python - 如何从数据框中的地址列表中查找坐标

问题描述

我正在尝试在我的数据框中为经度和纬度创建 2 列，我想通过使用名为“详细信息”的地址列来查找它们。

我试过从

geopy.extra.rate_limiter import RateLimiter

locator=Nominatim(user_agent="MyGeocoder")

results['location']=results['Details'].apply

results['point']=results['location'].apply(lambda loc:tuple(loc['point']) if loc else None)
results[['latitude', 'longitude',]]=pd.DataFrame(results['point'].tolist(), index=results.index)

但这给出了错误“方法对象不可下标”

我想创建一个循环来获取每个地址的所有坐标

解决方案

尝试这个

import pandas as pd
import geopandas
import geopy
from geopy.geocoders import Nominatim
from geopy.extra.rate_limiter import RateLimiter

locator = Nominatim(user_agent="myGeocoder")
geocode = RateLimiter(locator.geocode, min_delay_seconds=1)

def lat_long(row):
    loc = locator.geocode(row["Details"])
    row["latitude"] = loc.latitude
    row["longitude"] = loc.longitude
    return row

results.apply(lat_long, axis=1)
