Total Intensity Map of Switzerland 1:500000

Geomagnetic maps are the result of measurements of total intensity, declination and inclination. The geomagnetic field is defined by a vector, which isrepresented in terms of its direction and intensity (nT). Because the Earth's magnetic field changes over time, the data in this map always relates to a specific time period. The values can be adapted using correction formulae which have experimentally determined. Paper map: G. Fischer & P.-A. Schnegg, 1979 (explanatory text on the back of the map). Vector map: 2001.
