研究了根据设定的角度阈值、拐点个数等条件提取小班拐点坐标的方法,基于ArcGIS的Arcpy和NumPy包技术,使用Python语言实现了小班拐点坐标的批量自动化提取,并能够根据角度阈值等条件实现用户需求的小班拐点坐标的简单智能化提取;通过简单的扩展本程序还可以用于计算已知拐点坐标的情况下,由拐点连接而成的小班面积的快速求算等功能;本方法也能扩展使用在土地变更调查和农地确权工作中的界址点坐标以及拐点坐标的快速标注上。
Based on the ArcGIS Arcpy and NumPy package technology, this paper uses the Python language to realize batch automatic extraction of the inflection point coordinates of small classes, and according to the conditions of the angle threshold and other conditions The method can also be used to calculate the coordinates of a known inflection point by simply extending the program. The method also can quickly calculate the small class area formed by connecting inflection points. The method also Can be extended to use in the land change survey and farmland confirmation work boundary point coordinates and inflection point coordinates on the rapid labeling.
