An overview of the Magnetic toolset

The tools in the Magnetic toolset allow you to calculate magnetic field values, such as declination and horizontal strength, and store them in your data or use them to generate isolines on maps. The magnetic field values are calculated using the World Magnetic Model.



Magnetic Calculator

Computes the magnetic field at point locations for a date you specify. You must provide an altitude or specify a field of type double in your data that contains altitude data. The date must be between 1/1/2005 and 12/31/2014. The magnetic value is calculated using the World Magnetic Model.

Magnetic Isolines

Creates isomagnetic lines in an extent for a date between 1/1/2005 and 12/31/2014 based on the World Magnetic Model. The tool uses a magnetic field parameter and line generation method to create a new polyline feature class.
