Each calculation is for a specific location, elevation and date or range of dates. The calculated result can be obtained from two separate geomagnetic models, the IGRF11 or the WMM2010. Get the Data Access Format(s) Distributor(s) / Contact Info Instructions / Constraints HTML Format Format version: 1 Format specification: The Magnetic Field Calculator creates an HTML pop-up window which indicates the declination, inclination, horizontal intensity, northerly component, easterly component, vertical component, and total field at the location queried and reports the annual change for each parameter. XML Format Format version: 1 Format specification: The Magnetic Field Calculator creates an XML document which indicates the declination, inclination, horizontal intensity, northerly component, easterly component, vertical component, and total field at the location queried and reports the annual change for each parameter. CSV Format Format version: 1 Format specification: The Magnetic Field Calculator creates an Comma Seperated Variable (CSV) file which indicates the declination, inclination, horizontal intensity, northerly component, easterly component, vertical component, and total field at the location queried and reports the annual change for each parameter.
