The conversion between ATS and geographic co-ordinates is based on spatial indices to a very large database of section corners. It is not based on a formula. The conversion between geographic and planimetric co-ordinates is done using public domain algorithms. These are available as C and Fortran source codes from the United States Geological Survey.
