从 Google API 检索地理编码并附加到原始 table - python
Retrieve geocodes from Google API and append to original table - python
我正在尝试通过 Google 地理编码 API 检索一堆地址的地理编码，并将它们附加到我的 table 地址。
在花了两天时间浏览互联网后，我找不到任何简单的方法，虽然它不应该那么难。我在解析 json 输出并将其附加到我原来的 table 时遇到了特别的问题。
我在 windows
上使用 python 3.5
我最初从数据库中获取数据，然后将其添加到 python 中的数据框中。但是将它粘贴到这里更容易将其转换为字典并返回数据框：
data_dict={'street': {0: 'ROMULO', 1: 'SAN BARTOLOME', 2: 'GARBI', 3: 'SAN JOSE'},
'concat': {0: '3+ROMULO+CALLE+ALMERIA',
1: '5+SAN BARTOLOME+CALLE+TOLEDO',
2: '48+GARBI+CALLE+CASTELLON',
3: '30+SAN JOSE+CALLE+SANTA CRUZ DE TENERIFE'},
'number': {0: '3', 1: '5', 2: '48', 3: '30'},
'province': {0: 'ALMERIA',
1: 'TOLEDO',
2: 'CASTELLON',
3: 'SANTA CRUZ DE TENERIFE'},
'region': {0: 'ANDALUCIA',
1: 'CASTILLA LA MANCHA',
2: 'COMUNIDAD VALENCIANA',
3: 'CANARIAS'}}
返回数据框：
import pandas as pd
table=pd.DataFrame.from_dict(data_dict)
现在我从 Google 地理编码中检索数据 API:
import requests
import json
key="MyKey"
jsonout=[]
for i in table.loc[:,'concat']:
try:
url="https://maps.googleapis.com/maps/api/geocode/json?address=%s&key=%s" % (i, key)
response = requests.get(url)
jsonf = response.json()
jsonout.append(jsonf)
except Exception:
continue
我得到这个输出：

我最终想要的是带有纬度和经度坐标的原始 table 数据框
(i['results'][0]['geometry']['location']['lat'],
i['results'][0]['geometry']['location']['lng'])
和请求中的 formatted_address。
我使用 this package 进行地理编码，负责解析 JSON 文件。
from geopy.geocoders import GoogleV3
googleGeo = GoogleV3('googleKey')
# create a geocoded list containing geocode objects
geocoded = []
for address in mydata['location']: # assumes mydata is a pandas df
geocoded.append(googleGeo.geocode(address)) # geocode function returns a geocoded object
# append geocoded list to mydata
mydata['geocoded'] = geocoded
# create coordinates column
mydata['coords'] = mydata['geocoded'].apply(lambda x: (x.latitude, x.longitude))
# if you want to split our your lat and long then do
# mydata['lat'] = mydata['geocoded'].apply(lambda x: x.latitude)
# mydata['long'] = mydata['geocoded'].apply(lambda x: x.longitude)
根据您分享的评论，如果您使用的是 Google 的 API 而没有 API 键，那么在每个地理编码之间加入一个随机停顿可能会有所帮助打电话。
from time import sleep
from random import randint
from geopy.geocoders import GoogleV3
googleGeo = GoogleV3()
def geocode(address):
location = googleGeo.geocode(address)
sleep(randint(5,10)) # give the API a break
return location
然后使用此自定义函数进行地理编码
借助我之前的部分，您甚至可以利用多个地图 API 服务。这是我为我的一个项目构建的函数，首先使用 Nominatim 的 API，然后如果 Nominatim 出现 return 错误或返回到 Google 的 API return没什么：
from geopy.geocoders import Nominatim, GoogleV3
from geopy.exc import GeocoderTimedOut, GeocoderAuthenticationFailure
from random import randint
from time import sleep
nomiGeo = Nominatim() # Nominatim geolocator
googleGeo = GoogleV3('myKey') # Google Maps v3 API geolocator
def geocode(address):
"""Geocode an address.
Args:
address (str): the physical address
Returns:
dict: geocoded object
"""
location = None
attempt = 0
useGoogle = False # set to True to use Google only
while (location is None) and (attempt <= 8):
try:
attempt += 1
if useGoogle:
location = googleGeo.geocode(address, timeout=10)
else:
location = nomiGeo.geocode(address, timeout=10)
if location is None:
useGoogle = True
location = googleGeo.geocode(address, timeout=10)
sleep(randint(5, 10)) # Give the API a break
except GeocoderAuthenticationFailure:
print 'Error: GeocoderAuthenticationFailure while geocoding {} during attempt #{}'.format(address, attempt)
if attempt % 2 == 0: # switch between services for every attempt
useGoogle = True
else:
useGoogle = False
sleep(60)
except GeocoderTimedOut:
sleep(randint(3, 5)) # Give API a break
print 'Error: GeocoderTimedOut while geocoding {} during attempt #{}'.format(address, attempt)
return location
请注意，我还导入了一些特定于包的异常，因为根据我使用 Nominatim 的经验，它有时会抛出随机错误，这就是我得到的两个。此外，根据我对两个 API 的经验，即使未找到某个地址，Google 似乎也能够插入坐标，而 Nominatim 必须在其数据库中包含该地址才能 return 东西.
我正在尝试通过 Google 地理编码 API 检索一堆地址的地理编码，并将它们附加到我的 table 地址。

我最终想要的是带有纬度和经度坐标的原始 table 数据框
(i['results'][0]['geometry']['location']['lat'],
i['results'][0]['geometry']['location']['lng'])
和请求中的 formatted_address。
我使用 this package 进行地理编码，负责解析 JSON 文件。
from geopy.geocoders import GoogleV3
googleGeo = GoogleV3('googleKey')
# create a geocoded list containing geocode objects
geocoded = []
for address in mydata['location']: # assumes mydata is a pandas df
geocoded.append(googleGeo.geocode(address)) # geocode function returns a geocoded object
# append geocoded list to mydata
mydata['geocoded'] = geocoded
# create coordinates column
mydata['coords'] = mydata['geocoded'].apply(lambda x: (x.latitude, x.longitude))
# if you want to split our your lat and long then do
# mydata['lat'] = mydata['geocoded'].apply(lambda x: x.latitude)
# mydata['long'] = mydata['geocoded'].apply(lambda x: x.longitude)
根据您分享的评论，如果您使用的是 Google 的 API 而没有 API 键，那么在每个地理编码之间加入一个随机停顿可能会有所帮助打电话。
from time import sleep
from random import randint
from geopy.geocoders import GoogleV3
googleGeo = GoogleV3()
def geocode(address):
location = googleGeo.geocode(address)
sleep(randint(5,10)) # give the API a break
return location
然后使用此自定义函数进行地理编码
借助我之前的部分，您甚至可以利用多个地图 API 服务。这是我为我的一个项目构建的函数，首先使用 Nominatim 的 API，然后如果 Nominatim 出现 return 错误或返回到 Google 的 API return没什么：
from geopy.geocoders import Nominatim, GoogleV3
from geopy.exc import GeocoderTimedOut, GeocoderAuthenticationFailure
from random import randint
from time import sleep
nomiGeo = Nominatim() # Nominatim geolocator
googleGeo = GoogleV3('myKey') # Google Maps v3 API geolocator
def geocode(address):
"""Geocode an address.
Args:
address (str): the physical address
Returns:
dict: geocoded object
"""
location = None
attempt = 0
useGoogle = False # set to True to use Google only
while (location is None) and (attempt <= 8):
try:
attempt += 1
if useGoogle:
location = googleGeo.geocode(address, timeout=10)
else:
location = nomiGeo.geocode(address, timeout=10)
if location is None:
useGoogle = True
location = googleGeo.geocode(address, timeout=10)
sleep(randint(5, 10)) # Give the API a break
except GeocoderAuthenticationFailure:
print 'Error: GeocoderAuthenticationFailure while geocoding {} during attempt #{}'.format(address, attempt)
if attempt % 2 == 0: # switch between services for every attempt
useGoogle = True
else:
useGoogle = False
sleep(60)
except GeocoderTimedOut:
sleep(randint(3, 5)) # Give API a break
print 'Error: GeocoderTimedOut while geocoding {} during attempt #{}'.format(address, attempt)
return location
请注意，我还导入了一些特定于包的异常，因为根据我使用 Nominatim 的经验，它有时会抛出随机错误，这就是我得到的两个。此外，根据我对两个 API 的经验，即使未找到某个地址，Google 似乎也能够插入坐标，而 Nominatim 必须在其数据库中包含该地址才能 return 东西.
