Thanks for the feedback. Would you say the Yahoo approach is the best approach? Are there other ways to skin this cat?
I didn't realize it, but after seeing Kelly's reference (http://www.flashearth.com/) I would really like to implement a rotating canvas. How easy would that be to implement? The tile libraries are actually already taken care of. We will not necessarily be doing the whole earth. We'll mostly be dealing with small geographies and custom-generated tile sets. --- In [email protected], "Igor Costa" <[EMAIL PROTECTED]> wrote: > > Man, > > just take a look at the Flash Developer center of Yahoo! > > regards > > On 10/7/06, atlasalive <[EMAIL PROTECTED]> wrote: > > > > I'm prototyping a map viewer application similar to Google or Yahoo > > maps.
