[OpenLayers-Dev] Advanced GIS functionnalities

[Brian Levy]

I'm currently working this concept for a client so that we can display a
hierarchy of WMS layers.  Not very difficult, I'm using a treeview component
which allows me to specify the parent of each node.  One thing to keep in
mind is that you must keep the layers indexed properly, otherwise the GetMap
request (when working with OpenLayer.WMS) orders the layers wrong on the
request and some layers are hidden undereath others.

Even though i am unknown and just a lowly user, 

 

I would completly agree to having a grouped layer.  Where you can create
layers inside it and turn them all on or off.

 

I actually think this would be fairly easy.

 

Hmm, maybe i will try making a .js for this one... good idea.

 

On the same note of advanced search queries, i think an identify type button
would be quite excellent, i hardcoded one into my MouseToolbar.js (OL 2.2
release) with a tied event.

We have discussed sub-layers on the WMC/OWS-Context and Mapbuilder lists.

I think the current idea is to set up a "group" flag for a layer so that 
multiple layers can be grouped in a legend in a hierarchical manner.

Could you please expand on your idea of the "Customizable Layer".
