 How Far Is It?  Bali Online
http://www.indo.com/distance/
This service uses data from the U.S. Census and a
supplementary list of cities around the world to find the
latitude and longitude of two places, and then calculates
the distance between them (as the crow flies). It also
provides a map showing the two places, using the Xerox
PARC Map Server, and can supply driving directions.
