随着航磁测量复盖的面积日益增大,以及汇编有显著时间差异的相邻测量资料的要求在增加,因而对区域场划分的地磁模式的使用也在增加。事实上,当今儿乎没有航磁承包工作是不采取消除国际地磁标准场(IG-RF)的一些措施。但是,正如一些出版物指出的:这种国际地磁标准场(IGRF)作为应用来讲,远远是不够理想的,尽管有令人尊 With the increasing coverage of aeromagnetic surveys and the need to compile adjacent measurements with significant time differences, the use of geomagnetic models for regional demarcation is also increasing. In fact, there is almost no aeromagnetic contract today that does not take some measures to eliminate the International Geomagnetic Standard Field (IG-RF). However, as some publications point out: this International Geomagnetic Standard Field (IGRF) is far from ideal for applications, although it is respectable
