Python Math: Distance between two points using latitude and longitude

Python Math: Exercise-27 with Solution

Write a Python program to calculate distance between two points using latitude and longitude.

Sample Solution:

Python Code:

from math import radians, sin, cos, acos

print("Input coordinates of two points:")
slat = radians(float(input("Starting latitude: ")))
slon = radians(float(input("Ending longitude: ")))
elat = radians(float(input("Starting latitude: ")))
elon = radians(float(input("Ending longitude: ")))

dist = 6371.01 * acos(sin(slat)*sin(elat) + cos(slat)*cos(elat)*cos(slon - elon))
print("The distance is %.2fkm." % dist)

Sample Output:

Input coordinates of two points:                                                                              
Starting latitude: 23.5                                                                                       
Ending longitude: 67.5                                                                                        
Starting latitude: 25.5                                                                                       
Ending longitude: 69.5                                                                                        
The distance is 300.67km.
