How to get geolocation information in Python?

There are a number of Python libraries available that provide geolocation services, especially the geopy module, which enables programmers to geocode and reverse geocode addresses and places. Calculating the distance between two points becomes easier with the geopy package, which also provides distance calculation between two points.

There are several libraries for working with geographic data in Python, including GeoDjango, GeoPandas, and PyProj. These libraries make it easier for programmers to work with geographic data such as points, lines, and polygons, allowing them to design applications that require maps and spatial analysis.

You can use the geopy library in Python to obtain geographic location. The following steps guide yoo to get geolocation in Python -

algorithm

  • In your command prompt or terminal, enter pip install geopy to install the Geopy library.

  • Import the required Geopy library modules. The Nominatim class is used for geocoding, and the Point class is used to represent geographic points.

from geopy.geocoders import Nominatim
from geopy.point import Point
  • Create a Nominatim class object that will enable you to perform geocoding. To specify your program, you can pass in a user-agent string.

  • To geocode an address or location, use the geocode method of the Nominatim class. The location you want to geocode is provided by this method as a string.

grammar

geolocator = Nominatim(user_agent="my_app")
location = geolocator.geocode("1600 Amphitheatre Parkway, Mountain View, CA")
  • A Location object containing detailed information about a geocoded location is the result of the geocode function. The latitude and longitude properties of the Point object provide access to the latitude and longitude coordinates of the location.

grammar

point = Point(location.latitude, location.longitude)

Method 1: Obtain location information by name

The Chinese translation of

Example – 1

is:

Example – 1

Using You can use geopy to extract the coordinates or latitude and longitude of a given location. In order to use coordinates to represent a location, you can use it.

# importing geopy library
from geopy.geocoders import Nominatim

# calling the Nominatim tool
loc = Nominatim(user_agent="Get Prayagraj")

# entering the location name
getLoc = loc.geocode("Civil Lines Prayagraj")

# printing address
print(getLoc.address)

# printing latitude and longitude
print("Latitude = ", getLoc.latitude, "\n")
print("Longitude = ", getLoc.longitude)

Output

Civil Lines Prayagraj , Uttar Pradesh , 211001 , India
Latitude =25.454479
Longitude = 81.8338255

Method 2: Use latitude and longitude to identify location

This method is exactly the same as the one above; the only difference is that we will now use the reverse() method, which receives coordinates (latitude and longitude) as parameters, instead of the geocode function. This method returns the address after receiving the coordinates.

Example – 2

# importing modules
from geopy.geocoders import Nominatim

# calling the nominatim tool
geoLoc = Nominatim(user_agent="GetPrayagraj")

# passing the coordinates
locname = geoLoc.reverse("26.7674446, 81.109758")

# printing the address/location name
print(locname.address)

Output

Vinayak City Centre , Tashkant Marg , Civil Lines , Prayagraj , Uttar Pradesh , 211001 , India

in conclusion

The Google Maps API is one of the most popular and user-friendly ways to obtain geolocation data in Python, but there are other options. We can quickly get the longitude and latitude coordinates of any address by installing the googlemaps library and providing a valid API key. OpenStreetMap API and GeoPy library are other possible options.

Security and flexibility. By following a few simple steps, developers can define custom decorators and apply them to a view to modify its behavior or enforce access control.
