World Magnetic Model High Resolution 2025
The World Magnetic Model High Resolution is a more detailed, accurate depiction of the geomagnetic field than the World Magnetic Model (WMM) because it has more coefficients (18,210 instead of 336) and more digits (4 instead of 1) in each coefficient. The National Geospatial-Intelligence Agency (NGA) highly recommends that all DoD systems use the WMMHR instead of the WMM.
