[mapserver-users] Issue in using MapServer WFS Filter

[Kajod Sharma]

Hi Steve,
Thanks for your response.

I have already tried with supplying SRS name in query. Now tried again, but results are still same.
Do you/someone know if I can somehow remove default spatial filter applied while MapServer makes a call to PostGIS?

Thanks. Regards,
Kajod

Try adding &srsName="EPSG:4326"as a parameter
typeName=SampleLayer&srsName=EPSG:4326

Hi,

Greetings!

I hope this is a right platform to discussmy query regarding FILTER applied on MapServer WFS.

I'm new in this area and exploring some featuresof MapServer. I want to use GetFeature request of WFS to get features appliedon any location on map. I'm using "MapServer version 7.0.4 (MS4W 3.2.1)"and trying to apply filter "Contains" for it.

I can see two problems when it applies Filterquery on PostGIS:

1. It looks it adds an extradefault geospatial filter in it while making a query to PostGIS. This defaultspatial filter is not stopping to return any result from PostGIS. Is thereany way to exclude this default filter?
2. It seems Contains coordinatesare not transformed properly according to SRS of data in PostGIS.

I've tries with different projection in mapfile and request message with no success.

Supporting data to give your input on myqueries:

WFS request
*************************
Formatted Version:

http://localhost/cgi-bin/mapserv.exe?
service=WFS&
map=C:/Data/MapServerWFSSample.map&

FILTER=<Filter xmlns="http://www.opengis.net/ogc"xmlns:gml="http://www.opengis.net/gml"xmlns:ms="http://mapserver.gis.umn.edu/mapserver">

    <gml:Point srsName="urn:ogc:def:crs:EPSG::4326">
      <gml:coordinates>0.112034,53.567972</gml:coordinates>
    </gml:Point>
  </Contains>
</Filter>

PostGIS query [Could see in log file]:
*************************
msPostGISLayerWhichShapes query: select "Attribute1","Attribute2","Attribute3",encode(ST_AsBinary(ST_Force2D("wkb_geometry"),'NDR'),'hex')as geom from SampleGeoDataTable where wkb_geometry&& ST_GeomFromText('POLYGON((-0.999462804873474 -1.00102606014116,-0.999462804873474-1.00102606014116,-0.999462804873474 -1.00102606014116,-0.999462804873474-1.00102606014116,-0.999462804873474 -1.00102606014116))',find_srid('','SampleGeoDataTable','wkb_geometry'))and (st_contains(wkb_geometry,ST_GeomFromText('POINT (7853690.3631838141000000-5506204.5232773330000000)'))= TRUE)
*************************

Similar WFS query to GeoServer works perfectly.

It would be very helpful if someone can helpme on it. Thanks a lot in advance.
