Bratliff - I can't post a link just yet due to restrictions on the web server I work with. However, I'll post more and probably some code after I see about experimenting more with CANVAS and using what you sent. I don't want info on Google's images/maps, but the overlays I create. After working with this for a bit now, I'm actually surprised more properties/methods aren't available with the overlays. To me there should be built in methods to control the opacity (had to cobble something together for that) and also gleam information from them. Or at least somehow build a legend based on them (maybe that's out there and I just haven't gotten there yet). Otherwise (and especially without opacity), they're just something to look at while covering up other information you might want to see at the same time (i.e. GM Map Types).
I think IE 9 is supposed to support CANVAS, but it's still in beta. There is a work around JS script file called excanvas.js. But, it doesn't contain some of the functionality needed with CANVAS and I've also read that certain operations can really slow down a page. If CANVAS doesn't work, there are a few other things I might be able to do. The server-side mapping suggestion may be something to check into. If a user clicks to retrieve on the map, server retrieves info at that point from the overlay field info that would be stored on the server. Maybe create an info window at user click location with the overaly info. It wouldn't be realtime sampling with the mouse, but it would allow a user to get some useful info about the overlay field. Just thinking outloud. Anyway, I'll be back if I continue to run into walls. Thanks again for your help!

Microsoft pigheadedly refuses to support CANVAS. -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
