Raziskave na področju geomagnetizma lahko označimo kot prve raziskave na področju geofizike. Opazovanje geomagnetnega polja je bistvenegapomena za razumevanje temeljnih postopkov v središču Zemlje, ...njeni skorji in bližnji okolici planeta Zemlja. V prispevku je predstavljena metodologija izbire lokacije za postavitev geomagnetnega observatorija na ozemlju Republike Slovenije. Izbira temelji na večstopenjskem in večkriterijskem modelu odločitve.Prvi del je zasnovan v okolju GIS kot postopek analize in vrednotenja prostora ter opredelitve lokacije glede na predhodno postavljena merila. Nadaljnja analiza temelji na metodi utežne vsote, saj moramoupoštevati različne skupine parametrov, ki v končni oceni primernosti lokacije nimajo enakega pomena. Pri zasnovi modela je bil poseben poudarek na izločitvi območij, kjer je mogoče pričakovati višjeravni elektromagnetnega šuma. Na potencialno primernih območjih so bili opravljeni terenski ogledi in preliminarne meritve homogenosti gradienta totalne intenzitete magnetnega polja ter absolutne, bazne intrikomponentne meritve geomagnetnega polja. ; 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 observatoryin 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 criteria data, 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 basepoint, as well as the absolute and the three componentmeasurements of the geomagnetic field.
