Hi, Have you tried GROUP? LAYER GROUP "group_layer" NAME "level_1" STATUS ON TILEINDEX "d:/data/...." MAXSCALEDENOM 14000 ...... LAYER GROUP "group_layer" NAME "level_2" STATUS ON TILEINDEX "d:/data/....." MINSCALEDENOM 14000 MAXSCALEDENOM 100000 WMS clients will show all the layers in a tree with level_1 and level_2 as members of group_layer. However, all your users need to do is to add group_layer into their WMS client. -Jukka Rahkonen- ________________________________

I could customize it to group layers that are essentially the same thing if there was a need for it, but I figured I'd see if this new feature would do that for me for free when I upgrade to ms6. If the UNION layer respected the source layers {min|max}scaledenom settings that would work for me. Are there any other ways to have a single layer provide more detail when zoomed in? Just curious.

This is because the source layers are hidden in most cases (STATUS OFF) to avoid the duplication of the features drawn. However the desired scale range (MINSCALEDENOM, MAXSCALEDENOM) could indeed be taken into account when accessing the source layers, by using a minor change. BTW: How the legend is drawn in your case? As far as I know mapserver draws only the layers in the scale range by default. Best regards, Tamas 2011/5/14 Josh Hevenor <jheve...@rogers.com> This may or may not be relevant but reading RFC 68 got me wondering. I have an application that has shape file data for lakes. There are different shapefiles for data with higher accuracy that are used with scale ranges so that only one is drawn at a time. Specifically something like lakes_1_1m, lakes_1_250k, lakes_1_50k. I'm really looking for a way to show one LAKES layer in the application legend instead of 3 layers, two of which are always out of scale. Can or should I use a UNION layer to connect these layers? What other approach should I consider? Thanks for the advice, Josh _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users No virus found in this incoming message.
