摘　　要：航点航迹图是物化探野外调查中质量监控的重要资料,为提高工作效率,利用VC基于MapGIS、Excel、MSXML二次开发,实现了航点航迹图的批量绘制。详细介绍了程序设计中参数存取、GPX文件读取、图形文件创建、坐标转换、点位信息输出等的具体实现。实际工作应用表明,该方法方便、可操作性强、工作效率高,能在野外质量监控中发挥积极的作用。The waypoints tracking map is an important data for the quality control in the field of geophysical and geochemi cal investigation. Waypoints tracking map batch drawing based on secondary development of MapGIS, Excel, MSXML is real ized with VC to improve the efficiency. This paper introduces the realization of the parameter access in detail, including the GPX file reading, the graphic file creation, the coordinate transformation, and the point information output. The practical ap plication shows that the method is convenient, easy to operate, high efficiency, and can play an active role in the field of quality control.
