Jukka, Thanks for your response. It is something odd. This geometry is really tricky an complex, but I tried with other geometries and they were treated correctly by desktop gis applications and mapserver. I tested them with ogrinfo and they were ok. So I've tried what you told me, an it worked. Now I can retrieve the geometry correctly. Thanks for your help.
Best regards.

The result is odd, it tells that the geometry is MULTIPOLYGON EMPTY. That makes me think that Mapserver has perhaps created invalid GML. d:\FWTools2.4.6>ogrinfo -al testgml.gml Had to open data source read-only.

What I have experienced with WFS clients it that very often they cannot get features from WFS services on a map, or they success only with a certain WFS server mark, for example Geoserver of deegree, but not both. Reason may be in a slightly different ways used by clients for building WFS requests, especially with filters. Differences can be bugs, or then both ways are correct but the WFS server has been made to support only one way because developers have been busy with taking care of their own babies and they have not had time or interest to try other client/server combinations for checking the interoperability. It is not uncommon either that WFS server is sending the GML but client fails in parsing it. Sometimes saving the GML on disk and converting it to some other format with ogr2ogr helps because it is not trying to compare GML with all the schemas which are referred. More troubles comes from the big differences between WFS versions 1.0.0 and 1.1.0 like GML2 vs. GML3 and the famous axis order thing. For example, it look like WFS client developers working with deegree jumped into building 1.1.0 and left version 1.0.0 more of less unmaintained, even for many users WFS 1.0.0 would suit better. I saw your were using WFS 1.1.0. Try version 1.0.0 instead, it can be better supported by the clients. -Jukka Rahkonen- David Alda Fernandez de Lezea wrote: > Hi list, > > I'm having some problems loading a getFeature gml file retrieved from > a WFS served by MapServer.
