Re: [mapserver-users] MapServer 7.4.3 - Poor projection from British National Grid (EPSG 27700) to WebMercator (EPSG 3857)
Ben Have you considered using PostGIS to do the transformation instead? Also, depending on the amount of data you could set up some material views building transformed data or similar which may make it more responsive, if that is needed.

My deployment uses a full compressed build of the openlayers.js file with some changes to vml.js (uses vml textpath - for = IE8) and svg.js (uses text rotation - for Chrome and Firefox). This file comes in at 927 KB. I created a custom compressed build of the openlayers.js file, again including the vml and svg changes. The new file comes in at 443 KB; a very significant drop in size. Both files were built using the latest, hot off the press, OpenLayers-2.12-rc6. Prior to creating and using the new, smaller openlayers.js file, I tested the time to get the first raster image tile from boot up with the larger file which was 16 seconds. I did a one click zoom to the first layer that has PostGIS sitting behind it and that took a further 8 seconds. After that initial load of both layer types, everything is speedy with very little delay at all. I then substituted the new, smaller openlayers.js file and repeated the process from boot up. Low and behold, I get exactly the same results: 16 seconds then 8 seconds. Whilst there is probably a time saving in terms of milliseconds, the perceptional difference is nil. However, I do agree that the smaller openlayers.js file is the way to go in terms of reducing unnecessary initial traffic and also having less javascript in memory; something that will no doubt aid Internet Explorer speed-wise as that particular platform is chronic at best.

Re: [mapserver-users] query mode, multiple selections
Hi We use the back end CGI extensively and it is extremely fast. It is simply a case of being able to define what type of constraint you want against each layer (tolerance etc) - I'm normally surprised if mapserver takes more than a second or two to query up to 20-30 individual layers... Hope this reassures! Mike 2009/9/1 Chris Kantarjiev c...@speedgauge.net Sure. The basic use case is: User navigates to a particular, known, lat/lon as starting point; this can be by entering the known lat/lon values, or by navigation around cities. User then selects one or more links and can inspect attributes associated with those links - in particular, link_id and direction. Initial selection could be by sweeping out an area, but should also provide a way of adding/removing specific links from the selection (control-select). Did that makes sense? chris Steve Lime wrote: You'd be surprised with what you can do with the CGI backend. It's certainly possible, with the right web client (e.g. something like GeoMoose or OpenLayers) to craft queries against the CGI to select one or many features from one or many layers using a point, box or arbitrary geometry. Perhaps if you could sketch out a use case or two...

Excellent - that works!
FYI - This is why I believe that Open Source can easily prevail even when
people put down the 'many eyes see more bugs' notion. In another life I
worked with / as a partner for a proprietary company (now you can buy
franking machines from the same parent company wink wink nudge nudge) and
you'd never get this response so quickly and also having 'had it from the
horses mouth a.k.a. Developers' that there is an issue and this is the best
way around it.
Thanks so much Alexandre

You should use a regular expression instead like the following :
