Advantage WFS vs. WMS

[Bart van den Eijnden (OSGIS)]

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

> for large sets of data WMS is much faster since its just generating and
passing an image, whereas WFS is quite painful with large query sets.&nbsp;
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.&nbsp; Its something like
LAYER_0_FILTER='foo &gt; 5 AND bar &lt; 5' ----- Original Message ----From:

>  [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. Dipl.-Umweltwiss. Kai BehnckeInstitut
