All other dependencies are specified in the META-INF file provided with
each gt2-*-2.2-RC0.jar file.
import org.opengis.referencing.*;
import org.opengis.referencing.crs.*;
import org.opengis.referencing.operation.*;
import org.geotools.referencing.FactoryFinder;
CRSAuthorityFactory crsFactory =
FactoryFinder.getCRSAuthorityFactory("EPSG", null);
CoordinateReferenceSystem sourceCRS =
crsFactory.createCoordinateReferenceSystem("EPSG:4326");
CoordinateReferenceSystem targetCRS =
crsFactory.createCoordinateReferenceSystem("EPSG:put-lambert-II-code-here");
CoordinateOperationFactory opFactory =
FactoryFinder.getCoordinateOperationFactory(null);
CoordinateOperation operation =
opFactory.createCoordinateOperation(sourceCRS, targetCRS);
MathTransform mt = operation.getMathTransform();
DirectPosition sourcePt = new GeneralDirectPosition(...);
DirectPosition targetPt = mt.transform(sourcePt, null);
