Contributing to OpenStreetMap

I had a day off on Monday, there were a couple of things I needed to get done and I just needed another day out of the office.

On the Sunday evening while working out what to do with the rest of the day I happened to be looking at the OpenStreetMap site for the area round my flat. I noticed that the latest set of roads for the second phase of the development hadn’t been included yet.

I use data from the OpenStreetMap project on my Garmin Edge 810 cycle computer to provide both maps and routing information (it’s free vs paying Garmin for map packages) so I really appreciate all the work that has gone into this project so I decided to have a look at how to contribute these new roads.

I knew that people tended to upload GPS data in the form of GPX files that then got used to build the maps. The best tool I had to record the GPS data was my Garmin Edge 810 so I decided to have a quick ride round the new roads.

Strava’s preview has dropped a lot of points, but the actual track looked more like this.

As well as using the 810 I put my Garmin Virb Camera on to record a video of the ride. I mainly did this to catch the street name signs so I could name things properly.

Signing up on the OpenStreetMap site was trivial, just fill in a username and email address, then click on the link in the email that was sent to verify the address. Now I had the option to upload the GPX file. From there I followed the instructions here and use the Potlatch 2 editor to overlay my GPX trace on the existing map. I then traced on the extension of Tinning Way and George Raymond Road and added Annealing Way. I need to go back over the video to double check the names of the other new roads so I can add them as well.

OpenStreetMap tiles get regenerated from time to time so after an hour or two my updates became visible to everybody else.

I’ll have to regenerate the maps for my Garmin Edge 810 sometime to see if it now directs me via these new roads when I set off on my next ride.
