Hi Not an answer to your question, but maybe relevant: The default style has, in "options": levels = 0:24, 1:22, 2:20, 3:18 My reading of the "Style Conversion Manual" says that elements with a resolution between the levels are included in the higher res/lower level map; ie. elements with [resolution xx-23] go into the level 0 map. So, according to this, you will be getting 2 lines on top of each other at the most detailed level. If this isn't the case, the manual should be clarified.

Hi All
I noticed default style uses extended types for roundabouts with a matching routable line. However extended lines are plotted starting at a lower resolution, ie
Resolution 24 junction=roundabout & (highway=trunk | highway=trunk_link) [0x0c road_class=4 road_speed=2 resolution 24 continue] Resoiution 18 junction=roundabout & (highway=trunk | highway=trunk_link) [0x10801 resolution 18]
In this case it does not seem to matter if 0x0c starts at resolution 24 rather than 18, or does it?
Can we presume that all routable lines only require resolution 24 , ie
a) highway=motorway [0x100 resolution 16-20 continue] # thinnest line b) highway=motorway [0x101 resolution 21-23 continue] # thinner line c) highway=motorway [0x01 road_class=4 road_speed=7 resolution 24] # default line
Will this affect routing across tiles ?
At the moment I'm adding a transparent routable line to a & b ie
a) highway=motorway [0x100 resolution 16-20 continue] # thinnest line highway=motorway [0x17 road_class=4 road_speed=7 resolution 16-20 continue] b) highway=motorway [0x101 resolution 21-23 continue] # thinner line highway=motorway [0x17 road_class=4 road_speed=7 resolution 21-23 continue]
Any ideas?
Thanks
Nick
