Re: [UMN_MAPSERVER-USERS] WMS question

[rock well]

Hi Bart, i am trying to use sld_body to specifiy the path of the localurl for the xml file, but i get a blank image, i didnt really get the concept of how to write an xml file and then send it through the sld_body tag, can you suggest me with a real time example where a clear description is given as to how to specify the map file in the xml ...

 

well i guess i might have understood something wrong, but can you/anyone suggest me ...

 

i cut down my xml file to the following lines as i dont know what other lines mean

 

<StyledLayerDescriptor version="1.0.0">

<NamedLayer>

<Name>Layer Name</Name>

</NamedLayer>

</StyledLayerDescriptor>

 

Thanks for your time

This can be accomplished using SLD. In a WMS GetMap request you can add
an inline SLD using the SLD_BODY parameter, or use the SLD parameter to
point to a URL pointing to the actual SLD XML document.

The Chameleon ExpressionBuilder widget has some code to do this or check
out:

http://mapserver.gis.umn.edu/docs/howto/sldhowto/?searchterm=SLD

If a WMS layer is queryable, you can perform a WMS GetFeatureInfo
request against it using an X and Y value in pixels, which can return a
plain text, HTML or GML document.

Best regards,
Bart
