I would support mapping existing warning signs, but mapping subjective opinions in OSM is not only completely pointless and useless but even harmful.
I am maintaining personal database of issues and problems in my city[1]. Most of it is about cycling-related problems. Idea of keeping that data in OSM is for me clearly absurd. Frequently there it is controversial whatever something is a problem/major hazard/minor inconvenience. [1] I am using it to monitor progress (or lack of it) in fixing issues reported to local government. 2015-03-10 12:29 GMT+01:00 malenki <[email protected]>: > On Sat, 7 Mar 2015 15:26:38 +0100, > Stefan Keller wrote: > > > What about crowdsourcing dangerous bicycle locations using key/tag > > hazard?
