So use two layers. One for the background, use tilecache for that. Then use an untiled wms/mapserver layer for the overlayed points. - Steve ________________________________________ From: mapserver-users-boun...@lists.osgeo.org [mapserver-users-boun...@lists.osgeo.org] On Behalf Of Adam Eskreis [aeskr...@gmail.com] Sent: Thursday, April 29, 2010 1:24 PM To: mapserver-users@lists.osgeo.org Subject: Re: [mapserver-users] Re: WMS and tiles cutting off
I have thought about using tilecache with metatiling, however there is a caveat about this map that i forgot to mention in my main post, and it has to do with that "categories" parameter. Basically, each point/symbol on the map has an associated category in the database backend. I am using mapserver/WMS parameters to change the categories which are called. Each time the user selects a category, only the points in that category are shown. My query in the mapfile looks something like thi: SELECT point_geom,gid,symbol,angle FROM mapdata WHERE category IN(%CATEGORIES%)"; And each time the user changes the categories, I use openlayers to merge new parameters, and input the new category values that should be used. Is tilecache still useable if I have a system like this set up?

With metatiling enabled Tilecache will fetch larger tiles (eg. 4096x4096) from Mapserver and will cut them into smaller tiles (eg. 256x256). It will also increase performance because Mapserver does not need to render tiles when they are already in cache. kaipi -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/WMS-and-tiles-cutting-off-tp4978418p4979280.html Sent from the Mapserver - User mailing list archive at Nabble.com. _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org<mailto:mapserver-users@lists.osgeo.org> http://lists.osgeo.org/mailman/listinfo/mapserver-users _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
