This is Andrew from Apple’s Maps team. We did some mapping on road issues a while ago in Ukraine (https://github.com/osmlab/appledata/issues/19) and recently used our Atlas data analysis tool (https://github.com/osmlab/atlas) to look for a few types of potential issues, such as roads with sharp angles, overlapping roads, buildings that intersect roads, and highway link roads that don’t match the classification of nearby roads.
I posted the results of those checks on MapRoulette, a tool that lets you go through potential issues one by one and either correct them or indicate they are not a problem. 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.
In MapRoulette you can either pick a random task to fix or click on a specific one. If you want to do tasks around a certain location, such as somewhere you are familiar with, you can click “more options” then “load tasks by proximity.”
The checks are:
- Sharp angle roads: https://maproulette.org/mr3/challenge/3531
- Building-road intersections: https://maproulette.org/mr3/challenge/3529
- Overlapping ways (usually duplicated roads): https://maproulette.org/mr3/challenge/3530/
- Road link check: https://maproulette.org/mr3/challenge/3532
Let me know if you have any questions or feedback.
