Hi folk, I'm a mapper from Italy since 2008 but registered to this list only now, mainly to post this. Some mappers, apparently from the US, are using the key "source:maxspeed" to add metadata (the way the data was collected and/or the source of the data) to the database. Unfortunately this tag is already in different use for several years.
The general usage is according to the wiki: distinguish between implicit and explicit speed limits (i.e. the default maxspeed in the context (urban, rural, motorway) and sign posted limits). The idea is to always add maxspeed=number(unit like mph or kmh) to highways and to distinguish where the limit comes from with the additional key source:maxspeed. Now there seems to be some people who add different values like "massgis" or 'FDOT␣"Maximum␣Speed␣Limits"␣GIS␣data,␣updated␣August␣27,␣2011:␣http://www.dot.state.fl.us/planning/statistics/gis/roaddata.shtm' At first glance this looked like an import to me, but apparently it is single very active mappers who use the tag in this way. I'd kindly ask you to use another tag for the information (preferably you could add the source to the changeset comment, but also a similar key like "maxspeed:source" would be fine). Maybe we could also change the existing keys with the 2 above mentioned values to this new key? What is your opinion on this? cheers, Martin _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
