摘要
现阶段,为了满足工程施工需要,往往需要提取地形图纸中多段线的拐点坐标。传统的坐标提取方法主要有两种:一种是在AutoCAD中利用显示图形数据信息命令LIST和指示点命令ID进行坐标提取;另一种是采用AutoCAD编程语言或者专业软件进行坐标提取。但前者效率低,容易出错,而后者对作业人员的编程能力要求较高,不易实现。为了解决上述问题,本文提出了一种基于ArcGIS批量提取坐标的方法,并且通过实例验证了该方法的有效性。结果表明,该方法有效解决了坐标批量提取问题,减少了人为错误,极大地提高了工作效率。
At present,in order to meet the needs of Engineering construction,it is often necessary to extract the inflection point coordinates of multi-segment lines in topographic drawings.There are two traditional methods of coordinate extraction:one is to use LIST command and ID command to display graphical data information to extract coordinates in AutoCAD;the other is to use AutoCAD programming language or professional software to extract coordinates.However,the former is inefficient and error-prone,while the latter requires higher programming ability of operators and is not easy to achieve.In order to solve the above problems,this paper proposed a batch coordinate extraction method based on ArcGIS,and the effectiveness of this method was verified by an example.The results show that the method completely solves the problem of coordinate batch extraction,reduces human errors and greatly improves work efficiency.
