Google Maps essentially uses two Graph algorithms — Dijkstra's algorithm and A* algorithm, to calculate the shortest distance from point A ( Source) to point B ( destination). A graph data structure is essentially a collection of nodes that are defined by edges and vertices.

Google Maps uses a complex algorithm to recommend routes based on various factors, including: Distance and Time: Google Maps considers the distance and estimated travel time for each possible route. It aims to provide the shortest or fastest route depending on user preferences.

On your computer, open Google Maps. Right-click the place or area on the map. This will open a pop-up window. You can find your latitude and longitude in decimal format at the top.
