Description

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