[mkgmap-dev] WG: Mapping smoothness and surface to maxspeed

Mon Oct 24 18:29:18 BST 2016

First I must correct myself, the value mkgmap:road-speed-max is not stored in
the img, it is used to limit 
the road_speed value which is stored in the img. So, the rule sets
road_speed to the minimal value, in inc/roadspeed a maxspeed value <= 10
also makes sure that this min value is used. 
It is up to the Garmin device how this value is interpreted, the PC programs
allow to define what e.g. road_speed=1 means. In PC programs like Basecamp
there is an option to configure the meaning,
I am not sure if the value is interpreted as avg. speed or as maximum speed.
