Hi everyone,
This is Andrew from the Apple team. I recently created MapRoulette challenges for the road network in Pakistan, such as looking for overlapping roads, disconnected roads and other similar issues. All of the challenges are all posted here in this project: https://maproulette.org/browse/projects/40694
If you haven’t used MapRoulette before it’s a tool to go through OSM issues one by one so you can fix them or mark that they aren’t a problem. I plan to fix a few myself, I hope they are useful. Please let me know if there are any questions or suggestions. Thanks!
