[OpenLayers-Users] Limit number of properties returned - WFS

[Bart van den Eijnden (OSGIS)]

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

> 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.

> able to find any answers. Any help is much appreciated.
