Here we have collected formulas for some common calculations in geodesy.
Here you will find formulas for Gauss-Krüger's projection as well as for conversion between geocentric Cartesian and geodetic coordinates.
- Formulas for Gauss-Krüger's projection (pdf, new window), for transformation between geographic (j , l) and plane (N, E) coordinates.
- Formulas for calculating meridian convergence (pdf, new window). Meridian convergence is the angular difference between "map north" (or coordinate north) – i.e. along the map grid axis – and the true north direction, i.e. the direction of the meridian at the point.
- Formulas for transformation between geocentric Cartesian coordinates (X, Y, Z) and geodetic coordinates (j ,l, h) (pdf, new window).
- Conversion Between latitude and longitude (xlsx, new window) – Excel sheet for conversion between decimal and sexagesimal degrees.
