[mkgmap-dev] [PATCH v1] Rework of inc/access

Fri Apr 18 07:43:28 BST 2014

Hi WanMil,

besides the error reported by Stéphane here are my 50 cents after a first
compare
with the unpatched default style:

I am not sure, but I think tags like 
vehicle=private, motor_vehicle=private etc.
should not set 
mkgmap:emergency=no

My interpretation regarding routing is that
it is equivalent with xxx=destination, 
so it should set the no-throughroute bit.

Reason:
If one wants to visit someone living at a private way, we can assume that
he is allowed to go there. On the other hand, a route restriction  
like a no_left_turn might be ignored if the road in the img file 
doesn't allow any vehicle.

The problem : We have only one no-troughroute bit for each road segment, so
a way with highway=*, access=private, bicycle=yes,  foot=yes
has to be added as two roads, one with acces for all vehicles except bike
and no-throughroute=true,
the other with full access for bikes and pedestrian.
This can't be done in the finalize rules, right?
