[mkgmap-dev] Rendering Tunnels

Wed Oct 22 07:37:47 BST 2014

Hi Enrico,

I think this change should NOT have an influence on routing, so it would be an 
error in mkgmap if it does.
Please double check this result.

Dzięki Andrzej! By removing  "road_class=2 road_speed=3" from the 2nd line, routing works and tunnels are visible - here is how it looks line:

highway=secondary & ( network=e-road | int_ref=* ) [0x04 resolution 18-19 continue]
highway=secondary  [0x04 resolution 20-21 continue]
highway=secondary & tunnel=yes [0x11 road_class=2 road_speed=3 resolution 22]
highway=secondary  [0x04 road_class=2 road_speed=3 resolution 22]
All looks fine now, and routable!

This is correct. I have assumed that you'd like to get 2 lines for tunnels: standard road and additional marking for tunnel.

As I understand, routing parameters are only valid for layer 24 (or the last layer in a map). I would remove road_class and road_speed from line:

highway=secondary  [0x04 road_class=2 road_speed=3 resolution 20-21 continue]

Maybe this is the reason for routing errors?
