MapRoulette challenges in South Africa

Hi everyone,

This is Andrew from Apple. I wanted to let everyone know that we just updated the MapRoulette challenges related to road network issues in South Africa with new OSM data.

You can find all of the challenges in this MapRoulette project: and they include things like overly sharp road angles, roads that cross but aren’t connected, roads that aren’t connected to anything, overlapping roads, turn restrictions, roads that are close but not connected to others, and other similar issues. I plan to work on some of them myself too.

If you haven’t used it before, MapRoulette lets you go through potential issues in OSM data one by one and either correct them or indicate they are not a problem. The challenges were created with our Atlas data analysis tool:

If you aren’t sure what challenge to try, sharp angles or crossing roads are probably the easiest but they should all be fairly straightforward.

And if you’re interested in other countries, the full list is here:

Please let me know if you have any suggestions or feedback. Thank you!

Hello everyone,

We just updated the MapRoulette challenges with new OSM data, and also created a couple of new ones for water and coastline issues, where roads or buildings cross the coastlines. The new challenges are posted here:

In addition, thanks for finishing the previous batch of sharp angle, crossing roads and overlapping roads! There are some more in the new batch.
