地球法：如何将列几何形状转换为字符串？

Question

我有一个地geopandasdataframe

    geometry                                           idx
0   POLYGON ((-74.25559 40.91553, -74.24559 40.915...   0
1   POLYGON ((-74.25559 40.90553, -74.24559 40.905...   1
2   POLYGON ((-74.25559 40.89553, -74.24559 40.895...   2
3   POLYGON ((-74.25559 40.88553, -74.24559 40.885...   3
4   POLYGON ((-74.25559 40.87553, -74.24559 40.875...   4

Whather

gridDF['geometry'][0]
 <shapely.geometry.polygon.Polygon at 0x7fa4cc6ccc50>

我想将列中的条目转换为字符串。

如果您想一次执行所有行，您可以使用应用。

geometry

Answer 1

我认为您可以使用此功能：

shapely.wkt.dumps

Answer 2

示例：

from shapely import wkt
gridDF['str_geom'] = gridDF.geometry.apply(wkt.dumps)

from shapely import wkt
wkt_string = wkt.dumps(gridDF['geometry'][0])
print(wkt_string)

应该是WKT格式的字符串的几何形状。
