[mkgmap-dev] Error message WrongAngleFixer

Mon Apr 23 20:30:55 BST 2018

Hi all,

I've contacted the author Adrian Dempwolff, he agreed that a filter to reduce redundant points is a good idea but has no time right now
to implement it.

Hi Arndt,

I also did not find any option for phyghtmap which would control this. I also looked at the source and found no algorithm to simplify the generated ways.
I think I'll contact the author.

Hi Gerd,

thank you. Know mkgmap run without the error-message. :)

The redundant points in my contour lines...I dont know what to do. :(

Hi Arndt,

this was fixed with r4172:

Hi Arndt,

I am working on a fix for this problem. I think I'll use the Douglas-Peucker filter with a very small error value to remove those duplicate points.

Something you might want to change:
I've noticed that your files contain a lot of elevation lines which also have many redundant points. I don't know which phyghtmap parameter would
change that but there is really no nead to write all those points, pass them through splitter and finally remove them again in mkgmap.

Hi Arndt,

it seems that these ways are causing trouble:
https://www.openstreetmap.org/way/203282008
https://www.openstreetmap.org/way/450539752

In both cases the mapper has added a huge amount of nodes to map a circular part of the way and the 20 passes to reduce wrong angles are not enough.
Please ignore the error message for now, I'll need more time to find out why this is causing stress. It is probably related to the latest changes in the angles branch.

Hi Arndt,

there is nothing that you can do. I'll try to reproduce why 20 passes are not enough.

Hi @all,

mkgmap r4165 tell me this:

SCHWERWIEGEND (WrongAngleFixer): .\Baustelle\Speiche_Fabrik_Splitter\88014475.osm.pbf: Removing wrong angles - didn't finish in 20 passes, giving up!
SCHWERWIEGEND (WrongAngleFixer): .\Baustelle\Speiche_Fabrik_Splitter\88013939.osm.pbf: Removing wrong angles - didn't finish in 20 passes, giving up!

What does that mean and what can i do to correct this error.
