Talk:Layer

Use on areas (and osmarender rules)

I've just been tagging parks, and woodlands within parks, inside an amenity=university . The area tagging causes some problems:

To make a woodland appear above the purple area of the university campus, we have to use the layer attribute, e.g. natural=wood; layer=1. But that makes some paths and roads disappear 'under' the woodland.

• layer=1 required to put woodlands above the park, but makes the path disappear
• layer=1 required to put woodlands above the university

I don't want to put a higher layer on those paths just to make them render, since technically they're ground-level paths.

Is there a problem with putting motorways under non-motorways?

It works fine when a motorway is depressed and something else crosses over. But when a bridge crosses over an elevated motorway, it doesn't seem to want to put the bridge on top. See the Manhattan Bridge - strangely the pedestrian path works but the roadways and cycleway don't. --NE2 20:46, 13 December 2009 (UTC)

It's question to Mapnik, because on Osmarender work good. --Canabis 09:37, 15 December 2010 (UTC)
