Declination Map
Map with isogons (lines with the same magnetic declination values), which describe the difference between the orientation of the compass needle and true north.

The Earth´s magnetic field is subject to natural fluctuations on different time scales, which can affect navigation systems, communication systems and other technological applications over time.
The annual measurement of the secular points enables the declination map to be updated regularly. The result is an up-to-date map with isogons (lines with the same magnetic declination values), which describe the difference between the orientation of the compass needle and true north.
