Python Math: Distance between two points using latitude and longitude
27. Geodesic Distance Calculator
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.
