Re: [mkgmap-dev] opposite-cycleways option

[Gerd Petermann]

Hi Joris,

the java code creates a copy of the original way and removes various possibly 
existing access tags, it sets
access=no, bicycle=yes,oneway=no,mkgmap:synthesised=yes

I would not add foot=* as the original might have something equivalent to 
foot=no.
In fact there should be no need for any special handling in the style unless 
you want to assign a special typ.

Gerd

Betreff: [mkgmap-dev] opposite-cycleways option

Hi,


I’m trying to improve routing for my bicycle and the oneway allowed for 
bicycles by using the --make-opposite-cycleway option
But I was wondering what the criteria are for creating such extra cycleways.
I have read some earlier posts an ’ll found Gerd’s  comments on 
http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2014q2/020818.html

But the manual does not state what is actually implemented. Is there some more 
documentation somewhere?

As far as I understand now

  *   Only if a highway has oneway=yes AND (some variants of oneway:bicycle = 
no) then
  *   Mkgmap will create an extra highway line with (mkgmap:synthesised = yes)
  *   Within my style file I’ll pick up the mkgmap:synthesised=yes and assign 
an “invisible overlay routeable highway” line and then
 *   Remove the oneway-tag (which applies to cars)
 *   set mkgmap:bicycle/foot=yes
 *   set mkgmap:car/hgv/bus/delivery=no

Is that correct?
Thx for helping me out

Re: [mkgmap-dev] Fix Sea Patch

[Mike Baggaley]

HI Gerd, I don't have a build that includes the PrecompSeaGenerator, but I
would expect the impact to be the same as for in-line sea generation: an
increase in execution time if /check is specified with a reduction if it is
not specified.

I'm not quite clear what happens if you specify --precomp-sea, but don't
specify --generate-sea. The help only says that --precomp-sea can be
combined with --generate-sea but doesn't say what happens if you don't.
(Does it switch on --generate-sea=multipolygon?)

I think the order of the options in the documentation is not ideal either -
I would think --generate-sea should come first, followed by --coastline-file
and that followed by --precomp-sea. Happy to tweak this.

Cheers,
Mike

Hi Mike and Ticker,

do you expect an impact on the PrecompSeaGenerator?
