[Freegis-list] Distance on the surface on the spherical Earth

[Ahmed Gelchu]

Dear Friends,

I need to compute the shortest distance between two points on the surface of
the earth. In short, I am looking for a software that could compute distance
between two points, given the lat-long coordinates for the two points? any
help is appreciated

Thanks,
