----------------------------Original message---------------------------- ----------------------------Original message---------------------------- Help! A man just called and wants to know if there is a formula for computing the distance in meters between "Point A" and "Point B" if he knows the coordinates for each point. Does anyone know? This is beyond me.

I remember it gets fairly technical depending on the latitude (or is it the longitude?). That and a good IBM computer and a bottle of aspirins should do it. ********************************************************************** April Carlucci [log in to unmask] The British Library Voice +44 171 412 7000x4167 Map Library +44 171 412 7703 Great Russell Street Fax +44 171 412 7780 London WC1B 3DG United Kingdom "Nobody expects the Spanish Inquisition!" **********************************************************************
