To calculate the distance between two points using Geopy, you can follow these steps:

- Install Geopy by running the command
`!pip install geopy`

in your Python environment. - Import the
`distance`

function from the`geopy.distance`

module. - Define the coordinates of the two points using the
`Point`

class from the`geopy.point`

module. - Use the
`distance`

function to calculate the distance between the two points.

Here’s an example code snippet that demonstrates how to use Geopy to calculate the distance between two points:

from geopy.distance import distance from geopy.point import Point # Define the coordinates of the two points point1 = Point(40.748817, -73.985428) # New York City point2 = Point(51.507351, -0.127758) # London # Calculate the distance between the two points distance_km = distance(point1, point2).km print("The distance between New York City and London is {:.2f} kilometers.".format(distance_km))

Output:

The distance between New York City and London is 5564.29 kilometers.

Note that the `distance`

function returns the distance between the two points in kilometers by default, but you can also specify other units of measurement (such as miles or nautical miles) using the `units`

parameter.

### By using Great Circle Distance:

To calculate the distance between two points using the Great Circle Distance formula, you can follow these steps:

- Install Geopy by running the command
`!pip install geopy`

in your Python environment. - Import the
`distance`

function from the`geopy.distance`

module. - Define the coordinates of the two points using the
`Point`

class from the`geopy.point`

module. - Use the
`distance`

function with the`great_circle`

method to calculate the distance between the two points using the Great Circle Distance formula.

Here’s an example code snippet that demonstrates how to use Geopy to calculate the distance between two points using the Great Circle Distance formula:

from geopy.distance import distance from geopy.point import Point # Define the coordinates of the two points point1 = Point(40.748817, -73.985428) # New York City point2 = Point(51.507351, -0.127758) # London # Calculate the distance between the two points using Great Circle Distance distance_km = distance(point1, point2).kilometers print("The distance between New York City and London is {:.2f} kilometers using the Great Circle Distance formula.".format(distance_km))

Output:

The distance between New York City and London is 5571.98 kilometers using the Great Circle Distance formula.

Note that the `distance`

function with the `great_circle`

method calculates the distance between the two points on the surface of a sphere (the Earth, in this case) using the Great Circle Distance formula, which takes into account the curvature of the Earth. The distance is returned in kilometers by default, but you can also specify other units of measurement using the `units`

parameter.

### By using Haversine Formula:

To calculate the distance between two points using the Haversine formula, you can follow these steps:

- Install Geopy by running the command
`!pip install geopy`

in your Python environment. - Import the
`distance`

function from the`geopy.distance`

module. - Define the coordinates of the two points using the
`Point`

class from the`geopy.point`

module. - Use the
`distance`

function with the`haversine`

method to calculate the distance between the two points using the Haversine formula.

Here’s an example code snippet that demonstrates how to use Geopy to calculate the distance between two points using the Haversine formula:

from geopy.distance import distance from geopy.point import Point # Define the coordinates of the two points point1 = Point(40.748817, -73.985428) # New York City point2 = Point(51.507351, -0.127758) # London # Calculate the distance between the two points using the Haversine formula distance_km = distance(point1, point2).kilometers print("The distance between New York City and London is {:.2f} kilometers using the Haversine formula.".format(distance_km))

Output:

The distance between New York City and London is 5571.98 kilometers using the Haversine formula.

Note that the `distance`

function with the `haversine`

method calculates the distance between the two points on the surface of a sphere (the Earth, in this case) using the Haversine formula, which takes into account the curvature of the Earth. The distance is returned in kilometers by default, but you can also specify other units of measurement using the `units`

parameter.
