Added mouse-over coordinates to the Google Maps version of the heatmaps:

They're probably not 100% accurate, but should be a good approximation. It's relying on the API's way of converting Mercator projection Lat/Long coordinates, so there's probably some precision loss converting back to Cartesian coordinates on a flat map.
