I found a web site that explains in great detail exactly how to do
these calculations.

It provides three seperate equations, depending on how precise you are
interested in being, and how precise the equipment you are using is.
(The Most precise equation requires 15 digits of accuracy.)

the above links are for:

#1) longitude & latitude tools

#2) where I found a great converter, so you don't have to do all that
messy math yourself!!!

happy sailing ;)

There I go, letting myself get over-focused. I should have thought to
provide links like that myself. Thanks for the assist, quartney-ga. :)

I have a javascript calculator I saved on my laptop (I use it during
hurricane season for estimating earliest landfall). I found it at
http://williams.best.vwh.net/gccalc.htm and saved it to my disk for
off line use.

Google search criteria was great + circle +calculator.

"This service uses data from the US Census and a supplementary list of
cities around the world to find the latitude and longitude of two
places, and then calculates the distance
[http://www.indo.com/distance/distance-details.html] between them (as
the crow flies). It also provides a map showing the two places, using
the Xerox PARC Map Server [http://pubweb.parc.xerox.com/map].

Various query formats [http://www.indo.com/distance/dist-formats.html]
are allowed; for example:
