PolygonToLine 示例 2(独立脚本) 以下独立脚本是演示如何在脚本环境中应用PolygonToLine函数的简单示例。 # Name: PolygonToLine_Example2.py# Description: Use PolygonToLine function to convert polygons to lines,# and report how many shared or overlapping boundary lines# were found.# import system modul...
If two polygons share a portion of their boundaries, one output line will be generated representing the shared segment. The line direction will be arbitrary; theLEFT_FIDand theRIGHT_FIDwill be set to the left or right polygon feature IDs accordingly. ...
① 面转线：polygon to line是把面的轮廓线转换为一个线对象；面转点：feature topoint是只把面对象的中心点转换为点要素；面折点转点：featurevertices to points把面的轮廓的所有的折点转化为点。② 线转面：feature to polygon是把闭合线转换为面对象。线转点：feature topoint是把线的中心点转为点。

对比Shapely包:Shapely中有Point、LineString、Polygon、MultiPoint、MultiLineString、MultiPolygon、GeometryCollection,也支持从numpy的array对象创建几何对象。 Point和PointGeometry Point无空间参考信息,通常是一对点坐标,PointGeometry有空参考信息,是一个几何对象。下面的代码演示了 Point 对象如何使用PointGeometry类构造几...
选择world,然后选择Shapefile,就可以下载到一个Polygon格式的世界地图。或者选择geopackage,得到依据国、省、市为三级分类的数据地理数据库格式文件。 打开ArcMap,将文件导入Dataframe,然后我们使用Project命令将文件坐标转换为GCS_WGS_1984坐标。之后在D...
