This particular data set is for the declination of the Earth's magnetic field. The charts are based on the 10th generation International Geomagnetic Reference Field (IGRF-10) main model for 2005 and secular change model for 2005-2010. The IGRF is referenced to the World Geodetic System 1984 ellipsoid. Purpose: This map is intended to show the Earth's main magnetic field and its annual rate of change (secular variation) based on the 10th generation International Geomagnetic Reference Field (IGRF-10). The IGRF is a mathematical model of the Earth's main magnetic field and its secular variation based upon data from magnetic observatories and satellite magnetic missions.

The accuracy of any magnetic field component attribute is dependent on the model's ability to calculate the Earth's magnetic field at any location on Earth. Logical_Consistency_Report: Polygon and chain-node topology are present. Completeness_Report: A circular void of diameter 0.75 degrees was created around the north and south magnetic poles to avoid any problems that these singularities present when calculating and contouring the magnetic field near these locations. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The location of features is based on a mathematical model of the Earth's magnetic field. The location of each point is considered to be correct within the confines of computer accuracy. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The data are computed at mean sea level based on the mathematical model of the Earth's magnetic field. Lineage: Process_Step: Process_Description: The associated declination, based on the 10th generation International Geomagnetic Reference Field, was calculated for a grid of points, having a latitude and longitude spacing of 0.1 degrees. The data were imported into a grid and contoured using ArcGIS. The desired contours for the map were selected and polygon and arc topology were ascertained as well as appropriate feature attributes.
