CQL wildcards & filtering WMS GetFeatureInfo
by Josh Marcus-2

Rate this Message:
Hey folks,
I have two separate questions, related to my goal of presenting a map with a filter and then obtaining information about features through WMS's GetFeatureInfo. #1 -- Does Geoserver support wildcards in CQL? For example, if I'm using the topp:states openlayers map preview, I can't get a query like: STATE_NAME="Ut*" to work, even though * and ? are in the CQL specification. #2 -- I am trying to generate a map using a filter, and then use WMS's GetFeatureInfo to get information about features. I don't want features to be included that were excluded by the filter. 2a) Will GetFeatureInfo respect SLDs, in particular the filter in an external SLD? I've tried this but it doesn't seem to work. 2b) GetFeatureInfo seems to be crashing when I try to use an OGC Filter. For example, if I use the topp:states open layers preview/demo, and enter: <PropertyIsEqualTo><PropertyName>STATE_NAME</PropertyName><Literal>Utah</Literal></PropertyIsEqualTo> or <Filter><PropertyIsEqualTo><PropertyName>STATE_NAME</PropertyName><Literal>Utah</Literal></PropertyIsEqualTo></Filter> for an OGC filter, and then click Utah (the only visible state), I get ... org.geoserver.platform.ServiceException:
org.xml.sax.SAXParseException: XML document structures must start and end within
the same entity. org.xml.sax.SAXParseException: XML document structures must
start and end within the same entity. XML document structures must start and end
within the same entity. --j ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Geoserver-users mailing list Geoserver-users@... https://lists.sourceforge.net/lists/listinfo/geoserver-users |

After looking at the geotools source, I've figured out that the CQL syntax in geotools for wildcard searches is SQL-like: ATTRIBUTE LIKE '%foo'. But I'm still curious about my second question.

Assuming you mean PNG og GIF output through WMS, append transparent=true
to the URL. In OpenLayers this is an option you pass to the constructor of the WMSLayer. -Arne Daniel Gorni wrote: > Hi all, > > My name is Daniel, from Brazil.

Mumble, interesting, I thought the parser was completely CQL compliant. Mauricio, cc'ed, is the developer of the CQL parser. Mauricio, can you shed some light on this mystery? > 2a) Will GetFeatureInfo respect SLDs, in particular the filter in an > external SLD? I've tried this but it doesn't seem to work. Nope, it won't. We have a Jira issue open to track this: http://jira.codehaus.org/browse/GEOS-1008 but there has been no push to actually solve it since the full solution (one that takes into account the symbolizer size and not only the filters) is not trivial to implement. > 2b) GetFeatureInfo seems to be crashing when I try to use an OGC Filter. Hum... which version of GeoServer are you using and what error message are you getting? I've tried the following request (properly url-encoded): http://localhost:8080/geoserver/wms?bbox=-130,24,-66,50&styles=population&Format=image/png&request=GetMap&layers=topp:states&width=550&height=250&srs=EPSG:4326&filter=%3CFilter%3E%3CPropertyIsEqualTo%3E%3CPropertyName%3ESTATE_NAME%3C/PropertyName%3E%3CLiteral%3EUtah%3C/Literal%3E%3C/PropertyIsEqualTo%3E%3C/Filter%3E and it works fine on both a GeoServer 1.6.2 and a GeoServer 1.7.0-beta1. Let me know Cheers Andrea ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Geoserver-users mailing list Geoserver-users@... https://lists.sourceforge.net/lists/listinfo/geoserver-users |

The user seemed to expect that expression to act as a LIKE.

String and text patterns are similar: quote , characters, .. quote. So, the way used by the parser to know what is the rule to use is looking lthe prefix “=” or “like”. cheers -- Mauricio Pazos www.axios.es Tel.: +34 94 682 42 86 ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Geoserver-users mailing list Geoserver-users@... https://lists.sourceforge.net/lists/listinfo/geoserver-users |
