I have a rather large dataset of lines (1000s of them) which is displayed efficiently enough in WMS. The problem comes when I try to query them. (Eg everything within a user-created polygon). The query works fine, but it returns GML for the geometry and this can be very large. Queries become exceedingly slow. I would normally use this GML to draw the selected features in a vector layer.
At moment, the only solution I can come up with is query against a version of the dataset that has been severely decimated (display proper shape in WMS, and query against generalised layer in WFS). A better solution??? would be return only non-geometry feature fields and there was a way to show the selected feature via a WMS layer. (get server to draw the selected features by WMS with filter and show that layer). Is this possible? -- Phil Scadden, Senior Scientist GNS Science Ltd 764 Cumberland St, Private Bag 1930, Dunedin, New Zealand Ph +64 3 4799663, fax +64 3 477 5232 Notice: This email and any attachments are confidential.
