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

Thu Apr 17 23:07:52 BST 2014

Hi,

attached is a reworked inc/access file.

It now uses a 1:1 assignment between OSM tag and mkgmap access tag:
foot=*       { set mkgmap:foot='${foot}' }
bicycle=*    { set mkgmap:bicycle='${bicycle}' }
motorcar=*   { set mkgmap:car='${motorcar}' }
goods=*      { set mkgmap:delivery='${goods}' }
hgv=*        { set mkgmap:truck='${hgv}' }
bus=*        { set mkgmap:bus='${bus}' }
taxi=*       { set mkgmap:taxi='${taxi}' }
emergency=*  { set mkgmap:emergency='${emergency}' }

motorcycle is no longer used. There is no clean solution when motorcycle 
!= motorcar. The default style supports motorcars. Users that want to 
use the cards especially for motorcycling should modify their inc/access 
file appropriately.

delivery is no longer used. It is not an access key. The wiki notes:
The key delivery is mostly used with the value yes to indicate that the 
restaurant offers delivery of your meal.

More access keys are used. They are taken into account obeying the rules 
of vehicle subclasses (set motorcar=no if motor_vehicle=no or vehicle=no 
etc.).

The old rule
highway=path { add foot=yes; add access=no }
did not work for the way [highway=path; access=no]. This way should not 
be used by foot anyway but the rule above errorneously allowed foot. 
This is fixed now.

carpool handling is now disabled. It does not work (as far as I know) so 
the rules are not useful.

Many thanks to Mario Hantschke who worked out some problems of the old 
access file and provided some good ideas for the new rules.

Please check the new rules. If you are unhappy with some assignements 
please post an tagging example of a way and how you think the access 
rules should be assigned.

Have fun!

# Define the access restrictions
# The following tags define the restrictions:
# mkgmap:bicycle
# mkgmap:foot
# mkgmap:car
# mkgmap:truck
# mkgmap:taxi
# mkgmap:bus
# mkgmap:emergency
# mkgmap:delivery
# A class is not allowed to use the way if its tag is set to 'no'

# First set access settings with high priority.
#
# In case a way is tagged with 
#    highway=motorway;access=yes 
# we assume that foot and bikes are not allowed anyhow.
