hello there, apologies if i've posted this several times today, i seem to have some problems with nabble.
I'm very much a geoserver/openlayers newbie but i've cobbled together a basic map showing blue marble imagery of the antartic region. The problem i have can be best described by the attached image - a radial section from the pole is not being displayed followed by a rectangluar section on the right hand side. The radial chunk missing i would have thought relates to the extent of my coverage stored in geoserver but it looks good - -180 to 180 on X and -48 to -90 on Y. I have no idea what would be causing the straight rectangular gap in the image. Image here: http://img220.imageshack.us/img220/5153/wmssb9.png I would appreciate any pointers to fixing this. As i say, i've only been using geoserver and openlayers for a day now. Before then i was happily doing unprojected google map code so this is my first WMS trial. WMS is in EPSG:4030 but openlayers is projecting in EPSG:3031. I've used the bounds as described by nsdic.org: -12400000,-12400000, 12400000,12400000. Here is the native SRS WKT from geoserver, if relevant: * Native Spatial Reference System for Coverage: Generate Envelope after setting the property. Native SRS WKT: GEOGCS["Unknown datum based upon the WGS 84 ellipsoid", DATUM["Not specified (based on WGS 84 ellipsoid)", SPHEROID["WGS 84", 6378137.0, 298.257223563, AUTHORITY["EPSG","7030"]], AUTHORITY["EPSG","6030"]], PRIMEM["Greenwich", 0.0, AUTHORITY["EPSG","8901"]], UNIT["degree", 0.017453292519943295], AXIS["Geodetic longitude", EAST], AXIS["Geodetic latitude", NORTH], AUTHORITY["EPSG","4030"]] My Openlayers script; <script src="http://localhost:8081/geoserver/openlayers/OpenLayers.js"; type="text/javascript"> </script> <script defer="defer" type="text/javascript"> var map; var untiled; var tiled; function setHTML(response) { document.getElementById('nodelist').innerHTML = response.responseText; }; OpenLayers.IMAGE_RELOAD_ATTEMPTS = 5; OpenLayers.DOTS_PER_INCH = 25.4 / 0.28; function init(){ var bounds = new OpenLayers.Bounds( -12400000,-12400000, 12400000,12400000 ); var options = { controls: [], maxExtent: bounds, maxResolution: 25000, projection: "EPSG:3031", //WGS 84 / Antarctic Polar Stereographic units: 'meters' }; map = new OpenLayers.Map('map', options); // setup tiled layer tiled = new OpenLayers.Layer.WMS( "QQ:Antarctica_Image - Tiled", "http://localhost:8081/geoserver/wms";, { width: '800', styles: '', height: '800', layers: 'QQ:Antarctica_Image', srs: 'EPSG:4030', format: 'image/png', tiled: 'true', tilesOrigin : "-180,-90" }, {buffer: 0} ); // setup single tiled layer untiled = new OpenLayers.Layer.WMS( "QQ:Antarctica_Image - Untiled", "http://localhost:8081/geoserver/wms";, { width: '800', styles: '', height: '800', layers: 'QQ:Antarctica_Image', srs: 'EPSG:4030', format: 'image/png' }, {singleTile: true, ratio: 1} ); map.addLayers([untiled, tiled]); // setup controls and initial zooms map.addControl(new OpenLayers.Control.PanZoomBar()); map.addControl(new OpenLayers.Control.Navigation()); map.addControl(new OpenLayers.Control.Scale($('scale'))); map.addControl(new OpenLayers.Control.MousePosition({element: $('location')})); map.addControl(new OpenLayers.Control.LayerSwitcher()); //map.addControl(new OpenLayers.Control.OverviewMap()); map.zoomToExtent(bounds); // support GetFeatureInfo map.events.register('click', map, function (e) { document.getElementById('nodelist').innerHTML = "Loading... please wait..."; var url = map.layers[0].getFullRequestString( { request: "GetFeatureInfo", EXCEPTIONS: "application/vnd.ogc.se_xml", BBOX: map.getExtent().toBBOX(), X: e.xy.x, Y: e.xy.y, INFO_FORMAT: 'text/html', QUERY_LAYERS: map.layers[0].params.LAYERS, FEATURE_COUNT: 50, WIDTH: map.size.w, HEIGHT: map.size.h }, "http://localhost:8081/geoserver/wms"; ); OpenLayers.loadURL(url, '', this, setHTML, setHTML); OpenLayers.Event.stop(e); }); } </script> _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users
