Wouldn't it be better to amend the tagging in OSM to accurately describe what is actually on the ground? - road the majority of the time, runway, the minority.
I maybe wrong, but it appears your using mkgmap to paper over the cracks in OSM.
What tagging would you propose then? I think that highway=* and aeroway=* on the same way describes exactly this situation. Not all straight road sections can be used as runways. I would not remove the aeroway=* even though it might be used as such once in a year or so (and closed from general traffic). The aeroway=* could be useful for an OpenAviationMap that would display airfields from a much greater distance than highways. Marko

Someone notified me that this highway that serves as a temporary runway during military exercises is not being considered for routing:
http://www.openstreetmap.org/browse/way/45772320
aeroway = runway highway = primary name = Turuntie ref = 41
The obvious reason is that in styles/default/lines, aeroway=runway comes before any highway=* tags. I confirmed the non-routeability on my Edge 705, and my fix sort of worked:
Index: resources/styles/default/lines =================================================================== --- resources/styles/default/lines (revision 1652) +++ resources/styles/default/lines (working copy) @@ -8,8 +8,8 @@ # and http://wiki.openstreetmap.org/wiki/Mkgmap/help/Custom_styles # for more information.
-aeroway=runway [0x27 resolution 20] -aeroway=taxiway [0x27 resolution 24] +aeroway=runway [0x27 resolution 20 continue] +aeroway=taxiway [0x27 resolution 24 continue]
# Contours take their name from the elevation setting. contour=elevation & contour_ext=elevation_minor
I would have preferred to see the runway on top of the highway, but the Edge 705 rendered only the highway. In other words, the Garmin line for the aeroway=runway object is just wasting memory. QLandkarteGT showed both lines on top of each other.
I think that we should just move the aeroway=* rules below highway=* so that any highways that serve as temporary airfields will be translated as highways. Any objections to that? Are there any aeroway=* that are also tagged as highway=service, for example? Should they require some special treatment?
