Hi Andrzej,

sorry, I somehow missid this post before. I agree in all points.
The "create_area" function  seems a bit too special as it only makes sense for 
maps without a TYP file, right?

Betreff: Re: [mkgmap-dev] aeroway in default style

Hi Gerd,

I can't see any easy way to make runway visible over a road, without
using a TYP.

I treat default style as some kind of reference. An attempt to solve
this problem would result in cluttering of the style or use of
non-standard objects. Both approach would destroy educational values of
style and probably results would be rather mediocre. So I prefer to
ignore runway.

W can create additional POI for this kind of runway, but I think mappers
add a POI anyway, so this could be superfluous.

Just a thought: if we get a function like line-to-area, then w could
draw a runway below road as an area. I imagine rule like this:

aeroway=runway & highway=* & is_closed()!=true { create_area(20m); }

This should result in a new polygon created as a strip with 20m width,
which then would be processed according to rules in polygon file.

Andrzej
