【摘要】 MapGIS制图功能强大,但在绘制地震构造图过程中添加地震震中位置点时却极为繁琐。为此提出一种把记录地震信息的文本文件转换成MapGIS明码文件再生成图形文件,并通过属性连接达到动态标注的方法。按上述方法,以Microsoft VC++6.0为工具,二次开发MapGIS,实现了快速准确绘制地震震中分布图。更多还原

【Abstract】 MapGIS does well in map drawing,but appending dots representing epicenter in seismic tectonic map is an actually tedious work.A method that concludes following steps is presented.Firstly,convert the text file recording earthquake information into the clear text of MapGIS,sencondly,create graphic file from the clear text,finally,connect attribute for dynamically marking.According to the above procedure,taking Microsoft VC++6.0 as the tool,drawing epicentre distribution map based on secondary development of MapGIS can be realized fast and accurately.更多还原
