1) I have several layers in a layer switcher. I would like to attach
custom behavior to the layers
- attach an URL to each of them
- show a tip while mousing over
- etc.
How should I proceed
2) How can I have two or three different layer switchers and control
which layer goes in each switcher?
I would strongly consider looking at using GeoExt on top OL and using
the layer tree. (Example at
http://data.gns.cri.nz/dataportal/ - free registration required but then
look at the interactive maps).
