<<The map site uses the same routing engine, so the answer must be that you're not sending the same request as the site?
Did you try using the browsers build in developer tools to check the request the site is sending? Kind regards, Emil Tin IT- and Process Specialist Traffic Design >> Emil Good to know it is the same. Yes I used the FF web console to see what was going on. The call being made from the map website is as follows taken from the FF web developer screen: Request URL: http://router.project-osrm.org/viaroute?z=14&output=json&jsonp=OSRM.JSONP.callbacks.redraw&loc=51.534750,-0.135230&loc=51.502874,-0.119249&instructions=true Request Method: GET Status Code: HTTP/1.1 200 OK This produces a drwn route on the map The url I send via my python script is as follows: URL = ' http://router.project-osrm.org/viaroute?z=14&loc=51.502874,-0.119249&loc=51.534750,-0.135230&instructions=true ' The urls are not identical but they are both targetting the same routing site. If I am doing something wrong then I am keen to know so I can correct what I am doing. If anyone can spot the problem I would be very grateful. Thanks John
