I have collected data about advice relationships among few hundreds primary care physicians whose offices are distributed across a territory. Based on the addresses of the physician offices, which I have, I would like to create also a geographical distance network, where the generic cell "i" shows the miles / kilometres between the generic pair of physicians.
I know a way to do this manually (pair by pair) on Google Maps. Is there an automatic (and hopefully free of charge) way to do this?
Thanks a lot
