GeoCalc calculates geographical coordinates given a start point distance and heading or calculates the distance and heading between two points. The calculated coordinates can be set as the initial coordinates allowing fast consecutive calculations.

GaoCalc may be used for roadbook off-road racing hiking sailing orienteering geocaching questing treasure hunting hobby flying for education for fun or anyone needing to calculate bearings and distances between coordinates.

Calculations are performed using an accurate ellipsoidal model of the Earth's surface.
