[Geoserver-users] Antw: WFS GetFeature and BBOX Filter

OK- that works as a XML-Request (eg. in GeoServers Demo Section)
But what is the syntax for an URL based Request ?
And the second question is, why does'nt know GeoServer the gml:box tag,
though it is defined in the OGCWFS specification
Version 1.0.0, page 69/example 13 ?
I'm really confused about the spatial-filters usability, especially I
didn't get any problems using the nonspatial filters.

cheers!

Sorry, should have known that.

Try this example filter instead of your first filter:

<ogc:Filter>
         <ogc:And>
            <ogc:BBOX>
               <ogc:PropertyName>gsml:shape</ogc:PropertyName>
               <gml:Envelope>
                  <gml:lowerCorner>-25 115</gml:lowerCorner>
                  <gml:upperCorner>-20 120</gml:upperCorner>
               </gml:Envelope>
            </ogc:BBOX>
            <ogc:PropertyIsEqualTo>
              
<ogc:PropertyName>gsml:classification/gsml:LithostratigraphicUnit/gml:name</ogc:PropertyName>
              
<ogc:Literal>urn:x-cgi:desc:unit:GSWA:2001:HammersleyFm</ogc:Literal>
            </ogc:PropertyIsEqualTo>
         </ogc:And>
      </ogc:Filter>

Hi Kris,

thanks for your hint, but it does'nt seem to work !

this is the response :
...
filter and bbox both specified but are mutually exclusive
Details:
org.geoserver.wfs.WFSException: filter and bbox both specified but are
mutually exclusive
...

You can pass the bbox values in the request parameter BBOX instead of
specifiing it in the filter

request should then be:
<A
href="<A
href="http://kataster1/geoserver/wfs?request=GetFeature&amp;amp;TYPENAME=kvla:str_geom_erw&amp;amp;VERSION=1.0.0&amp;amp;SERVICE=WFS&amp;amp;BBOX=Filter=str_nameF*http://kataster1/geoserver/wfs?request=GetFeature&amp;TYPENAME=kvla:str_geom_erw&amp;VERSION=1.0.0&amp;SERVICE=WFS&amp;BBOX=4505000,6005000,4507500,6006600Filter=http://kataster1/geoserver/wfs?request=GetFeature&amp;TYPENAME=kvla:str_geom_erw&amp;VERSION=1.0.0&amp;SERVICE=WFS&amp;BBOX=Filter=str_nameF*http://kataster1/geoserver/wfs?request=GetFeature&TYPENAME=kvla:str_geom_erw&VERSION=1.0.0&SERVICE=WFS&BBOX=4505000,6005000,4507500,6006600Filter=&lt;Filter&gt;&lt;PropertyIsEqualTo&gt;&lt;PropertyName&gt;str\_name&lt;/PropertyName&gt;&lt;Literal&gt;F\*&lt;/Literal&gt;&lt;/PropertyIsEqualTo&gt;&lt;/Filter&gt;

I didnt test the request so there maybe a bug in it.

Succes

Hi all,

I'm trying to build a Query for a set of features, that lie within a
specified Box and additional filtered by an attribute.
Following the WFS-Specification-Document from the OGC this is the
result from my hard work :wink:

<A
href="<A
href="http://kataster1/geoserver/wfs?request=GetFeature&amp;amp;TYPENAME=kvla:str_geom_erw&amp;amp;VERSION=1.0.0&amp;amp;SERVICE=WFS&amp;amp;Filter=http://kataster1/geoserver/wfs?request=GetFeature&amp;TYPENAME=kvla:str_geom_erw&amp;VERSION=1.0.0&amp;SERVICE=WFS&amp;Filter=http://kataster1/geoserver/wfs?request=GetFeature&amp;TYPENAME=kvla:str_geom_erw&amp;VERSION=1.0.0&amp;SERVICE=WFS&amp;Filter=http://kataster1/geoserver/wfs?request=GetFeature&TYPENAME=kvla:str_geom_erw&VERSION=1.0.0&SERVICE=WFS&Filter=&lt;Filter&gt;&lt;And&gt;&lt;PropertyIsEqualTo&gt;&lt;PropertyName&gt;str\_name&lt;/PropertyName&gt;&lt;Literal&gt;F\*&lt;/Literal&gt;&lt;/PropertyIsEqualTo&gt;&lt;Within&gt;&lt;PropertyName&gt;the\_geom&lt;/PropertyName&gt;&lt;gml:Box&gt;&lt;gml:coordinates&gt;4505000,6005000
4507500,6006600>/gml:coordinates></gml:Box></Within></And></Filter>

But I only get this error message :
( I use GeoServer-1.6.0RC1 )

cheers!
Ronald
