使用 Geopy 和 Python 进行地理编码 [英] Geocoding using Geopy and Python

问题描述

我正在尝试对包含位置名称和解析出的地址的 CSV 文件进行地理编码，该地址包括地址编号、街道名称、城市、邮政编码、国家/地区.我想通过 Geopy 使用 GEOPY 和 ArcGIS Geocodes.我想创建一个代码，循环遍历我的 5000 多个条目的 csv，并在我的 CSV 的不同列中为我提供纬度和经度.我想通过 Geopy 使用 ArcGIS Geocoding 服务.谁能给我一个代码来开始?谢谢！

I am trying to Geocode a CSV file that contains the name of the location and a parsed out address which includes Address number, Street name, city, zip, country. I want to use GEOPY and ArcGIS Geocodes through Geopy.I wanted to create a code that loops through my csv of 5000+ entries and gives me the latitude and longitude in separate columns in my CSV. I want to use ArcGIS Geocoding service through Geopy. Can anyone provide me with a code to get started? Thanks!

这是我的脚本:

import csv
from geopy.geocoders import ArcGIS


geolocator = ArcGIS()     # here some parameters are needed

with open('C:/Users/v-albaut/Desktop/Test_Geo.csv', 'rb') as csvinput:
    with open('output.csv', 'w') as csvoutput:
        output_fieldnames = ['Name','Address', 'Latitude', 'Longitude']
        writer = csv.DictWriter(csvoutput, delimiter=',', fieldnames=output_fieldnames)
        reader = csv.DictReader(csvinput)

        for row in reader:
            # here you have to replace the dict item by your csv column names
            query = ','.join(str(x) for x in (row['Name'], row['Address']))
            Address, (latitude, longitude) = geolocator.geocode(query)

            # here is the writing section
            output_row = {}
            output_row['Name'] = Name
            output_row['Address'] = Address
            output_row['Latitude'] = Latitude
            output_row['Longitude'] =Longitude
            writer.writerow(output_row)

推荐答案

我一直在使用这个脚本从 .csv 做一些批量地理编码.它要求一列包含您希望对其进行地理编码的完整文本地址，并且一列的标题为UniqueID"，它对 .csv 中的每个项目都有一个唯一标识符.它还将打印出无法进行地理编码的所有地址的列表.它还会快速检查邮政编码是否可能不正确/是否会取消地理编码:

I've been using this script to do some batch-geocoding from .csv. It requires that one column contain the complete text address that you wish to geocode, and that one column be titled 'UniqueID', which has a unique identifier for each item in the .csv. It will also print out a list of any addresses that it failed to geocode. It also does a quick check to see if the zip code might be incorrect/throwing off the geocoding:

def main(path, filename):
# path to where your .csv lives, and the name of the csv.
    import geopy
    from geopy.geocoders import ArcGIS
    import pandas as pd

    Target_Addresses = pd.read_csv(path+'\\'+filename)
    Target_Addresses['Lat'] = np.nan
    Target_Addresses['Long'] = np.nan
    Indexed_Targets = Target_Addresses.set_index('UniqueID')

    geolocator = ArcGIS() #some parameters here
    Fails = []
    for index, row in Indexed_Targets.iterrows():
        Address = row['Address']
        Result = geolocator.geocode(Address)
        if Result == None:
            Result = geolocator.geocode(Address[:-7])
            if Result == None:
                Fails.append[Address]
            else:
                Indexed_Targets.set_value(index, 'Lat', Result.latitude)
                Indexed_Targets.set_value(index, 'Long', Result.longitude)
        else:
            Indexed_Targets.set_value(index, 'Lat', Result.latitude)
            Indexed_Targets.set_value(index, 'Long', Result.longitude)
    for address in Fails:
        print address
    Indexed_Targets.to_csv(filename[:-4]+"_RESULTS.csv")

if __name__ == '__main__':
    main(path, filename) # whatever these are for you...

这将输出一个带有_RESULTS"的新 csv(例如，'addresses.csv' 的输入将输出 'addresses_RESULTS.csv')，其中包含两个新的 'Lat' 和 'Long' 列.

This will output a new csv with "_RESULTS" (e.g., an input of 'addresses.csv' will output 'addresses_RESULTS.csv') with two new columns for 'Lat' and 'Long'.
