I'm trying to improve a workflow that currently involves manually composing a multi-destination driving route in Google Maps. I have the ability to export a KML file containing the points we want via RGDAL. I'm hoping to end up with a navigation route starting at one point in the KML and routing through all other points before returning to the starting point.
Is there a way to generate this route in Google Maps or Google Earth? The workflow currently ends with sharing a Google Maps link with coworkers who can then open the link on their phones and view the navigation directions the Maps app. Is there a straightforward way to generate a route like this, starting with a KML file?
