python - 使用 python geocoder 进行反向地理编码

Question

我正在尝试使用 python 和模块地理编码器进行反向地理编码

我构建了这个脚本

#!/Users/admin/anaconda/bin/python

import geocoder
import unicodecsv
import logging


with open('locs2.csv', 'rb') as f:
    reader = unicodecsv.DictReader(f, encoding='iso-8859-1')
    for line in reader:
        lat = line['lat']
        lon = line['lon']
        g = geocoder.google(['lat','lon'], method=reverse)
        if g.ok:
          g.postal
          logging.info('Geocoding SUCCESS: ' + address)
        else:
          logging.warning('Geocoding ERROR: ' + address)

根据文档 here ，我们可以反过来。但是，当我运行脚本时，出现此错误 NameError: name 'reverse' is not defined

为什么？

TIA

这是我文件中的示例

lat, lon
48.7082,2.2797
48.7577,2.2188
47.8333,2.2500
48.9833,1.7333
47.9333,1.9181
46.2735,4.2586

**编辑**:我对脚本做了一些修改(见下文)，但出现了这个错误

WARNING:root:Geocoding ERROR:

修改后的脚本

#!/Users/admin/anaconda/bin/python

import geocoder
import unicodecsv
import logging

pcode=[] 
lat=[]
lon=[]


with open('locs2.csv', 'rb') as f:
    reader = unicodecsv.DictReader(f, encoding='iso-8859-1')
    for line in reader:
        lat = line['lat']
        lon = line['lon']
        g = geocoder.google([lat,lon], method='reverse')
        if g.ok:
          pcode.extend(g.postal)
          logging.info('Geocoding SUCCESS: '+
str(lat)+','+str(lon)+','+str(pcode))
        else:
          logging.warning('Geocoding ERROR: ' + str(lat)+','+str(lon))

fields= 'lat', 'lon', 'pcode'
rows=zip(lat,lon,pcode) 

with open('/Users/admin/python/myfile.csv', 'wb') as outfile: 
    w =  unicodecsv.writer(outfile, encoding='iso-8859-1') 
    w.writerow(fields) 
    for i in rows: 
        w.writerow(i)

Geocoder 已经取得了长足的进步，最新版本是 1.6.1，有望修复您提到的一些错误。

查看 Reverse Geocoding in Python Geocoder 的最新文档.

import geocoder

g = geocoder.google([45.15, -75.14], method='reverse')
g.city
g.state
g.country
g.postal
