摘要
在测绘地理信息数据整理领域,查找并处理多边形的尖锐内角是一项日常性的数据处理任务。本文探讨了一套在ArcGIS平台下的快速探测多边形锐角的方法,采用ArcGIS内置的Python语言实现了任意尺寸角度的自动检测,可方便快捷地查找符合一定角度阈值的锐角,可有效减轻内业人员工作量,提高工作效率。
In the field of surveying and mapping geographic information data processing,it is a daily data processing task to find and process the acute inner angle of polygon.This paper discusses a set of methods to detect polygon acute angle quickly on the platform of ArcGIS.The python language built in ArcGIS is used to realize the automatic detection function of any size and angle.It can easily and quickly find the acute angle in line with a certain angle,which can effectively reduce the workload of office workers and improve work efficiency.
