Re: [mkgmap-dev] highway count not fixed yet... - merge-roads-branch

3 Oct 2013

      I'm having problems compiling mkgmap with this patch... (trunk1 is my 
folder for the merge-roads branch).
dunno really what's going on here...
I only have jdk 7 installed (update 40) and uninstalled java jdk7 and 
jre7...

Hi Gerd,
in my opinion recalculating the highway counter after removing the 
short arcs should fix all problems, shouldn't it?
I've added three changes to the patch:
1. When calculating the highway count ways with duplicate id are not 
considered. This avoid that all points of a duplicated way are 
preserved by all filters.
I think this should be modified a bit. For the first and last point of 
those ways the highway count should be increased and also all points 
where another way is connected. I have no use case where this matters 
but I think it is the "correct" counting?
2. I have added the problematic point in the error message of the 
MapBuilder in case a node is not a CoordNode. Just having the way id 
might not be enough information and the way also might have been merged.
3. I have moved the recalculation of the highway counters after the 
merge procedure. This should not change anything but it avoids a 
problem with merging...

Hi Felix, WanMil,
attached is a patch that might solve the problem.  I was still not able
to reproduce it, so
it's just a guess: In a special case, we create a new Coord instance to
replace a CoordPOI
instance. This new instance has highway count = 0. A very special case
might be that this point is later used to split the way, in that case it
would
have highwaycount=1 for a first or last point of a road.
The patch increments the count when the coord is created.

no, I don't use any roundabout command like options, but adjust turn
headings?? -- see below for all commandline options. From style I don't
call much except loads of continues and continue with action, as well as
some link to pois stuff like reduce road_class/road_speed.
On the old version the only very occasional problem note I get is the
following - in this case for Bayern (Germany Bundesland) Geofabrik 
extract:

and for most countries:
set indx=--index (not using index for Asia continent as asia continent
with index was crashing in Basecamp/Mapsource very often, only few
compiles actually worked)
set max-jobs=--max-jobs=8 (for some countries 7 as I ran out of memory
on them and server started to swap=slower)

Hi WanMil,
at least we should know if options like frig-roundabout are used.
    Afaik the default style will never touch these
    routines. I guess Felix uses almost all.
