Could someone please point in the direction of Lat/Lon math.


Specifically, how to calculate distances and how to determine accuracy of a given lat/lon set.


I would love to ready up on this but can't seem to find any detailed information.


Thank you,

well in reference to calculating distance


remember your algebra or geometry...


take the lat difference and the long difference


so lat of pt 2 - the lat of pt 1

and the long of pt 2 -the long of pt 1

and because it is distance use the absolutute value so it is always a positive number


keep smiling and enjoy the life we have been given
