Every EU country must have Land Parcel Identification System (LPIS).  Almost all
countries base it on orthophotos, which must be pretty accurate (RMSE <2.5 m)
and no more than five years old. An example from Czech republic is good reading
as an introduction http://www.lpis.cz/index_en.html. In short, very fine images
exist, as well as very accurate data about actively used fieds. In most coutries
neither images nor field parcel data are free but they can be used only for
administrating and controlling farmer subsidies.
