A VERY simplified quick translation to AS.. (seems to work? I need to
test some coordinates next)..
lat1(;lon1?2.3;
lat2 ;lon2?0.0;
var miles;
var dlon;
var dlat;
var a;
var c;
var factor;
factor = (2*Math.PI)/180
lat1 = lat1 * factor;
lon1 = lon1 * factor;
lat2 = lat2 * factor;
lon2 = lon2 * factor;
dlon = lon2 - lon1;
dlat = lat2 - lat1;
a = (Math.sin(dlat/2))*(Math.sin(dlat/2)) + Math.cos(lat1) *
Math.cos(lat2) * (Math.sin(dlon/2))*(Math.sin(dlon/2));
c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a) );
miles = 3961 * c;
trace(miles);
....Jayson
