GetDistance()
Summary
Computes the great circle distance between two coordinates.
Syntax
dist = GetDistance(coordinate c1, coordinate c2)
| Argument | Contents |
|---|---|
| c1 | First coordinate |
| c2 | Second coordinate |
Returns
A real number indicating the distance in the current map units (e.g., miles).
Example
loc1 = Coord(-120000000, 45000000)
loc2 = Coord(-95000000, 37500000)
dist = GetDistance(loc1, loc2)
