Geodetic

Geodetic is a standalone applicartion which will allow the user to carry out a series of geodetic calculations using either predefined parameters or user input data.
The software was first developed in 1984 to run on a PC running under DOS and has been constantly been redeveloped in line with PC development.
The current version runs under Windows XP and Vista.

Based on the computational routines used with Geodetic Norcom has developed a stand alone DLL that can be incorporated into and third party software developed
in Visual Basic or Visual C++ For more details
