Yes there are such vandals, and they will ignore everything. But since i have used source tags, my work gets vandalised much less. Furthermore, the changeset comments are pretty useless in this area. When I am mapping in an unfamiliar area, I try to assess whether my information is better than the current mapping. I use a rather accurate gps unit, photography and gps tagged video as my primary data, usually also checking on imagery, and the public gps traces. Obviously I check on the source tags, and sometimes check the changeset comments if in doubt. However, mapping already takes far too much time, and there is no way that I am going to consult every changeset for each object I modify. But I can't help seeing any source tag. They are needed! > IMHO source tags are only useful for armchair mappers that want to > check other peoples work without going out and checking the reality. As above, I need then to avoid trampling on other people's work. ael _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
