The OSM map in Poland has a lot of data from the sister project www.ump.waw.pl
UMP works with CC-BY-SA license and allows OSM user data import ( because the same licence)
Due to licence change (from CC-BY-SA to ODBL) are this data (also when modified) now deleted.
The distroying machine form OSMF works now. The beginning is the south west of the country.
Many cities are fully deleted.
We need temporarily help with remapping from Bing images.
I believe, there is no othec coutry with such amount of deleted data.
If somebady want to do “humanitarian mapping” please look in the wiki table:
