[Talk-ng] MapRoulette challenges in Nigeria - help fix road data

[Andrew Wiseman]

Hi everyone,

This is Andrew from the Apple team. I recently updated MapRoulette challenges for the road network in Nigeria, such as looking for overlapping roads, disconnected roads and other similar issues. I put them all in a project so you can see the latest ones here: https://maproulette.org/browse/projects/38975 <https://maproulette.org/browse/projects/38975>

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!

Andrew

We recently used our Atlas data analysis tool (https://github.com/osmlab/atlas <https://github.com/osmlab/atlas>) to look at a few types of potential issues related to roads and routing, such as roads that have overly sharp angles, roads that cross but don't connect, routing problems, turn restrictions, places where navigation is impossible due to missing connections or potentially incorrect one-way roads, and other similar issues.

I wanted to let you know they are available in case others wanted to try fixing some of them — I also plan to go through some of them myself.
