Mapping from Yahoo without ground knowledge is legitimate. Tagging the source as Yahoo implies that it maybe out of date & another, more accurate survey, should be carried out in the future but that shouldn't hinder adding the data. I don't think the tag as used implies that,All the traceable images imply a relative accuracy based when they were issued.Yes, but how many people - upon completing a ground survey and editing somebody else's objects that have already been added with a "source" tag - promptly remove or amend that tag?
I've done it about half a dozen times today updating NPE to Streetview.
How many people trace features following a survey and add the tag to bits they traced from imagery, having previously confirmed that it existed on the ground? It's a handy little tag, but not exactly reliable.
If it's completely from a survey then tag it 'survey' if it's a bit of both then - 'Yahoo;survey'
Anyhow, you made a few presumptions in your posts. Just because you think people don't do things a certain way doesn't mean that others shouldn't either. If you think it's the correct way to do something, then do it! - Lead by example.
