Re: [UMN_MAPSERVER-USERS] help w/ WFS request

Sorry I meant DescribeFeatureType instead of DescribeLayer ....

Hi John,

1) what Mapserver version are you using?

2) if you do a DescribeLayer request, what is the name of the geometry property (is it really the_geom like in your request)?

Mapserver's response indicates an empty feature collection, so the boundedBy is gml:null.

Best regards,
Bart

Hello All,

I'm trying to get mapserver setup as a simple WFS server. It responds to a GetCapabilities request OK:

but when I send the following GetFeatures request:

<wfs:GetFeature service="WFS" version="1.0.0"
 outputFormat="GML2"
 xmlns:wfs="http://www.opengis.net/wfs";
 xmlns:ogc="http://www.opengis.net/ogc";

 xsi:schemaLocation="http://www.opengis.net/wfs

http://schemas.opengis.net/wfs/1.0.0/WFS-basic.xsd";>

 <wfs:Query typeName="soundings">
   <ogc:Filter>
     <ogc:BBOX>
       <ogc:PropertyName>the_geom</ogc:PropertyName>
       <gml:Box srsName="http://www.opengis.net/gml/srs/epsg.xml#4269";>
          <gml:coordinates>-95,26.5 -94.75,26.75</gml:coordinates>
       </gml:Box>
     </ogc:BBOX>
  </ogc:Filter>
 </wfs:Query>
</wfs:GetFeature>

I get this response, and don't know what's wrong:

<?xml version='1.0' encoding="ISO-8859-1" ?>
<wfs:FeatureCollection
  xmlns:ms="http://mapserver.gis.umn.edu/mapserver";
  xmlns:wfs="http://www.opengis.net/wfs";
  xmlns:gml="http://www.opengis.net/gml";
  xmlns:ogc="http://www.opengis.net/ogc";
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";

xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengeospatial.net/wfs/1.0.0/WFS-basic.xsd http://mapserver.gis.umn.edu/mapserver http://lynx.ngdc.noaa.gov:8000/cgi-bin?map=bathydb&SERVICE=WFS&VERSION=1.0.0&REQUEST=DescribeFeatureType&TYPENAME=soundings&OUTPUTFORMAT=XMLSCHEMA";>

  <gml:boundedBy>
     <gml:null>missing</gml:null>
  </gml:boundedBy>
</wfs:FeatureCollection>

It suggests to me that the bounding box coordinates are not being properly read. I would have expected something like in the response:

<gml:boundedBy> <gml:Box srsName="EPSG:4326">
<gml:coordinates> -95, 26.5 -94.75, 26.75</gml:coordinates>
</gml:Box>
</gml:boundedBy>

followed by a series of featureMember elements.

Can someone tell what I'm doing wrong?

Thanks!
