GeoCalc is a utility program provided with the other survey programs. It can be used to convert between coordinate systems, and perform forward and inverse calculations (offsets and distance/azimuth). The user may select geodesic, plane or rhumb line methods.

All survey programs access the same library of coordinate systems, containing over 600 coordinate systems referred to more than 360 datums. The library also includes known coordinates from trusted sources that can be used to verify parameters.
