[mapserver-users] Re: WFS GetFeature on Mapserver doesn't work

[Rahkonen Jukka]

Hi,

I am sorry but I need to encourage you to do some homework.  Your actual problem right now is most probably somewhere in your source data that comes from PostGIS.  Mapserver works, but it does not find any data and therefore the resulting dataset is empty. I cannot say what you should do in order to make your PostGIS layer work. If you want to see how a successfull GetFeature looks like, read once again the document http://mapserver.org/ogc/wfs_server.html and click the sample GetFeature request http://www2.dmsolutions.ca/cgi-bin/mswfs_gmap?SERVICE=WFS&VERSION=1.0.0&REQUEST=getfeature&TYPENAME=park

You will see that the result set contains the geometry and attributes, but it does also include a reference to DescribeFeatureType request. I copy that part for you here under:

wfs:FeatureCollection xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.0.0/WFS-basic.xsd                         http://mapserver.gis.umn.edu/mapserver http://www2.dmsolutions.ca/cgi-bin/mswfs_gmap?SERVICE=WFS&VERSION=1.0.0&REQUEST=DescribeFeatureType&TYPENAME=park&OUTPUTFORMAT=XMLSCHEMA">

The meaning of the part containing "DescribeFeatureType" is that the xml schema document that describes your feature type can be obtained by running that certain query.  It is how WFS is planned to work.  Try copy-paste with your browser and this url and you should get something interesting reading back:

http://localhost:81/cgi-bin/mapserv.exe?map=d:/Delhi1_wfs_postgres.map&SERVICE=WFS&VERSION=1.0.0&REQUEST=DescribeFeatureType&TYPENAME=delhi_district&OUTPUTFORMAT=XMLSCHEMA
