I'm developing spreadsheet to calculate geographical coordinates (latitude, longitude) to grid coordinates (East, North) and vice versa complete with Grid Convergence and Point Scale) using RedFearns Formula on single zone .
I wrote a spreadsheet to calculate distance and azimuth on ellipsoid sphere using T Vincenty formula. Input coordinates of two locations in lat-lang then the distance and its azimuth will be calculated accordingly.
