摘要：Geophisical fields usually are used forpractical purposes as scalar fields. As anexample relief's field, radar's and opticalimages of the Earth surface may beregarded. From other side gravitional andmagnetic fields are vector fields in thenature. In general informative capabilityof vector fields is higher then scalar onefor the reason of some sundry components.However, to realize this advantage isn'talways possible. The reasons are asundeveloped appropriate algorithms andtechnical difficulties. The pecularities ofvector fields are investigated below on theexample of radiothermal vector fields ofthe Earth's covers. The advantages of suchapproach in comparison with "scalar"methods for concrete problems arediscussied
