It has Google Earth files locating all the identifiable places in the Bible for the whole Bible, by individual book, or by individual chapter! The files can also be viewed in Google Maps by selecting the preview option.
Another way to view the sites is by alphabetical order in the Bible Atlas page. Here each site is linked to the Bible passage where it is mentioned.
Finally, there is an overlays page which features maps of old and modern Jerusalem which can be imported into Google Earth or viewed online.
Job well done OpenBible.info! (Hat tip: Google Earth Blog)
