Computes the Earth's current or historical magnetic field at a given location using the IGRF model. The magnetic declination computed is useful for compass navigation since it represents the difference between true north and magnetic north. Field inclination and total intensity are also computed which are useful for geophysics purposes. The input latitude and longitude are in decimal degrees and follow the usual conventions of -ve latitude being south and -ve longitude being west. This tool uses the International Geomagnetic Reference Field model (IGRF-11). See http://www.ngdc.noaa.gov/IAGA/vmod/igrf.html for full details. Years from 1900 through to 2015 are supported.
