We used public instances of OSM QC tools such as Atlas and Osmose in addition to internal validation to detect potential map data issues.
The quality checks in the challenges for this project are mainly focused on potential issues such as ‘polygon is not closed,’ ‘spiky buildings’ and ‘polygon has self intersection.’
Please note that some tasks that are worked by the OSM community will show as “already fixed” when in fact they are simply “fixed.” This is due to a processing issue on our end. If the challenge is fully worked, please check back as we will add new data as it becomes available.
Per the “organised editing guidelines,” we will begin working on these tasks in a few weeks.
Here is the project:
