Well, nearly all my contributions have no source tag. My assumption when I joined was that all mapping was assumed to be from some form of personal survey, usually gps, unless indicated otherwise. When I noticed the source tag, I assumed that its primary use was to acknowledge some 3rd party, but legal, source. It seemed silly and redundant to add an extra tag for gps survey which I took to be the default. Surely I am not the only one who interpreted things this way? So far as I recall, when I looked at other people's contributions in my area, I seldom saw a source tag. That reinforced my assumption. ael _______________________________________________ newbies mailing list [email protected] http://lists.openstreetmap.org/listinfo/newbies
