We used public instances of OSM QC tools such as Atlas and Osmose in addition to internal validation to detect potential map data issues in Eastern Europe. This project previously started in Moldova and has now been extended to several countries, including Latvia.
The quality checks in the challenges for this project are mainly focused on potential issues that would impact the road network and tags that affect automotive navigation applications.
Note that additional information is available in each challenge description. Furthermore, some challenges will occasionally show only a few or no tasks. We will update these challenges as new data becomes available. Additional challenges may also become available later on.
We will begin working on these tasks in a few weeks.
Here is the project for multiple countries including Latvia:
