Description
Geomagnetic maps are the result of measurements of total intensity, declination and inclination. The declination describes the angle formed between magnetic and geographic north. 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.
