Hi Willem

<BLOCKQUOTE TYPE=CITE>
<FONT SIZE="2">I am seeking assistance from any OpenGIS developer who is willing to help me with GIS studies on WMS. Specific topics are:</FONT>
<OL TYPE=1>
<LI TYPE=1 VALUE=1><FONT SIZE="2">GML Coding</FONT>

Do you need to 'hand-roll' GML or simply generate it by, for example, exporting a shapefile from QGIS or PostGIS as GML? Or consume or generate GML through a web service? Please provide more detail.<BR>

<BLOCKQUOTE TYPE=CITE>
<OL TYPE=1>
<LI TYPE=1 VALUE=1><FONT SIZE="2">GML Application Schema</FONT>
</OL>
</BLOCKQUOTE>
<BR>
Do you need to apply an existing application schema or are you developing one? Again, more detail please.

What about WFS do you need to know? Most web map servers support WFS. What is it you need to do with it?

Here's a whole SLD document that renders empty polygons with red borders and switches them off when you're zoomed in closer than 1:50000. The SLD specification itself from the OGC website is a good resource. Some nice tools to generate SLD include uDIG, Atlas Styler, OpenGeo Styler, QGIS SLD plugin and an ArcGIS SLD extension.<BR>
