GeoMag 3.0

The Geographic Magnetic Calculator is a tool to help you determine UTM Coordinates and the Magnetic Declination that correspond to a longitude/latitude location.
GeoMag is freeware and can be downloaded for your personal use and can only be distributed as a stand alone application. Now updated for the lastest geomagnetic epoch parameters, 2010 through 2015.
GeoMag has date entry boxes with up/down arrows that allow the user to change the location and time for which the Earth's magnetic declination is calculated. When the longitude or latitude change,
GeoMag automatically translates the location to UTM easting, northing, zone number and convergence. In reverse, when changes occur in the UTM easting, northing or zone, GeoMag automatically translates the longitude and latitude. In both case, the Earth's magnetic declination is updated.
