Geodetic Calculator is an application which performs geodetic computations based on an in-built, extensible copy of the EPSG Geodetic Parameter Dataset

The application includes a copy of the EPSG database and allows user defined datums, coordinate operations and coordinate reference systems to be defined. All geodetic parameters can be viewed, printed or emailed. The system also supports concatenated operations to allow for multistep operations to be computed.

The calculator converts coordinates between two Coordinate Reference Systems and implements the following Coordinate Operation Methods

- Albers Equal Area, American Polyconic, Cassini-Soldner, Coordinate Frame Rotation, Geocentric translations, Geographic/geocentric conversions, Geographic2D with Height Offsets, Hotine Oblique Mercator (variant A+B), Lambert Azimuthal Equal Area, Lambert Conic Conformal (1SP+2SP), Longitude rotation,Mercator (variant A+B), Molodensky-Badekas, NADCON, New Zealand Map Grid, NTv2, Oblique Stereographic, P6 Seismic bin grid transformation, Polar Stereographic (variant A+B+C), Position Vector transformation, Reversible polynomial of degree 4,Transverse Mercator, Transverse Mercator (South Orientated), Vertical Offset.

The calculator includes data files for ConUS and Alaska NADCON conversions, and OSTN02 via NTv2

The calculator also includes a utility to convert and output the current position

The application is fully GIGS tested.
