This class should make it easy for you. It calculates the distance between two points on the earth sphere. The example shows how easy it is to use as well.
I hope this helps. |

This class will calculate the distance between two points and perform a conversion from miles to whatever unit you are after. If I am reading it correctly, the formula (which is in the class) is for a straight line and does not take into account the curvature of the earth, so it may be off slightly. |
