Hello, Yes indeed some European countries are going further into smaller details. And it's legit. However, in the Canadian context, it seems that adjust & fix massive CanVec data imports has higher priority than touching up every single landuse parcel....
It's not only about woodlands & water, but also some conversion errors like Canvec "schools" converted into "jails" in OSM. So every single little village in QC has his own little jail ! Funny? ;) (Some of them have been fixed...) And double-space in street names is also a pain when using Nominatim .... "Zero un-taged pixel world map" is high hope :-) Greatings !
