  11. Does anyone have a "C" routine that converts earth longitude and latitude
  12. coordinates to distance traveled?
  13.  
  14. Ideally the routine would look like this:
  15.  
  16.     DistanceTraveled(StartingLat,StartingLong,EndingLat,EndingLong)
  17.  
  18.  
  19. Note that I am looking for something that takes the earth's ellipsoid shape
  20. into account; I've written the spherical approximation version of this.
  21.  
  22.         Any pointers are appreciated.
