Hi there.. I have an openlayers application overlaying some WMS layers (that i am serving locally from geoserver) over the top of google maps. Everything is running perfectly there using the " 'sphericalMercator': true" parameter in the googlemaps layers' config. What I am trying to do now is point openlayers at my tilecache instead of directly to geoserver for my local wms layers. I have previously got this working no worries when no google layers were involved. I have read a lot of information about getting tilecache to work when using google maps as the client, but is it able to request tiles when openlayers is the client (and google is involved) ? I have aligned the 'resolutions' parameter between openlayers and tilecache, and used the tms_type and spherical_mercator tags in TC but still tilecache returns: An error occurred: Current x value 8004688.542400 is too far from tile corner x 7514065.626400 So the problem is aligning openlayers with tilecache.. but i can't see what i'm missing. Is what i'm trying to do even possible ? Any comments or suggestions would be greatly appreciated. cheers, -ivan heres my tilecache config: [landsat] type=WMS url=http://localhost:8080/geoserver/wms extension=jpeg resolutions=156543.033900000,78271.516950000,39135.758475000,19567.879237500,9783.939618750,4891.969809375,2445.984904688,1222.992452344,611.496226172,305.748113086,152.874056543,76.437028271,38.218514136,19.109257068,9.554628534,4.777314267,2.388657133,1.194328567,0.59716428337097171575,0.298582142 srs=EPSG:900913 maxResolution=156543.0339 bbox=-20037508.3427892,-20037508.3427892,20037508.3427892,20037508.3427892 tms_type=google spherical_mercator=true layers=xxxxx openlayers layer config: map = new OpenLayers.Map('map', { controls: [], resolutions: [156543.033900000,78271.516950000,39135.758475000,19567.879237500,9783.939618750,4891.969809375,2445.984904688,1222.992452344,611.496226172,305.748113086,152.874056543,76.437028271,38.218514136,19.109257068,9.554628534,4.777314267,2.388657133,1.194328567,0.59716428337097171575,0.298582142], projection: new OpenLayers.Projection("EPSG:900913"), displayProjection: new OpenLayers.Projection("EPSG:4326"), units: "m", maxExtent: new OpenLayers.Bounds(-20037508.34, -20037508.34, 20037508.34, 20037508.34) numZoomLevels: 18, maxResolution: 156543.0339 }); (cut) var layer_image_landsat = new OpenLayers.Layer.WMS( "Local Imagery", "/tilecache/tilecache.cgi", { layers: 'landsat', srs: 'EPSG:4326', format: 'image/png', transparent:true }, { isBaseLayer: true, singleTile: false, opacity:1} ); (cut) |
