Hi, see:
http://dev.openlayers.org/releases/OpenLayers-2.11/doc/apidocs/files/OpenLayers/Protocol/WFS/v1-js.html#OpenLayers.Protocol.WFS.v1.read the section under "To limit the attributes returned by the GetFeature request". Best regards, Bart > I'm querying a WFS service (from Geoserver). The problem is, the dataset > is > very large, and most of it is irrelevant to what I'm doing in OpenLayers. > In > this context I'm only interested in retrieving the points from the server, > not the 100+ additional properties. > > > I can construct a URL by hand to get what I want - every point, but only > the > position - like this: > > http://ubuntu-geospatial-server:8080/geoserver/wfs?service=wfs&version=1.1.0&request=GetFeature&typeName=underway:ss2011_v03&propertyName=position > > However I haven't been able to work out the equivalent in OpenLayers. > Filters will let me get, say, all the points in a certain period, but it > will still return the full dataset, which is causing performance problems. > > I've looked through the API, mailing lists and Google, and I haven't been > able to find any answers. Any help is much appreciated. > > -- > View this message in context: > http://osgeo-org.1803224.n2.nabble.com/Limit-number-of-properties-returned-WFS-tp6857679p6857679.html > Sent from the OpenLayers Users mailing list archive at Nabble.com. > _______________________________________________ > Users mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/openlayers-users > _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users
