This is a general question about visualization of themes in a Layer
My first thoughts were to build something that shows all Layers
available from a MapServer in all view levels to be displayed for
toggling the Layers on/off.
Different LAYERs have different MIN/MAX scales. The question is, how
have other tried listing all Themes and still make it obiuos (visually)
to the user, that a Theme is available or not available for a particualr
I've done similar controls by simply showing only those Layer that are
pertinent to the current view. But it would be nice if the Control
could display when a particular theme is available for viewing at
specfic scale values.
Related to this, I had though about possibly building a Control that
would use some sort of sliding scale for each theme that would indicate
to the user where in the server scale range thier particualr View was,
and also where each particular theme would come into view.
I'll mock something up after I send this.
anyone have similar ideas, or am I too far left with the idea(s)
