If you absolutely have to do this in JS, then I suggest to see what support you can find in JSTS. Otherwise, it would be lot faster to do this with a servlet.
This is quite straightforward with wfs, but I have never played with your format. > If it is possible, is there likely to be any confusion between this click and > a click-to-drag/pan the map? I have a tool bar with different button to control what function a mouse click does. Ie one for zoom/pan, another for polygon select, another for point queries which is what this is. You enable/disable controls depending on mouse-click. You do need to extend UI beyond basic OL offerings but look at the examples. > > _______________________________________________ > Users mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/openlayers-users -- 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.
