Hello,
I am having some troube trying to define a CARTESIAN_2D crs in a udig map, and
I would really appreaciate any idea about what I could be doing wrong
I am building a mapviewer which has a JPG image as base layer (which is not
really georeferenced, but I added a worldfile to georeference it by using its
pixels), and over it I have some overlays layers coming from mapserver with
polygons and points, like for example POINT (282.4230769230767
-876.2142857142861) . This works if I deal with the map and the layers as they
were WGS84 :)
layer.setCRS(DefaultGeographicCRS.WGS84);
The problem about this workaround is that if use WGS84, when I try to filter
the layer by bbox, I have seen that only features which intersect with
(-180,180, -90,90) are returned, those who are out of (-180,180, -90,90) are
never returned, as if they dont exist...
ReferencedEnvelope bbox = new ReferencedEnvelope(new Envelope
(40, 60, 40 ,60),DefaultGeographicCRS.WGS84);
FeatureSource<SimpleFeatureType, SimpleFeature> source =
layer.getResource( FeatureSource.class, null );
FilterFactory2 ff = (FilterFactory2)
CommonFactoryFinder.getFilterFactory(GeoTools.getDefaultHints());
Geometry geom = new GeometryFactory().toGeometry(bbox);
Intersects bboxFilter =
ff.intersects(ff.property("msGeometry"), ff.literal(geom));
FeatureCollection<SimpleFeatureType, SimpleFeature> results;
So now I am trying to define the map with a CARTESIAN_2D crs, and layers :
map = (Map) ProjectFactory.eINSTANCE.createMap();
map.getViewportModelInternal().setCRS(DefaultEngineeringCRS.CARTESIAN_2D);
.....
.....
layer.setCRS(DefaultEngineeringCRS.CARTESIAN_2D);
But then, the wfs layers coming from mapserver are not rendered and this
message appears in the log:

Why would udig want to transform anything to WGS 84? I guess I have not defined
the crs correctly, right?
If you have any idea, I would really appreciate it
Thank you very much :)
