Both maxspeed=countrycode:zone type and maxspeed=zone type are evil, as we need to have a separate DB for those zonal limits. Please, just use maxspeed=number. -- Cheers, Andrew ___ Tagging mailing list Tagging@openstreetmap.org

I disagree with just using a number, the tags are there to indicate that the mapper had interpreted the speed limit from the type of road. Should the limits change they make finding the limits that require changes easier. The number should be tagged, and I would not expect a data consumer to use

There are several differences in my view: 1. When viewing the map offline, the user wants to see only rural roads when zooming out really far. 2. If you don't have maxspeed for a particular way, a clever app that knows typical speeds for each type of way in each country can make a more educated

Osmand and pretty much any other nav software worth it's salt already interprets maxspeed (though I wish minspeed was also factored in more often). On Jun 17, 2014 4:25 AM, Philip Barnes p...@trigpoint.me.uk wrote: I disagree with just using a number, the tags are there to indicate that the

2014-06-14 Thread Fernando Trebien
Hello everyone, Time and again I get myself thinking why is that we use a single classification system for rural and urban ways. To me, an urban tertiary is usually very different from a rural tertiary, both physically and functionally. For several applications, such as navigation software, a
