import geopandas as gpd from sqlalchemy import create_engine from geoalchemy2 import Geometry,WKTElement WKTElement(x.wkt,4326)) 因为GeoDataFrame中默认存的simple features 对象与postgis库中定义的默认simple features对象存在差异,这里需要使用geoalchemy2 包提供的Geometry,geoalchemy2接口将GeoDataFrame转换为postgis库可识别的模式。
你需要导入这几个第三方库: import geopandas as gpd import psycopg2 from sqlalchemy import create_engine from geoalchemy2
geopandas与PostGIS进行交互 为了能在geopandas中与postgresql和PostGIS建立连接,请确保以下3个库已经安装: pip install sqlalchemy, psycopg2, geoalchemy2
PostGIS进行交互 为了能在geopandas中与postgresql和PostGIS建立连接,请确保以下3个库已经安装: pip install sqlalchemy, psycopg2, geoalchemy2
Python-gis数据批量入库: import geopandas as gpd import pandas as pd from sqlalchemy import create_engine from geoalchemy2
下面的示例用[Geoalchemy2](https://geoalchemy-2.readthedocs.io/)库说明了这一点: ```py from geoalchemy2 import Geometry 下面的例子使用了 Geoalchemy2 库说明了这一点: from geoalchemy2 import Geometry from sqlalchemy import Column, Integer
