I just found an online Bible atlas that looks very promising at [url=http://www.biblemap.org]http://www.biblemap.org[/url].  This Bible atlas is based on Google Maps and the ESV Bible.  It even has photos of various historical sites embedded throughout.  Currently in beta, the site has linked 500 geographic locations with 600 to go.  I initially found this through the “Christian blogs” aggregator on the right side of the page, which links to Justin Taylor’s excellent blog, Between Two Worlds.
