[Freegis-list] Distance between two points

[Martin Reddy]

There's a discussion of this problem in the GIS FAQ:

  http://www.census.gov/cgi-bin/geo/gisfaq?Q5.1

The C++ package GFC (Geodesy Foundation Classes) contains source code
to do the calculation. Go to www.freegis.org and search for GFC.

Cheers,

Martin.
