The utilities and method described in this document are based on the principle of minimizing the tie line and traverse line intersection differences. A Geosoft intersection database is used as the input source to TIELEV.GX which applies a low-pass filter to the mis-tied values along the tie lines. The GX, LOADLEV.GX, then loads the levelling corrections to the tie lines and traverse lines into the main database"--Abstract, page 2. Magnetic fields Computer programs.
