making filtered GetFeatures from WFS?</FONT></SPAN></P>

OpenStreetMap WFS layers the plain GetFeature (possibly with BBOX) does not
yield the most usable data for users. B</FONT></SPAN><SPAN

usage is to use http POST but it is easier to show an example with http GET

<P><FONT size=2 face=Arial><SPAN class=654542909-15052011>Of the existing open
source GIS programs perhaps the best examples about how to build WFS
filters can be found from iGeoDesktop (http://<A
href="http://www.deegree.org">www.deegree.org</A>) and Kosmo (<A
href="http://opengeo.es">http://opengeo.es</A>). Observe that user can also
create spatial filters by using the geometry of a feature that is selected from
the map window. This enables queries like "select features having
ATTRIBUTE1=xxx AND ATTRIBUTE2=YYY within distance of 20km from the selected
feature". </SPAN></FONT><FONT size=2 face=Arial><SPAN
