[mkgmap-dev] [patch v3] reverse oneways

From Gerd Petermann gpetermann_muenchen at hotmail.com on Wed Apr 30 11:46:59 BST 2014

Hi Felix,

no, since 1272 routable ways with tag oneway=-1 or oneway=reverse 
were reversed after style processing.
Note that these old versions also may have used
one instance of the way, so maybe with your style
the reversing was done multiple times.

Anyway, as you said the behaviour with the patch
is much more predictable.
I'll check if I have to modify the code for
the restriction relations as well.

          Is it only 

          > oneway=-1 that's reversed by mkgmap? Or are there other
          tags?

          

          yes, oneway=-1 and oneway=reverse. I don't know why the 2nd
          alternative

          is needed, tagInfo doesn't show that oneway=reverse is used.

          I can't confirm that. Routable ways with oneway=-1 or
          oneway=reverse

          were reversed since r1272.

        
      
    
    Yes - but before processing and the tags were kept intact. That's
    why I need a left pointing arrows for oneway=-1...

    However if I now with the patch add oneway=-1 the way is actually
    turned around... - before there was no turning around once the
    style-file was read in...

          (oneway=reverse,

          time.). Are there 

          > other tags like bicycle=oneway that will change
          something?

          

          mkgmap treats oneway=1 and oneway=true like oneway=yes,

          oneway=-1 is treated like oneway=reverse. No other

          values are recognized, so 

          oneway=forward and oneway=backward are ignored

          and have to be handled in the style.

          

          bicycle=oneway is not handled by mkgmap, but

          bicycle:oneway and oneway:bicycle are treated by the
          make-opposite-cycleways 

          option.

          

          There are still some other tags without prefix mkgmap: that

          are interpreted, e.g. barrier=*, highway=*

          Maybe this should be changed in the future.

        
      
    
    Is it possible that there has been some changes regarding barrier in
    the last 6 months too? I think some of the handling changed as
    well..

    

    

    1. 

    I hope that this now gets me the right result:

    ( copy=99 | copy=98 ) & highway=* & mtb:scale:uphill>2
    & mtb:scale!=*   {set mkgmap:unpaved=1}

    ( copy=99 | copy=98 )& highway=* & mtb:scale:uphill=5 &
    mtb:scale=* & mtb:scale!=5    {add mkgmap:taxi=no; set
    dontadd=oneway}    [0x10f0a resolution 21 continue with_actions]

    ( copy=99 | copy=98 )& highway=* & mtb:scale:uphill=4 &
    mtb:scale=* & mtb:scale!=5    {add mkgmap:taxi=no; set
    dontadd=oneway}    [0x10405 resolution 21 continue with_actions]

    ( copy=99 | copy=98 )& highway=* & mtb:scale:uphill=3 &
    mtb:scale=* & mtb:scale!=5    {add mkgmap:taxi=no; set
    dontadd=oneway}    [0x10409 resolution 21 continue with_actions]

    ( copy=199 | copy=198 ) & highway=* & mtb:scale:uphill=1
    & length()>150 {add mkgmap:taxi=no; set dontadd=oneway}   
    [0x10016 resolution 21 continue with_actions]

    ( copy=99 | copy=98 )& highway=* & mtb:scale:uphill=2 &
    mtb:scale=* & mtb:scale!=5     & length()>30 {add
    mkgmap:taxi=no; set dontadd=oneway}    [0x10016 resolution 21
    continue with_actions]

    ( copy=99 | copy=98 )& highway=* & mtb:scale:uphill=1 &
    mtb:scale=* & mtb:scale!=5     & length()>60 {add
    mkgmap:taxi=no; set dontadd=oneway}    [0x10016 resolution 21
    continue with_actions]

    ( copy=99 | copy=98 )& highway=* & mtb:scale:uphill=5 &
    mtb:scale!=* & mtb:scale!=5    {add mkgmap:taxi=no; set
    dontadd=oneway}    [0x10f0a resolution 22 continue with_actions]

    ( copy=99 | copy=98 )& highway=* & mtb:scale:uphill=4 &
    mtb:scale!=* & mtb:scale!=5    {add mkgmap:taxi=no; set
    dontadd=oneway}    [0x10405 resolution 22 continue with_actions]

    ( copy=99 | copy=98 )& highway=* & mtb:scale:uphill=3 &
    mtb:scale!=* & mtb:scale!=5    {add mkgmap:taxi=no; set
    dontadd=oneway}    [0x10409 resolution 22 continue with_actions]

    ( copy=99 | copy=98 )& highway=* & mtb:scale:uphill=2 &
    mtb:scale!=* & mtb:scale!=5     & length()>30 {add
    mkgmap:taxi=no; set dontadd=oneway}    [0x10016 resolution 23
    continue with_actions]

    --- copy=98 reversed the way actually - so I hope the arrows all
    point in the same direction now.

    However I'm still a bit perplexed what happens to oenway=-1 after it
    is passed in style. Is the following handling what mkgmap does,
    consider highway=path & incline=up:

    

    highway=path & incline=up {set oneway=-1} # Mkgmap now reverses
    the way, and 

    sets oneway tag to a) yes b) leaves oneway tag at -1????

    

    I hope it does a). Everything else would be really strange. I hope I
    manage to adapt my styles to a). Because as with the copy tag, I
    often set additional tags myself - and of course mkgmap cannot
    change them...

    So I hope you see the logic here is really complicated. I'm actually
    still a bit lost on the outcome of what really happens....
    (especially because we have 1. {}  2. continue 3. continue
    with_actions

    

    So

    

    2. 

    dontadd=oneway & highway=* & copy=99                       
                {set oneway=-1; set mkgmap:toll=yes; add mkgmap:taxi=no;
    set mkgmap:unpaved=1; set mkgmap:set_unconnected_type=none}       
    [0x13 road_class=0 road_speed=0 resolution 24 continue]

    dontadd=oneway & highway=* & copy=98                       
                {set oneway=yes; set mkgmap:toll=yes; add
    mkgmap:taxi=no; set mkgmap:unpaved=1; set
    mkgmap:set_unconnected_type=none}        [0x13 road_class=0
    road_speed=0 resolution 24 continue]

    Here I need to reverse the ways - I DO hope that because of continue
    and not continue with_actions - mkgmap is reversing the ways but
    further down the actual before direction is kept and also oneway=-1
    is kept intact too, as continue should not have any implications on
    lines further down the style... (0x13 is invisble in my map, so here
    the focus is only on routing). This is actually for copy=99 the
    first reversal, while it's a reverse of the reverse for copy=98...

    

    3. 

    dontadd=oneway & highway=* & copy=99                       
                {set oneway=-1; set mkgmap:toll=yes; add mkgmap:taxi=no;
    set mkgmap:unpaved=1; set mkgmap:set_unconnected_type=none}       
    [0x13 road_class=0 road_speed=0 resolution 24 continue with_actions]
    

    dontadd=oneway & highway=* & copy=98                       
                {set oneway=yes; set mkgmap:toll=yes; add
    mkgmap:taxi=no; set mkgmap:unpaved=1; set
    mkgmap:set_unconnected_type=none}        [0x13 road_class=0
    road_speed=0 resolution 24 continue with_actions]

    This is actually not from my style. I do hope mkgmap here reverses
    the way, and further down the style only oneway=yes is present as
    tag, and the reversed direction is kept. 

    

    

    

    I have about 500 more lines in my code that are direction dependent.
    So I will experiment now and see if all works as expected... The old
    behaviour was more straight forward - the newer is ligher on the
    style and especially saves me lot of lines in my .typfile. That's
    why I like it and prefer it over the old way even though I don't
    understand it yet completly. From a logical point this big change
    (not the patch that just corrects a complete havoc mkgmap) is still
    a bit a mistery to me...
