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:<br>
<br>SELECT point_geom,gid,symbol,angle FROM mapdata WHERE category IN(%CATEGORIES%)";<br><br>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?<br>
<br>Thanks,<br>-Adam<br><br><br><div class="gmail_quote">On Thu, Apr 29, 2010 at 6:14 AM, kaipi <span dir="ltr"><<a href="mailto:mapcollect@gmx.net">mapcollect@gmx.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

Hi,<br>
<br>
you can use <a href="http://tilecache.org/" target="_blank">http://tilecache.org/</a> Tilecache with the option metatiling<br>
enabled. With metatiling enabled Tilecache will fetch larger tiles (eg.<br>
4096x4096) from Mapserver and will cut them into smaller tiles (eg.<br>
256x256). It will also increase performance because Mapserver does not need<br>
to render tiles when they are already in cache.<br>
