I have got 2 layer groups(group A and B): The Group A(the overlayer) can match to the Google Sattelite Map(the Baselayer) perfectly,but when I change the Group B as the overlayers to the Google Sattelite Map,it just work like that: http://geekjack.hostesr.com/bate.png (The blue surface and the yellow line are parts of Group B) .What I want to say is how can I align the Group B(the overlayer) to the Google Sattelite Map(the Baselayer) to Eliminate the bias and make it work well. Part of my codes:
function init(){ var options = { projection: new OpenLayers.Projection("EPSG:900913"), displayProjection: new OpenLayers.Projection("EPSG:4326"), units: "m", maxResolution: 156543.0339, maxExtent: new OpenLayers.Bounds(-20037508.34, -20037508.34, 20037508.34, 20037508.34) }; map = new OpenLayers.Map('map', options); var gmap = new OpenLayers.Layer.Google( "Google Sattelite", {type: G_SATELLITE_MAP, 'sphericalMercator': true} ); var test = new OpenLayers.Layer.WMS( "TOPP GroupB", "http://localhost:8080/geoserver/wms?", { layers: 'Group_B', styles: '', srs: 'EPSG:4326', format: 'image/png', tiled: 'true', // tilesOrigin : "-60,-28", transparent:false }, { 'opacity': 0.2, 'isBaseLayer': true, 'wrapDateLine': true } ); map.addLayers([gmap,test]); } By the way,i want to know:Does the "tilesorigin" work right in geoserver 2.0.2,it seems no changes when i use it in geoserver 2.0 bu it works in geoserver 1.7.5.(my English is pool ,maybe i cannot discribe the problem clearly,but i really need your help),thank you all! -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/A-problem-about-overlayers-tp5366694p5366694.html Sent from the OpenLayers Users mailing list archive at Nabble.com. _______________________________________________ Users mailing list Users@openlayers.org http://openlayers.org/mailman/listinfo/users
