I’m totally rebuilding the city collection within Poland. Someone pointed out that imported the wrong admin level, so I’m fixing that by taking these steps for each region in Poland:
- Removing all of the existing cities/streets/nodes
- Updating which admin level to import
- Importing all of the cities/streets/nodes across Poland for the correct admin level
During this process, you’ll see cities disappear from your list & then new cities re-appear. It’s a fully automated process that’s already started, so I don’t expect it to take too long. Probably just most of today.
After this completes, if there are still missing cities, you can help out
