GeoPandas is an open source project to make working with geospatial data in python easier. I have the latitude and longitude coordinates for p1 and p2 and have the p3 - p1 distance in meters and bearing of p1. geopy, which is a Python library working as a client for the most famous geocoding services. But it calculates in meters, so if you want to use miles just multiply distance on 1609. default_user_agent = "my-application". The link above is to the Distance Matrix API, which will help with working out distances between 2 points. 2. Testing my code with : 0° <= bearing of point 2 <= 120° Seems to work fine except for the value 0° as said earlier. I have bearing of two points 115 33' 09" and distance between these two points is 1464. apply (elevation_function, axis=1) # Print output df. It is more accurate than the Haversine and spherical law of cosines methods, as it accounts for the Earth’s ellipsoidal shape. kolkata = (22.
