Python code for reverse Geo-coding using Google API

Question

I am getting the geo-data in a json file (geo.json) which has the following structure

 {"userId":"Geo-data","data":{"mocked":false,"timestamp":1548173963281,"coords":{"speed":0,"heading":0,"accuracy":20.20400047302246,"longitude":88.4048656,"altitude":0,"latitude":22.5757344}}}

All I want is to print the place details corresponding to above data and if possible to show it on MAP also.I have tried the following code with geopy

from geopy.geocoders import Nominatim
geolocator = Nominatim()
location = geolocator.reverse("22.5757344, 88.4048656")
print(location.address)
print((location.latitude, location.longitude))

But the location I am getting is not very accurate. Whereas the same coordinates give good results in https://www.latlong.net/Show-Latitude-Longitude.html I also have a Google API key. However, what ever references I found so far are almost like a project themselves and a overkill for a beginner like me. The geopy code was fine but the location accuracy is very poor. Please help.

P.S I have tried geocoder also as

import geocoder
g = geocoder.google([45.15, -75.14], method='reverse')
print(g.city)
print(g.state)
print(g.state_long)
print(g.country)
print(g.country_long)

However it is printing 'None' in all the cases.

Don't know why someone has marked it negative. It is not a duplicate and I have tried to explain everything I tried so that someone can help. How else am I suppose to ask? — Bukaida

You could consider to switch from OpenStreetMap Nominatim provider to Google Geocoding. Then, the following example seems returns the address you expect it to:

from geopy.geocoders import GoogleV3

geolocator = GoogleV3(api_key=google_key)
locations = geolocator.reverse("22.5757344, 88.4048656")
if locations:
    print(locations[0].address)  # select first location

Result

R-1, GA Block, Sector III, Salt Lake City, Kolkata, West Bengal 700106, India

Thanks, works perfectly in command line. Anyway to show the same on Map? I have unrestricted Test API.

with the latest geopy library ( 2.2.0 ) the geolocator.reverse() call defaults the exactly_one=True argument. Thus the code should be modified to location = geolocator.reverse("22.5757344, 88.4048656") if location: location.address

You can try a Python Client for Google Maps Services library that can be found at

https://github.com/googlemaps/google-maps-services-python

This is a wrapper library for Google Maps API web service requests developed by Googlers. The code snapshot is the following

import googlemaps
gmaps = googlemaps.Client(key='Add Your Key here')

# Look up an address with reverse geocoding
reverse_geocode_result = gmaps.reverse_geocode((22.5757344, 88.4048656))

This code returns address R-1, GA Block, Sector III, Salt Lake City, Kolkata, West Bengal 700106, India similar to the result that you can see in Geocoder tool:

https://developers-dot-devsite-v2-prod.appspot.com/maps/documentation/utils/geocoder/#q%3D22.575734%252C88.404866

For further details have a look at the documentation in github.

I hope this helps!

It is showing a screen full of information as my API key is unrestricted. I have seen the Github before asking help here, but it was a overkill for a noob like me.
