I have multiple tile sources generated using gdal2tiles I'd like to present on the same map. So when presenting a tile I need to determine which source to serve it up from, checking against the bounds.
Anyone know how to calculate the lat lon bounds for a single tile based purely on zoom, x, and y (from the file structure generated by gdal2tiles)? BTW: I'm using Google Maps API v3 in case there's a need to call some functionality from the API to help with calculations.
The reason I'm restricted to purely zoom, x, and y is because the tiles aren't just getting called by an overlay on the map but also some custom print functionality that allows printing outside of the map.
Thanks in advance for any help or suggestions anyone has.
