Re: [mapserver-users] MODE=legendicon GROUP Layers
Certainly our mapfiles stay fairly static once we've set them up. Thanks for the suggestion, will have a look at trying it out.

You have complete control over the legend this way and can mix and match data sources however is required without needing to actually map the data out. It is more work overall, but if your MapFiles don’t change often, it’s usually a one time setup thing. I have a few map layers that have 7 or 8 different thresholds for display set MIN/MAXSCALEDENOMs and they all get a dummy layer that displays the same thing for all thresholds.

Re: [mapserver-users] MODE=legendicon GROUP Layers
Thanks for the info Steve, that makes sense - when Groups are used to link related layers things get too ambiguous. We'll look at our options with this one.
