'''Haversine formula - Shortest distance between two points on a sphere

Steps:
    1) Convert lat,long for two points from degrees to radians --> divide by 180/pi == 57.29577951
    2) Earth radius in miles -> 3958.8, Km -> 6371
    3) Formula
        hav(lat2 - lat1) + cos(lat1)*cos(lat2)*hav(long2-long1)
        hav(theta) = sin^2(theta/2) = (1 - cos(theta)) / 2
        Let h = hav(theta)
        d = radius * archav(h) = 2 * radius * arcsin(sqrt(h))

Getting GCP access token from a service account key

Use your service account's key JSON file to get an access token to call Google APIs.

Good for seeing how things work, including the creation of JWT token.

To create a JWT token, you can replace create-jwt-token.sh script with tools like step.

If you just want to get an access token for a service account,
