incredible as it might look, i dont see the problem @ all.

It would be timeconsuming, but thats all + it would cost you money to aquire the proper area data, but if you can afford it, or if you´re lucky enough to live in a place where they provide free high quality data then doing something like this is simple enough.

You´ll need some flash magic for the interface of course but that´s not a biggy either and as far as vue goes, i would say that vue is a perfect candidate for a job like this.
