Very helpful. And to be clear is says their should be a space between the number and the unit, ie '50 mph' not '50mph'. > > > The UK uses miles. so the first option doesn't apply > In the UK, the correct value would be '30 mph" , NOT a value in kph. > > If applications don't cope with mph, then they need updating as > they're > not following the specification. > > Adding another log to the fire... > Is there a case for specifying knots in the same way as mph for > waterway > tags? > for speed limits in harbours, canals, rivers, ,,, Makes sense. Another log... What about trains? Network Rail use mph, so I would suggest we do the same. So..... are we reaching a point where we should do some clean-up work on the current tagging? Would that be appropriate? Should we add a space where required and convert the various km interpretations to either fit the proper km conversion from the table, or convert to mph. Is this something that Potlatch can do reasonably efficiently?
