[mapserver-users] hiding / combining layers in a wms service

[Travis Kirstine]

I am trying to combine several layers into a single layer for a wms
server while using the wms_layer_group option.  I have resampled my
source tifs so that is displayed based resolutions and map scale to
hopefully improve performance.  The drawback to this is that clients
see all layers.  Is there a way to group all layers into one while
keeping the hierarchy that is created with the wms_layer_group.
