[OSM-talk] Tunnel layer

[Ben Laenen]

Hi,

I wonder if it would give better rendering results is we keep tunnels at 
layer 0 instead of layer -1, as stated on 
http://wiki.openstreetmap.org/index.php/Mapping/Features/Tunnel .

At layer -1 the dashed lines disappear under rivers, and even the grey 
areas next to residential roads. Both issues are visible on the map at 
http://wiki.openstreetmap.org/index.php/Antwerpen (West and South 
motorways). The dashed lines should at least be drawn on top of these. 
At layer 0 they would do that, so therefore my question.

Or should it perhaps be fixed in the renderers? Not sure though if 
that's the case since that means displaying layer -1 on top of layer 
0...

In a slightly related note, there's a rendering issue with the South 
tunnel on that Antwerp map in Osmarenderer: it shows a big black area 
next to the tunnel. It's only visible at zoom level 12 and 16.

Greetings
Ben
