Need a great circle calculation
Posted on 2003-10-22
I need a great circle calculation for vbscript.
I just got finished with determining a "nearest store locator" thanks to some help here but I am not smart enough to figure out all the "great circle" info out there...
I have 4 coordinates
I need to know how to calculate the distace between those two points.
I have read about the Great Circle computation method.. but just can't wrap my head around it and I can't seem to tailor the web examples I have found into a useable VBscript.
anyone got anything?
