MapGIS在地球物理数据成图中的应用

Application of MapGIS in Geophysical Data Mapping

对MapGIS在成图方面的一般步骤作了探讨和研究,并以某地区地面磁测数据作为基础,详细阐述了MapGIS软件在磁测资料成图中的运用,首先将数据准备为可在MapGIS系统中读入的数据格式,然后充分发挥MapGIS空间分析及图形编辑等子系统的功能,绘制磁测数据图件,为其他类似格式的地球物理数据在MapGIS下成图给出了新的思路和途径。实践证明,该方法切实可行,能使制图过程得到进一步简化。

This paper introduces the general process of mapping based on MapGIS, expounds the application of MapGIS in map making with the surface magnetic data in certain area. At first, data with such format that can be recognized in MapGIS is prepared, and then magnetic data maps making the most of its subsystems such as space analyzing subsystem and graph editing subsystem is drawn. This research provides new ways for application of MapGIS in map making by other geophysical data with similar format. It is proved that the method is available, and simplifies the process of mapping. It will serve the users better as well.
