Hi Clément, Under your MAP you can specify an OUTPUTFORMAT tag. See http://mapserver.org/mapfile/outputformat.html for details. There's also some additional information about the format options at the bottom. Use AGG for best quality results.

RE: [mapserver-users] Feature select performance
Like with everything it depends... Selection of features via a bounding box shouldn't be much, or really any, slower than drawing since it's basically the same mechanism for both. Attribute queries can be quite slow with shapefiles since MapServer doesn't do any attribute indexing. That's where the RDMS really adds value. There shouldn't be much of a difference with a bbox query, and in fact, a local shapefile will probably be faster, even on larger datasets as long as you've build an spatial index file. Anyway, it's what you do with results afterwards that matters and that's probably specific to your application. I've used query files to persist selected features over many map draws successfully on modest (50,000 feature) sized shapefiles.

Re: [mapserver-users] Feature select performance
Steve I was pursuing the performance issue on the pmapper mailing list too. It transpires it is related to browser performance (from a JS aspect) for the web apps query/redraw processes - IE7 - awful (8mins), IE8 and FF pretty good - around 20secs for returning/highlighting 5000 features (and building results table) and Chrome about 13 secs, that is without even creating a spatial index. Thanks for the info and I think I may even not have to go down the db route (which keeps life simple!) just advise IE6/7 users to switch browsers (not the first webGIS app I know that does this!)
