基于AutoCAD实测地质剖面数字成图关键技术

THE KEY TECHNOLOGY FOR DIGITAL MAPPING OF MEASURED GEOLOGICAL PROFILE BASED ON AutoCAD

利用成熟绘图工具AutoCAD提供的二次开发接口作为图件输出平台,以EXCEL表格形式整理输入数据及导出计算结果,以Microsoft Visual Studio.NET为开发语言,开发出了具有自动绘制实测地质剖面图、导线平面图功能的"实测地质剖面成图系统"。以西藏某矿普查地质剖面图绘制为例,对该系统绘制的图件准确性及精度进行了验证,满足了地质剖面图、导线平面图的制作的相关要求。

The measured geological profile map and traverse map constitute an important part of the regional geological map and are used to reflect the underground structures and profile features.In addition,they are the basic maps in geological work.As the maps were drawn by hand in the past,they were not only inefficient but also not easy to preserve and update.The authors used the secondary development interface offered by the sophisticated graphics tools for AutoCAD as the map output stage,the format of EXCEL as the import data and the export of the result,and the Microsoft Visual Studio NET as the development of language to develop a Measured Geological Profile Mapping System which can automatically draw the measured Geological Profile Map and the Traverse Map.With the mapping of the geological survey section in Tibet as an example,this paper has verified the accuracy of the map and the precision of the system.It is shown that the map can meet the requirements for drawing Geological Profile Map and Traverse Map at a variety of scales.
