Magnetic declination (variation) calculator based on the IGRF magnetic field model. Estimates magnetic delination world-wide from 1900 - present.
2 lip 2022 · Use the tool below to compute values for the geomagnetic field and secular variation for a given set of coordinates and date. This calculator uses the World Magnetic Model as released in Dec 2019. Choose the geodetic latitude and longitude either by entering the coordinates into the form below (decimal degrees may be entered into the 'degrees' ...
The difference between true north and magnetic north is called magnetic declination or magnetic variation. Some sources also erroneously refer to it as magnetic deviation. It's essential to take this phenomenon into account when navigating with a compass.
The angle between magnetic north and true north is called magnetic declination. Many people believe that a compass needle points at the North Magnetic Pole. This is not true; if you follow your compass needle you will eventually arrive at the North Magnetic Pole, but not by the most direct route.
This free utility will generate a PNG or SVG file representing a properly formatted declination diagram for a specific map. Background. In cartography, a declination diagram is used to provide a graphic representation of the variations between true north, grid north, and magnetic north on a map.
Maps of Magnetic Elements from the WMM2020. Contour maps were created for each of the seven magnetic elements (D, I, H, X, Y, Z, and F) and for their secular variation (rate of change).
