如何从wkt MultiPolygon获取坐标

Question

我有一个wkt格式的MultiPolygon列表，我必须从这些点获取坐标。

有人能帮帮我吗？提前感谢

您可以使用修长 Python模块解析WKT几何并提取坐标。

尝试如下：

import shapely.wkt

shapes = [ 'MULTIPOLYGON (((69.0 41.0, 69.0 41.4, 69.4 41.4, 69.4 41.0, 69.0 41.0)), ((59.0 42.0, 59.0 42.4, 59.4 42.4, 59.4 42.0, 59.0 42.0)))' ]

for shape in shapes:
  shapelyObject = shapely.wkt.loads(shape)
  for polygon in shapelyObject:
      coords = list(polygon.exterior.coords)
      print(coords)

输出：

[(69.0, 41.0), (69.0, 41.4), (69.4, 41.4), (69.4, 41.0), (69.0, 41.0)]
[(59.0, 42.0), (59.0, 42.4), (59.4, 42.4), (59.4, 42.0), (59.0, 42.0)]
