This map layer shows isogonic lines (lines of constant declination of the Earth's magnetic field), derived from the International Geomagnetic Reference Field (IGRF) for the epoch 1995.0. Magnetic declination is the angle between true north and magnetic north (the direction of the magnetic field vector) in the horizontal plane.

This map layer shows isodynamic lines (lines of equal total intensity of the Earth's magnetic field), derived from the International Geomagnetic Reference Field (IGRF) for the epoch 1995.0. Magnetic intensity is the strength of the magnetic field, and is described in terms of a horizontal component and a vertical component. The total field intensity is the strength of the field, not divided into its component parts.

This map layer shows lines of equal annual change (secular variation), in the total field intensity of the Earth's magnetic field, derived from the International Geomagnetic Reference Field (IGRF) for the epoch 1995.0. Magnetic intensity is the strength of the magnetic field, and is described in terms of a horizontal component and a vertical component. The total field intensity is the strength of the field, not divided into its component parts. The change in intensity is measured in nanoTeslas per year.

This map layer shows lines of equal vertical intensity of the Earth's magnetic field, derived from the International Geomagnetic Reference Field (IGRF) for the epoch 1995.0. Magnetic intensity is the strength of the magnetic field, and is described in terms of a horizontal component and a vertical component. Vertical intensity is the vertical strength of the magnetic field.

This map layer shows lines of equal annual change (secular variation) in the vertical component of the total field intensity of the Earth's magnetic field, derived from the International Geomagnetic Reference Field (IGRF) for the epoch 1995.0. Magnetic intensity is the strength of the magnetic field, and is described in terms of a horizontal component and a vertical component. The change in intensity is measured in nanoTeslas per year.

This map layer shows isoporic lines (lines of equal annual change, or secular variation, in the declination of the Earth's magnetic field), derived from the International Geomagnetic Reference Field (IGRF) for the epoch 1995.0. Magnetic declination is the angle between true north and magnetic north (the direction of the magnetic field vector) in the horizontal plane. The change is measured in arc minutes per year.
