I can try, but > I've had no reply to an email sent to him a couple of days ago nor have I, so it is mainly guesswork. source:maxspeed does have a page on the wiki http://wiki.openstreetmap.org/wiki/Key:source:maxspeed I've just added the Key template to the page, and to my surprise it seems to be fairly widely used (possibly not all by chriscf...) Why he's adding it? I can't be sure. My guess is the aim is to mark ways that have national speed limit signs whereas the maxspeed=60mph or maxspeed=70mph is the 'implied speedlimit'. I was doing something similar locally using maxspeed:type=national or maxspeed:type=national_dual_carriageway and the reason I was doing this is the occasional news story where the government is thinking of reviewing national speed limits - having those ways subject to such an existing limit in a way I can get them through JOSM or XAPI fairly easily to update the maxspeed values seemed sensible when I started. I had previously used maxspeed=national which is mentioned somewhere elsewhere on the wiki, but decided I'd put speeds on the roads and use maxspeed:type as a personal reference in case it was needed later. Again I'm guessing that UK:nsl_single and UK:nsl_dual are the values that chriscf made up for use with the source:maxspeed tag; my unanswered message to him of the other day suggested they should be documented if he wanted other mappers to use the same values, and explain what they were for. Anyway, I'm currently adding maxspeed:type as I was doing and source:maxspeed just to keep the bot away... > I'm most concerned about the 'inferred' references, which, to me, is > no > better than guessing; something that should not be a part of OSM. Yes - it annoys me too. More than that I've got to now track down all the FIXME:nsl tags which don't seem to show in the available FIXME validation layers I have available currently.
