Hello,
thanks for your reply.
I don't think that extent can be specified in wkt, at least I did not find a
way to do it.
I managed to specify the extent like below:
public static CoordinateReferenceSystem getDefaultCRS() throws
FactoryException{
if (defaultCRS != null){
return defaultCRS;
}
Map<String,Object> properties = new HashMap<String,Object>(4);
properties.put(NAME_KEY, "WGS84(DD)(0..360,-90..90)");
ExtentImpl extent = new ExtentImpl();
Collection<GeographicExtent> col = new
ArrayList<GeographicExtent>();
col.add(new GeographicBoundingBoxImpl(0,360, -90, 90));
extent.setGeographicElements(col);
properties.put(DOMAIN_OF_VALIDITY_KEY, extent);
defaultCRS = new DefaultGeographicCRS(properties,
DefaultGeodeticDatum.WGS84,
DefaultEllipsoidalCS.GEODETIC_2D);
return defaultCRS;
}
public static void main(String[] args) throws IOException,
FactoryException {
System.out.println(DefaultGeographicCRS.WGS84.getDomainOfValidity());
System.out.println(DefaultGeographicCRS.WGS84.toWKT());
System.out.println(getDefaultCRS().getDomainOfValidity());
}
But now how to connect this crs with WGS84 and other default coordinates, in
order to seamlessly use JTS.transform() ?
thank you

The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE:
Pinpoint memory and threading errors before they happen.
Find and fix more than 250 security defects in the development cycle.
Locate bottlenecks in serial and parallel code that limit performance.
