Jukka: I have my MapServer mapfile configured for a WFS service and I can perform GetCapabilities and GetFeature queries. Is there a URL syntax to specify filter criteria?

I, too, know very little about mapscript and the documentation is sparse in terms of learning it. I'm curious about WFS queries on a WMS instance. I believe I have my mapfile set up correctly because the layer in question comes up as ows_type="WFS" when I do a WMS DescribeLayer. What else do I need? Will WFS calls work with a WMS instance?

If you do not want to use WFS then I suppose you can do whatever you want with mapscript but that is something I do not know anything about. With some imagination it could be possible to do queries and get vectors out from WMS service and search the bounding box on client side (by using attribute filters inside SLD, or variable substitution inside DATA or FILTER, and by having KML as outputformat). Does not feel like a right way to do even it might be fun to experiment with. I suggest to read about mapscript http://mapserver.org/mapscript/index.html -Jukka- -----Alkuperäinen viesti----- Lähettäjä: David Hildebrand [mailto:david.hildebr...@afsc.ca] Lähetetty: ti 23.11.2010 23:31 Vastaanottaja: Rahkonen Jukka Kopio: mapserver-users@lists.osgeo.org Aihe: RE: [mapserver-users] querying to getting bounding box coordinates Jukka: The examples you used were WFS queries. I wasn't aware that WMS queries also supported filters? =========================== David V.

These examples should work, first is Geoserver and another Mapserver. The latter is pointing to a point layer and therefore I queried two features for getting a reasonable bounding box. http://sigma.openplans.org:8080/geoserver/wfs?service=wfs&version=1.1.0&request=getfeature&typename=states&maxfeatures=1 http://188.64.1.61/cgi-bin/osm-mapserver_i?service=wfs&version=1.1.0&request=getfeature&typename=POI_pub_restaurant&maxfeatures=2 These are just crude examples without the property filter. Queries can be build also so that they do not return attributes. I hope you'll see the idea and think if it could make sense for your use case. -Jukka Rahkonen- -----Alkuperäinen viesti----- Lähettäjä: mapserver-users-boun...@lists.osgeo.org puolesta: David Hildebrand Lähetetty: ti 23.11.2010 22:48 Vastaanottaja: mapserver-users@lists.osgeo.org Aihe: [mapserver-users] querying to getting bounding box coordinates I am running a WMS service with Mapserver in a Windows environment. I want to be able to run a non-spatial query on a parcel layer to return the bounding box (in re-projected coordinates) for a particular parcel. The bounding box and projection will then be used in a WMS query to return a map image. I've never coded server-side functionality with Mapserver so any suggestions would be welcome. Thanks to all. =========================== David V.
