I would like make a simple desktop application that can calculate the distance between two cities given by the user. I know that there is no practical purpose for this but I would just like to build it as a programming exercise. I'm having a hard time however with finding the right documentation for this. I would like to do this through an API request and it should be street level routing. Is there anybody that could help me out here by pointing me in the right direction? Thanks in advance. |

You should have a look at the OSM wiki about Routing and its sub-page about online routing Please try each online service listed there, and evaluate yourself whether the user interface comes near your aim, or that you can do some coding for your own. Also pay attention to the age of each routing database ... some are outdated. |
Please EDIT your question and tell us whether you want to have the needed routing data via online download / API request ... or via offline map files on your PC / device ... and then: do you want to know direct lien connection, or street level routing?
