This package is now DEPRECATED. Its functionality has been incorporated
There's a bad bug in the area calculation in the Matlab routine
geodreckon. Probably, most people calculate areas as part of the
solution of inverse problem using geoddistance; this might explain why
this bug has gone unnoticed for so long. Here is the fix which will be
included in the next release of GeographicLib.

This... is absolutely wonderful. I spent ages looking for a toolbox that would calculate geodesic areas. I figured that my only two options would be to purchase the MATLAB mapping toolbox or write a routine myself. I'm so glad I finally found this. Thank you kindly, sir.
