Hey,
The programm is:
-------------
import org.geotools.referencing.CRS;
import org.opengis.referencing.FactoryException;
import org.opengis.referencing.crs.CoordinateReferenceSystem;
public class Test {
public static void main(String[] args) {
Test test = new Test();
test.run();
}
public void run() {
try {
CoordinateReferenceSystem crs = CRS.decode("EPSG:4326");
if (CRS.getProjectedCRS(crs).equals(null)) {
System.out.println("Spherical");
} else {
System.out.println("Cartographic");
}
} catch (FactoryException e) {
System.out.println("CRS Decode went wrong: " +
e.getMessage());
}
}
}
-------------
Regards,
Jochen
