I think you can't define this on a global level, it depends heavily on the local activity whether it makes sense to enter a mid-term interruption into OSM or ignore it. > When you look into cat manufacturer supplied satnav systems people drive > around with 4-5 year old maps - which are still perfectly okay. > > With OSM-data I wouldn't expect someone to use 4 or 5 year old data on the other hand ;-) > If we start tagged ultra-short-term problems the maps cant be put into > offline systems like in-dash satnavs. > offline systems without updating possibility will always have the problems you get with a single snapshot (e.g. errors introduced by novice mappers or for other reasons and corrected shortly after, e.g. recently we had such a case in the Italian motorway system which caused a deviation for everyone using this motorway (one of two for North-South-connections, so roughly half the long-range traffic). I think we should discourage people from mapping the current state just because it might change in a few months and people using old data and not updating it would have problems, instead I believe that real time data will get even more important than it is already now. cheers, Martin
