Re: [OpenLayers-Users] Vector-like feature interaction with large, complex layers

Hi Tom, When your geometries are too many or too complex (or both) you need to compromise somewhere. There are 2 more approaches you can take: 1) Use an approach similar to what Eric mentioned. Use a WMS layer, but on hover send a request to the server to get the id (and possible other attribu

Thanks, Ian; hm, many of the polygons we're using are adjoining, like counties, and my guess is that generalizing them would make their borders a bit messy, and it might be a bit of work to try it out. I'll ask our GeoServer/OL support person what he thinks about it, though. Any other ideas for

Hi all, I've read about a couple of methods (clustering strategy, choosing WFS or WMS based on zoom level) for working around the issue of WFS layers being unusable for performance reasons when large numbers of complex features are involved. Neither of these are terribly good solutions for our m
