Abstract:

The study of geomagnetic fields is one of the earliest studies in the field of geosciences. At present, measurement of the geomagnetic field is concerned with answering the fundamental questions about the Earth’s deep interior, mantel conductivity, structure and the thermo-mechanical properties of its crust, its lithosphere and the near-Earth environment. This paper presents a method that addresses the problem of site selection for a new geomagnetic field observatory in the Republic of Slovenia. The method relies on a multi-stage multi-criteria decision model. The Geographic Information System (GIS) was used as a platform enabling the management of the criteriadata, spatial analysis, cartographic modelling and production of map layers. Feasible areas were produced using a Boolean overlay, followed by the application of the multi-criteria evaluation (MCE) method on feasible areas to select the best one. Furthermore, preliminary measurements of geomagnetic fields were observed, including the measurement of the total-intensity gradient of the magnetic field vector, the measurement of the geomagnetic field at a base-point, as well as the absolute and the three component measurements of the geomagnetic field.
