(Apologies for posting to both lists - not sure which one it belongs in!). I have Tilecache 1.9rc3 running as a CGI, and have had trouble getting my OpenLayers overview map to display anything since. If I look in Firefox at pageinfo->media, I find that the tiles which should have displayed my overview map are zero length, and if I type one such URL e.g:
http://10.48.1.76:8084/?LAYERS=Coastline%20and%20bathymetry&STYLES=sggis_bathymetry_polygon%2Csggis_coastline&FORMAT=image%2Fpng&TRANSPARENT=off&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A2007056&BBOX=-1616%2C61560%2C-1104%2C62072&WIDTH=256&HEIGHT=256 into the browser, I get the following error: An error occurred: can't find resolution index for 2.000000. Available resolutions are: [200.37037000000001, 100.185185, 50.092592500000002, 25.046296250000001, 12.523148125000001, 6.2615740625000003, 3.1307870312500001, 1.5653935156250001, 0.78269675781250003, 0.39134837890625002, 0.19567418945312501, 0.097837094726562504, 0.048918547363281252, 0.024459273681640626, 0.012229636840820313, 0.0061148184204101565, 0.0030574092102050783, 0.0015287046051025391, 0.00076435230255126956, 0.00038217615127563478] The overview map is given the following options: var sgOverviewOpts = { 'maxExtent' : new OpenLayers.Bounds(-82000,7800,80000,116000), 'maxResolution' : 200.370370, 'minResolution' : 0.5, 'units' : 'm', 'projection' : EPSG:2007056 }; var overview = new OpenLayers.Control.OverviewMap(sgOverviewOpts); map.addControl(overview); which are the same as I give my Coastline/bathymetry base layer. My tilecache.cfg contains the following for the same layer: [Coastline and bathymetry] type=WMSLayer url=http://10.48.1.76:8080/geoserver/wms?transparent=off layers=sggis:bathy_poly,sggis:coast_polygon extension=png bbox=-82000,7800,80000,116000 maxResolution=200.370370 srs=EPSG:2007056 Regular tiles for the map appear fine. It's just when tiles are fetched for the overview map that the problems arise. Any idea how I get round this?
