| Abstract: | This study was conducted to select an appropriate characteristic variable of geomagnetism to match for guidance. First, several critical factors in the selection of the characteristic variable for matching was presented catering to the practical need of the geomagnetic matching, then the selection rules were studied out according to theoretic analyses, finally detailed study and comprehensive analyses were carried out according to the IGRF10 and the WMM2005, and the preparatory selection result for a special area was given. This study can be used as a reference on studies of the preparation of reference maps, the retrieve of real- time maps, the algorithms for matching, and the applications of geomagnetic field resource in other fields. |
