Hi, I'm sorry, it was not a crs problema. I have just limited the extent of the layers in mapserver to (-180,180, -90,90)
Thanks Joaquín -----Mensaje original----- De: Joaquín Rodriguez-Guerra Urcelay Enviado el: martes, 25 de octubre de 2011 16:33 Para: [email protected] Asunto: [udig-devel] Create Map with CARTESIAN_2D 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: net.refractions.udig.project.render.RenderException: Problem rendering: Error transforming bbox at net.refractions.udig.render.internal.feature.basic.BasicFeatureRenderer.render(BasicFeatureRenderer.java:388) at net.refractions.udig.render.internal.feature.basic.BasicFeatureRenderer.render(BasicFeatureRenderer.java:222) at net.refractions.udig.project.internal.render.impl.RenderJob.startRendering(RenderJob.java:108) at net.refractions.udig.project.internal.render.impl.RenderJob.run(RenderJob.java:213) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) Caused by: java.lang.Exception: Error transforming bbox at org.geotools.renderer.lite.StreamingRenderer.getLayerQuery(StreamingRenderer.java:992) at org.geotools.renderer.lite.StreamingRenderer.processStylers(StreamingRenderer.java:1916) at org.geotools.renderer.lite.StreamingRenderer.paint(StreamingRenderer.java:773) at org.geotools.renderer.lite.StreamingRenderer.paint(StreamingRenderer.java:581) at net.refractions.udig.render.internal.feature.basic.BasicFeatureRenderer.render(BasicFeatureRenderer.java:359) ... 4 more Caused by: org.opengis.referencing.operation.OperationNotFoundException: No transformation available from system "EngineeringCRS[Cartesian 2D]" to "GeographicCRS[WGS 84]". at org.geotools.referencing.operation.DefaultCoordinateOperationFactory.createOperation(DefaultCoordinateOperationFactory.java:387) at org.geotools.referencing.operation.BufferedCoordinateOperationFactory.createOperation(BufferedCoordinateOperationFactory.java:254) at org.geotools.geometry.jts.ReferencedEnvelope.transform(ReferencedEnvelope.java:629) at org.geotools.renderer.lite.StreamingRenderer.getLayerQuery(StreamingRenderer.java:975) ... 8 more Why would udig want to transform anything to WGS 84? I guess I have not defined the crs correctly, right?
