geopandas 写shp

要使用geopandas写入shp文件，需要执行以下步骤：

1.导入geopandas库和其他必要的库：

import geopandas as gpd
from shapely.geometry import Point

2.创建空的GeoDataFrame对象：

crs = {'init': 'epsg:4326'}
gdf = gpd.GeoDataFrame(crs=crs)

3.添加数据到GeoDataFrame对象：

gdf['id'] = [1, 2, 3]
gdf['name'] = ['New York', 'Los Angeles', 'Chicago']
gdf['geometry'] = [Point(-74.0059, 40.7128), Point(-118.2437, 34.0522), Point(-87.6298, 41.8781)]

4.将GeoDataFrame对象写入shp文件：

gdf.to_file('cities.shp', driver='ESRI Shapefile')

完整的代码示例如下：

import geopandas as gpd
from shapely.geometry import Point

crs = {'init': 'epsg:4326'}
gdf = gpd.GeoDataFrame(crs=crs)

gdf['id'] = [1, 2, 3]
gdf['name'] = ['New York', 'Los Angeles', 'Chicago']
gdf['geometry'] = [Point(-74.0059, 40.7128), Point(-118.2437, 34.0522), Point(-87.6298, 41.8781)]

gdf.to_file('cities.shp', driver='ESRI Shapefile')
