Visualization of Earth main magnetic field maps on a spherical display

Geophysical Center RAS, Moscow, Russia

Abstract

Thematic maps of the Earth Main Magnetic Field (EMMF) components compiled on various magnetic epochs and based on historical and instrumental observations are an effective tool for representation and analysis of EMMF and its temporal evolution. Such maps are published both as separate cartographic documents and selected map collections – atlases. The main disadvantage of cartographic editions published in the form of paper maps is their lack of visual representation. Modern GIS representation technologies are highly efficient for the visual analysis of cartographic documents. GIS-technologies are common in demonstration systems based on up-to-date visualization means. One of the most advanced instruments for visualization and representation of georeferenced data are digital projection systems with a spherical display.
