A spherical geometry calculator and navigation aid, aimed at sailors, pilots and navigators on one hand, and airmchair travellers on the other. Spheric will compute distance between points on Earth (including highly accurate geodesic and elliptic arc approximations), cumulative distance for a serias of points, range and bearing, azimuth, midpoint, great arc intersections, distances between great arcs and points, and some more. Various display and input formats (deg, rad, dms) are provided. Data can be saved to, and loaded from, ASCII files, and the program status upon exit is saved to disk, to be loaded on the next run. A Help file is provided.
