Computing the travel distance between two points requires a routing engine. A routing engine needs to be run on a server. There are a couple of people who operate such servers and who will let you use them for free, for example the server at http://map.project-osrm.org. That site also contains documentation about how to call the server and get a JSON response (or just switch on your browser's net debugger and see what requests it sends). Be aware however that if you should set up a web site that makes many such routing requests, or even a commercial site of which such routing is an integral part, then you should not use these volunteer run resources, but instead set up your own routing server. The software and the data are free for the taking - but the computing resources need to be paid for by someone! |
