Yes, but long term I can see people using openstreetmap data just for navigation, and having their traces would be very useful for traffic modelling purposes to improve the routing algorithms. In this case the only real information OSM has on these people are their traces, so we would need some sort of protection in place if they are worried about this sort of thing. One solution might be to always drop the last and first N minutes, kilometres, turns, etc. from every journey, where N is a random number chosen uniformly from a fairly wide range (between 5 and 10 minutes). This would ensure that most of the travelling information is kept, but no information about start points and destinations are. These end points would be less likely to be useful for road-speed modelling anyway. Also, does everyone here realise that private traces still show up for everyone in JOSM/Potlatch/etc. (without any timestamp or user information)? It just means that the files are not visible in your traces area on the website. Ie. the gps points themselves are still publically accessible through the API, you just can't tell who made them or at what time they were made. - David -- View this message in context: http://www.nabble.com/Hi-all-...-tp24072661p24134109.html Sent from the OpenStreetMap - Australian Talk mailing list archive at Nabble.com. _______________________________________________ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
