So I ran across this: http://webdev.stephband.info/parallax.html
And a couple of the demos looked like they could get used with mapping....
Image a city map with mupltiple building levels: http://webdev.stephband.info/parallax_demos.html
Imagine a space sector map with system layers framed inside this grid: http://webdev.stephband.info/parallax_demos_target.html
All iot needs are transparent images...
