摘　　要：航磁系列图编制的主要内容是将历年航磁测量成果重新整理、拼接,形成航磁基础图件,经过化极处理后,制作上延、剩余、导数等图件供用户使用。笔者就编图工作的几个技术关键问题进行了探讨。The compilation of the aeromagnetic series maps lies in the re-arrangement and collage of aeromagnetic survey results obtained in past years to formulate the basic aeromagnetic maps. Through reduction to the pole, such maps as the upward extension map, the residual magnetic map and the derivative map can be compiled for users. This paper deals with some key technical problems in map compilation.
