A few people have picked up on this. Bible Geocoding from OpenBible means you can now find every place named in the Bible on Google Earth. You can view places for the whole Bible, or individual books. And if you don’t want to open up Google Earth, you can view the information for individual books in a browser window thanks to Google Maps.
But there’s more… An atlas of place names with their linked Bible references. And links to photos of locations in the Bible. However, they do admit, "These photos use the Flickr and Panoramio APIs
and are thus of varying quality—many of them just happen to be of
people or places near the ancient locations."
Then there’s overlays of historic maps which integrate with Google Earth terrain data.
The whole site is well worth a look.
