Good advice from Andrea. I would add that you could consider whether a user needs access to all 110 layers at once. If not, consider splitting the wms in multiple smaller wms services, that are more targeted and focussed on a specific need. I once had a customer that had setup a web map with 220 layers. They were having so much trouble finding layers in the table of contents that they contacted us to ask that we put in a search facility to find things in the tree!

Generally speaking, better to setup thing so that they make sense :-) You can't just merge layers if they have a different set of attributes. If you have a few that are purely geometric or have the same attributes maybe you can merge them and add a classified column, and then use sld rules to tell them apart. For sure you don't want to display a map that has all of 110 layers enabled at the same time, cause that will result in 110 separate queries, but if the layers are legit, that would also result in a map so crowded that is almost impossible to read. So merge layers only if they share the same meaning/attributes (e.g., create a road layers or out "highways", "primary roads", "secondary roads" if you have those as layers), use scale dependencies to show only the layers that it makes sense to show at a certain scale, and allow the user to turn on and off the layer that do not make sense as part of the base map Hope this helps Cheers Andrea ----------------------------------------------------- Ing.
