Hi List, I'm trying to overlay a google map with data from postgis database (roads). On larger scale things seem to be ok, but when zoomed in at 'meters' scale, roads do not match: http://www.duif.net/900913-mismatch.jpg
Question: has somebody experienced this? Or does somebody have an example of perfect matching of two layers? When I look at the multimap mercator example: http://www.openlayers.org/dev/examples/multimap-mercator.html zooming in at for example Amsterdam, The Netherlands, I see about the same mismatch?? my code: var options = { projection: "EPSG:900913", units: "m", maxResolution: 156543.0339, maxExtent: new OpenLayers.Bounds(-20037508, -20037508, 20037508, 20037508.34) }; map = new OpenLayers.Map('map', options); var layer = new OpenLayers.Layer.Google( "Google Hybrid", {type: G_HYBRID_MAP, 'sphericalMercator': true}); map.addLayer(layer); layer = new OpenLayers.Layer.WMS( "roads", 'http://localhost/cgi-bin/mapserv.exe?map=test.map&;', {layers: 'roads', 'format':'image/gif', TRANSPARENT:true}, {'buffer': 0, isBaseLayer: false, singleTile: true} ); Tried both reprojecting the data in postgis, using +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m [EMAIL PROTECTED] +no_defs OR let mapserver reproject the data. Both give about the same shifts... TIA Richard Duivenvoorde _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users
