Google provides APIs for 1. Distance Matrix and 2. Direction service
I tried to search about difference between 1 and 2
My task is “When user moves from Source S to Destination D
using some path. We need to show the actual path user has traversed
on Google Map“
What is best way to accomplish it ?
Using 1. Distance Matrix APIs or 2. Direction service
According to Google Maps API picker
You use Directions service for getting directions from origin to destination location using various forms of transport: walking, driving, cycling, public transit. Get a route from point A to point B.
For Distance Matrix it calculate the travel distance and travel time for multiple origins and destinations, optionally specifying various forms of transport: walking, driving, cycling.
For your case, I will suggest Directions service since you don’t need travel time.
I got answer to my question.
Google Maps V2 provides 2 sets of APIs for developers
1. Distance Matrix APIs : this is useful for computing distance(walking/travelling via bycycle,bus), cost of travel, time of travel
But this is not useful for this scenario.
2. Direction Service : this is useful for this scenario.
Through direction service, we can get the path of User on Google Map in Real Time
If we get the path through Distance Matrix, then Google Map returns
the shortest established path between S Source and D
Destination, this is not desirable in this scenario. User may not use
shortest path due to some trafic, personal reasons and Diatance Matrix
API output fails here.
So, I should use Direction Service API which give me real time Output for User location on Google Map
