true, but is that really an issue here? why (in this context, with no disputes of the magnitude of those in cyprus) would someone do that? what if someone does delete a road sourced from linz, and then draws it in again? the source of the information for that road is no longer linz, it's the person who re-drew it, isn't it? > For a more practical example related to mass imports: > The waterbodies from the AND import in the Netherlands are often less > accurate > than the Yahoo aerial imaging that has recently become available here.
