Please note that the filter given here is not WMS, its Mapserver's native query language, so it can at most be seen as a vendor-specific parameter.
The way to do this with WMS is to use SLD. Best regards, Bart -- Bart van den Eijnden OSGIS, Open Source GIS http://www.osgis.nl --------- Oorspronkelijk bericht -------- Van: Curtis W.

Its also faster in web based clients to handle because javascript although nice in most web based WFS clients its very slow to drag them around (think openlayers).Also with WMS and mapserver you can query by GET arguments i just can't remember how at the moment. Its something like LAYER_0_FILTER='foo > 5 AND bar < 5' ----- Original Message ----From: Kai Behncke <[EMAIL PROTECTED]>To: [EMAIL PROTECTED]: Monday, January 29, 2007 1:10:13 AMSubject: > [UMN_MAPSERVER-USERS] Advantage WFS vs. WMSHello list,I would like to know what the advantages of WFS in comparison to WMS are?Some aspects are quite clear:-It`s easier to design a WFS than a WMS. The way with SLD is not necessary.- Poissibility to analyze and select WFS-Features with Filters (at WMS just aspatial analyze with BBOX is possible)- Tooltip-possibility- HighlighfunctionDoes anybody know other advantages WFS gives in comparison to WMS?Thank you, Kai --Dipl.-Geogr.
