Hi, Feel free to test with my TinyOWS server at http://188.64.1.61/cgi-bin/tinyows. I would not encourage you to use BBOX filter for finding features. According to the standard BBOX is a synonyme for Intersects but for example Geoserver is using it in a bit different way. It is comparing if feature bounding boxes are intersecting with reference bounding box if BBOX is used. This suits perfectly for filling a screen with features because feature bounding boxes can be found fast from the spatial index of a database. However, with lines and polygons this search is sometimes finding extra features. Intersects is doing a real comparison of geometries which is accurate but slower. If you click on a map why don't you use ogc:Contains for finding polygons or ogc;DWithin filter for finding all kind of features with a buffer?
My TinyOWS has a bug with ogc:BBOX so if you test it, use Intersects, Contains, or DWithin instead. Naturally WFS should behave in a similar way independently of the data source behind the server. -Jukka Rahkonen- > -----Alkuperäinen viesti----- > Lähettäjä: Dejan Gambin [mailto:[email protected]] > Lähetetty: 14. marraskuuta 2011 15:33 > Vastaanottaja: Rahkonen Jukka > Kopio: '[email protected]' > Aihe: Re: [mapserver-users] MapServer crash with WFS > GetFeature request using multiple typenames > > Hello Jukka > > Thanks for the information.
