Python | Reverse Geocoding to get location on a map using geographic coordinates
  • Last Updated : 31 May, 2020

Reverse geocoding is the process of finding a place or a location address from a given pair of geographic coordinates(latitude and longitude).

Modules needed:

reverse_geocoder: A Python library for offline reverse geocoding.
pprint: A module which helps to "pretty-print" any arbitrary python data structure.

Installation:
The modules can be easily installed using pip.

pip install reverse_geocoder
pip install pprint

Examples:

Input : (36.778259, -119.417931)
Output : 
Loading formatted geocoded file...
[{'admin1': 'California',
  'admin2': 'Fresno County',
  'cc': 'US',
  'lat': '36.72384',
  'lon': '-119.45818',
  'name': 'Minkler'}]
Input : (28.644800, 77.216721)
Output : 
Loading formatted geocoded file...
[{'admin1': 'NCT',
  'admin2': 'New Delhi',
  'cc': 'IN',
  'lat': '28.63576',
  'lon': '77.22445',
  'name': 'New Delhi'}]

    # Coorinates tuple.Can contain more than one pair.
    coordinates =(28.613939, 77.209023)
      
    reverseGeocode(coordinates)

Output:

Loading formatted geocoded file...

  'cc': 'IN',
  'lat': '28.63576',
  'lon': '77.22445',
