Hi Thorsten, the road speed assignment of a road is performed as follows: 1) Use road_speed from the element definition (7 in your example) 2) If mkgmap:road-speed-class is set use this value instead 3) If mkgmap:road-speed is set use this value instead if it is a number only. If it starts with + or - modifiy the value retrieved in 1) and 2). Also limit this value to mkgmap:road-speed-min/max if applicable. So for your example road speed=4 is used for a motorway with maxspeed > 60kmh. Road speed=7 is used for all motorways with no maxspeed or maxspeed <= 60kmh. As you can see road_speed in the element type definition works as default value. It is not possible to check if the road_speed is set in the element type definition. WanMil
Hi,
I have a question about mkgmap:road-speed-class and the road_speed/road_class elemets.
The documentation only writes that "mkgmap:road-speed-class" overrides "road_speed". But if I use "road_speed", what does this mean for "mkgmap:road-speed-class"?
Example:
highway=motorway [0x01 road_class=4 road_speed=7 level 3] maxspeed=* & mkgmap:road-speed-class!=* & maxspeedkmh() > 60 { set mkgmap:road-speed-class = 4 }
Will the second rule overwrite the first one? If yes, how can I check if road_speed was already set or not? If not, will the second rule have ever any affect?
This construct is used in the default mkgmap style, setting road_class/road_speed in the action block, and later according to maxspeed in inc/roadspeed.
Thanks, Thorsten
