Hi all,
As noted MapServer does not support gml:Surface. The original request
with gml:Polygon seems to be correct.
Andreas, is it possible to package it and send it to me off list. I can
quickly check what the issue is.
regards,
as noted Mapserver does not support gml:Surface.

Hi,
This one may not be the only problem, but I would start by creating a
valid WFS 1.1.0 request by giving a filter as gml3 or alternatively go
on with using gml2 filter but changing version to WFS 1.0.0. Here
below is a WFS 1.1.0 request that works against deegree. It does not
necessarily work against Mapserver because it can well be that
Mapserver does not support gml:Surface, even if the surface is a plain
polygon as in this case. However, you see that gml3 does not use
<gml:coordinates, it is using <gml:posList and it would be a miracle
or Mapserver bug or both if your request works.

Aihe: [mapserver-users] Spatial Filter with WFS
Dear MapServer-User,
I configured MapServer version 5.6.5 as WMS- and WFS-Server to offer
information about land and properties. I use PostgreSQL/PostGIS
(8.4.4/1.5.1) as datastore in this case. The spatial reference system
is EPSG:25832 und the type of the geometry is MULTIPOLYGON. OS is Suse
Linux Enterprise Server 11, Servicepack1.
WMS and WFS work fine until I use a spatial filter within the
getFeature-Request of the WFS. In this case the response doesn't
deliver any features. Nevertheless the number of features (e.g.
numberOf Features='4') is correct. I tried this out with a couple of
different boundingboxes and the known number of features that
intersect these boundigboxes. In all cases I do not get any features
back, but always the right number. So it seems that at least the
intersection of the boundingbox and my data works correctly.
Please take a look at the following request and response that
illustrate that problem:

Indeed of this behavior the WFS returns features when I do not use a
spatial filter. Therefore in my opinion the WFS should be configured
right in general. To me the spatial filter seems to be the problem.
Unfortunately I do not have any ideas what is going wrong.
For more information you can take a look at my MapFile and a part of
the capabilities document returned from the WFS below:

(The LatLongBoundingBox in this case is obviously not in units of
LatLon but represent the boundingbox in the offered SRS 25832. This
seems to be strange since thes doesn' t occur in the WMS-capabilities
document. In this document the LatLongBoundingBox und the BoundingBox
in the source SRS are both all right.)
I even tried different versions of MapServer and I discovered a slight
difference with other versions. If I change my datasource from PostGIS
to OGR/MapInfo Tab former versions of MapServer (5.4.2/5.2.3) provide
features as well. But just in case of OGR/MapInfo Tab -- not with
PostGIS in use! As I have to use PostGIS I'm interested in any hints
to solve this problem.
Therefore I would be glad to hear from you!
Thanks so far and best regards!
Andreas
