Routing with OSRM

Posted by OpenBrian on 19 May 2017 in English (English)

Setting up OSRM is very easy because it’s using Docker. Here are the steps to take to set up your own router. You can run this locally or on a server. To see this in action check out

OSRM on MappingDC

  1. Install Docker on your machine according to instructions for your operating system.
  2. Download a PBF file for your city from the Mapzen Metro Extracts ( If there is none, sign up and request a new one be built.
  3. Run the backend docker commands from here This takes about 30 minutes as it precomputes some data.
  4. Run the frontend docker commands from here Start the front end with the -e option that specifies the URL to your backend, e.g. http://myhost/osrm-router/
  5. Open ports on your firewall, or set up a proxy in Apache like this:

     # Frontend
     ProxyPass /osrm
     ProxyPassReverse /osrm
     # Backend
     ProxyPass /osrm-router/
     ProxyPassReverse /osrm-router/
  6. Visit http://myhost/osrm-router/

In fact, where the link on this page that says “Provide Feedback on the Diary Feature of OpenStreetMap”?

JOSM tip for squaring buildings

Posted by OpenBrian on 16 May 2014 in English (English)

We all know about Q in JOSM, which will make the angles in a building 90°. But isn’t it annoying when you have one building, you are adding an adjacent building, and when you square the corners it affects the first building? Here’s a pro-tip. When squaring the second building, select it, then add 2 nodes from the first building into your selection. Then hit Q. It will use the first building as a baseline for the second. Notice 2 nodes are highlighted red.
