The Magnetic Field Properties Calculator will computes the estimated values of Earth's magnetic field(declination, inclination,
vertical component, northerly component, easterly component, horizontal intensity, or total intensity), for a specific location,
elevation and date or range of dates based on the current International Geomagnetic Reference Field (IGRF). The calculated
result is a grid that contains the calculated component and the annual change of the component over the geographical area
specified. WDeclination is calculated using the current World Magnetic Model (WMM) or International Geomagnetic Reference
Field (IGRF) model. While results are typically accurate to 30 minutes of arc, users should be aware that several environmental
factors can cause disturbances in the magnetic field.

purpose:
The purpose of the calculators is to deliver trusted magnetic field values - past, present, and near future - to aid the public
as well as the scientific community in proper navigation, positioning, and other operational and research magnetic field scenarios.

source description
The IGRF is the product of a collaborative effort between magnetic field modellers and the institutes involved in collecting
and disseminating magnetic field data from satellites and from observatories and surveys around the world. The IGRF is a series
of mathematical models of the Earth's main field and its annual rate of change (secular variation).

Description The International Association of Geomagnetism and Aeronomy (IAGA) has released the 11th Generation International Geomagnetic
Reference Field, which is the latest version of a standard mathematical description of the Earth's main magnetic field that
is used widely in studies of the Earth's deep interior, its crust and its ionosphere and magnetosphere.
specification > The Magnetic Field Properties Grid Calculator creates an XML document which indicates the declination, inclination, horizontal
intensity, northerly component, easterly component, vertical component, or total field at the geographical range queried and
reports the annual change for the parameter specified.
