[mkgmap-dev] don't route through highway=construction

Tue Oct 13 16:12:01 BST 2015

Hi all,

okay, seems I got that tag wrong and so I agree that we should not route through these roads.
The question is how to achieve that behaviour. 
The clause setaccess=no will not work if the way has a tag like vehicle=yes or foot=yes,
as it only sets the mkgmap:* tags. 
Extended types are also taboo for the default style.

Possible solution:
Internally, mkgmap already uses a flag called skipAddToNOD. 
When true, the road is used for address search, but is not added to the 
NOD sub file and therefore will not be routable.
I can add a new tag mkgmap:add-to-NOD=false for this.

I agree that 'highway=construction' should be omitted from routing.
That to me indicates "they are building a road but it is not usable".
If the default style routes over that, it's just a bug and should be
fixed.
