Visualization of routing results in Google Map.

[Sampson]

Hi all,

I have outputs (as shown in the attachment), containing routes for the vehicles. Each route has a location ID. I later mapped these IDs to the addresses.

I have google map for each route. How do I output them in the same window, each route with a different color, please?

I appreciate any help please.

Thanks.

Sam

You could display your routes with the Google Maps API using the DirectionsService and a DirectionsRenderer (see https://developers.google.com/maps/documentation/javascript/reference/directions).
