Magnetic Declination Map 2022

But it has now sped up to 9 minutes West each year. The Enhanced Magnetic Model EMM is a research model compiled from satellite marine aeromagnetic and ground magnetic surveys which attempts to include crustal variations in the magnetic field too fine to appear in the World Magnetic Model. Where magnetic north is west of true north the compass needle is deflected to the left. 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.

Magnetic Declination Map 2022. How do you put a north arrow on a map with the UPS grid. The Geographic North Pole is static and is located about 1200 miles north of the Magnetic Pole. The magnetic declination at a given location also changes over time.

Declination results are typically accurate to 30 minutes of arc but environmental factors can cause magnetic field. Magnetic declination 1992 varies from 1605 easterly at centre of west edge to 1403 easterly at centre of east edge. Where magnetic north is east of true north the.

It covers map reading terrain association shooting and following an azimuth back azimuths intersection resection baselines magnetic declination map grids and using a map with a GPS. On a global scale this causes vast geographically irregular and ever-shifting variations in the magnetic declination. Calculated from the IGRF.
