Spatial filter in SLD

[Yewondwossen Assefa]

i There,

  I have checked a bit this issue. There were a couple of bugs related
with DWithin and Intersect spatial filters. There is a new version of
mapogcfilter.c (r 1.31). You should give it a try.
Another note on using the applysld from php with spatial filter (based
on your example) : there are no class created for the layer since the
filter is only a spatial filer. What happens is that the spatial filter
is converted into a query in mapserver and applied to the layer. If you
are doing your tests throuh php you should use drawquery to see the
effect of the sld.

Let me know how it goes.
