Conversion from Swiss Grid to the WGS84-system provides a conversion tool from the Swiss Grid to the WGS84-system.

The conversion is based on the following material from the Swiss Federal Office of Topography, Wabern:

  • Swiss projection system. Formulae for the conversion of grid coordinates into geographic coordinates and vice versa, 1984
  • Transformation of grid coordinates CH-1903 into WGS-84 coordinates, 1990
  • Addendum to the compilation of formulae for the conversion from WGS84 coordinates into Swiss projection coordinates.

Many thanks for providing this material.
