How To Get Latitude & Longitude with python

Question

I am trying to retrieve the longitude & latitude of a physical address ,through the below script .But I am getting the error. I have already installed googlemaps . kindly reply Thanks In Advance

#!/usr/bin/env python
import urllib,urllib2


"""This Programs Fetch The Address"""

from googlemaps import GoogleMaps


address='Mahatma Gandhi Rd, Shivaji Nagar, Bangalore, KA 560001'

add=GoogleMaps().address_to_latlng(address)
print add

Output:

Solution 1

googlemaps package you are using is not an official one and does not use google maps API v3 which is the latest one from google.

You can use google's geocode REST api to fetch coordinates from address. Here's an example.

import requests

response = requests.get('https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA')

resp_json_payload = response.json()

print(resp_json_payload['results'][0]['geometry']['location'])

Solution 2

For a Python script that does not require an API key nor external libraries you can query the Nominatim service which in turn queries the Open Street Map database.

For more information on how to use it see https://nominatim.org/release-docs/develop/api/Search/

A simple example is below:

import requests
import urllib.parse

address = 'Shivaji Nagar, Bangalore, KA 560001'
url = 'https://nominatim.openstreetmap.org/search/' + urllib.parse.quote(address) +'?format=json'

response = requests.get(url).json()
print(response[0]["lat"])
print(response[0]["lon"])

Solution 3

Try this code:

from geopy.geocoders import Nominatim
geolocator = Nominatim(user_agent="my_user_agent")
city ="London"
country ="Uk"
loc = geolocator.geocode(city+','+ country)
print("latitude is :-" ,loc.latitude,"\nlongtitude is:-" ,loc.longitude)

Simplest way to get Latitude and Longitude using google api, Python and Django.

# Simplest way to get the lat, long of any address.

# Using Python requests and the Google Maps Geocoding API.

        import requests

        GOOGLE_MAPS_API_URL = 'http://maps.googleapis.com/maps/api/geocode/json'

        params = {
            'address': 'oshiwara industerial center goregaon west mumbai',
            'sensor': 'false',
            'region': 'india'
        }

        # Do the request and get the response data
        req = requests.get(GOOGLE_MAPS_API_URL, params=params)
        res = req.json()

        # Use the first result
        result = res['results'][0]

        geodata = dict()
        geodata['lat'] = result['geometry']['location']['lat']
        geodata['lng'] = result['geometry']['location']['lng']
        geodata['address'] = result['formatted_address']

    print('{address}. (lat, lng) = ({lat}, {lng})'.format(**geodata))

# Result => Link Rd, Best Nagar, Goregaon West, Mumbai, Maharashtra 400104, India. (lat, lng) = (19.1528967, 72.8371262)

Hello here is the one I use most time to get latitude and longitude using physical adress. NB: Pleas fill NaN with empty. df.adress.fillna('')

from geopy.exc import GeocoderTimedOut
# You define col corresponding to adress, it can be one
col_addr = ['street','postcode','town']
geocode = geopy.geocoders.BANFrance().geocode  

def geopoints(row):
    search=""
    for x in col_addr:
        search = search + str(row[x]) +' '

    if search is not None:
        print(row.name+1,end="\r")
        try:
            search_location = geocode(search, timeout=5)
            return search_location.latitude,search_location.longitude
        except (AttributeError, GeocoderTimedOut):
            print("Got an error on index : ",row.name)
            return 0,0


print("Number adress to located /",len(df),":")
df['latitude'],df['longitude'] = zip(*df.apply(geopoints, axis=1))

NB: I use BANFrance() as API, you can find other API here Geocoders.

You probably need to set the API key. Like this GoogleMaps(api_key). Take a look at the documentation here py-googlemaps.sourceforge.net

I tried but even then I am getting the same error

[Doing Things Occasionally]

Would this be in your views or in models? Also, if I wanted to store the lat and long in a field how would I do that?

[edesz]

This answer does require an API key.

[Christoph Lösch]

this also needs an api-key which must be set in params like 'key': 'AIza...'

[89f3a1c]

Why would you need Django?

[Mostafa Ghadimi]

It doesn't support utf-8 characters. It's just suitable for latin. Is there any way to make that work for utf-8?

[Wsaitama]

Moreover, it's very easy to use it

[Tommy Lees]

is the API key free or does it cost ?

[saran3h]

As far as i know, this needs a key to work and is chargeable. I wish there was a free solution.

[Santiago]

Would you give a little explanation of how it works?

[Hamish Anderson]

See answers below for a free solution without an api key.

[Prateek]

If you have an API key, add it in the end of the URL like this response = requests.get('https://maps.googleapis.com/maps/api/geocode/j‌​son?address=1600+Amp‌​hitheatre+Parkway,+M‌​ountain+View,+CA&key‌​=<YOUR_KEY>')

[naaman]

Read up on the Usage Policy for this API before selecting the Nominatim/OSM API: operations.osmfoundation.org/policies/nominatim

[x0xRumbleLorex0x]

Just a warning for those who use this snippet, it's doesn't always produce a response. Just so I can save you guys some time.

[Mudit Bhatia]

You have no idea how helpful is this... Thanks...

[Frank Jimenez]

This doesn't work great with normal locations, I've tried with a list of addresses and get a fair amount of NoneType.
