Actually google maps are cut on +-85.0511287798066 degrees of latitude.
countries900913.png looks accurate like Google.
I used same WKT as I found in geoserver's help
(http://localhost:8080/geoserver/srsHelp.do)
But StreamingRenderer does not seem to render in '900913' google
projection . My image looks like your second screenshot with 4326
projection.
What am I doing wrong?
I use code given below. In simplified form it is quite short.
===========================CODE===========================
public static void main(String[] args) throws Throwable {
//.... skipped JFrame initialization
//.... skipped data loading code
MapContext map = new DefaultMapContext(getCRS());
//....skipped styles creation and adding layers to context:
map.addLayer(<<--features-->>, <<--style-->>);
StreamingRenderer renderer = new StreamingRenderer();
renderer.setContext(map);
renderer.paint((Graphics2D) p.getGraphics(), new Rectangle(0, 0,
256, 256), new ReferencedEnvelope(new Envelope(0, 180, 0,
85.0511287798066), getCRS()));
}
public static CoordinateReferenceSystem getCRS() throws Throwable {
String wkt1 = "<<--Skipped WKT of 900913 projection you can
find it in my previous post-->>";
return CRS.parseWKT(wkt1);
}
===========================/CODE===========================
What should I change to reproject properly?
