Well, yes, and I do quite often expand the source tag to try to convey more. But in your example "high" accuracy is a problem. If I was using differential gps with cm accuracy, I would call that "high" accuracy. In the present case, the accuracy is not really known, but probably approaching a meter. But I guess that sort of thing could be included in a source tag, although free form text might be better in a note tag. But my impression is that many armchair mappers just don't look. ael _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
