I agree with you that things which you can't verfiy without thousands of dollars of equipment doesn't belong in a generalized dataset like OSM. > 3.

Then you're going to have problems with all of OSM, since we use that rule to handle virtually any dispute. > I am curios what river or wash I just drove > over. It is not posted.

It's entirely possible that the names the locals use for that river differ from the government dataset, in which case, OSM would prefer you use the local name as the primary name, and not the official one. Ground observable in this case is "Local knowledge". Of course that requires consensus, but this is why we have so many tags related to names > 6.

This is based on a misunderstanding of your understanding of what the ground observable rule is. A person who lives in an area and can talk about it will actually trump most other sources, including signage, but that requires that we get lots of people involved and working in a diplomatic way. > 7.

Why not help her ensure that her data be in OSM by being a teaching resource? Also, what does sign names have to do with ground surveying? > 8.

This is quite the stawman argument you've build in my name, but it's not my argument. OSM has a long history of encouraging surveyed data. > 11.

I've never encountered a problem with law enforcement officials when mapping, so I can't speak to your experience. > 12.I am passionate about what I do with OSM and the out reach that I do.

Last year (or was it the year before) at SOTM US, there was discussed with Ian Dees leading the discussion about using municipal data in a separate dataset, and yet I don't see you being as viscous against him. Whether it's deliberate or not, please stop misquoting me to further your arguments. - Serge _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
