[mkgmap-dev] Bad tile around East London / Greenwich

Sat Aug 7 10:24:40 BST 2021

Hi Jan,

I think r4805 fixes the problem. I've not analysed why the default style doesn't show the problem. The routing data is very different.
It seems that the OFM style produces a lot more restrictions.

Hi Jan,

I can reproduce the problem with the OFM full style. With the just released r4804 I see this:
SCHWERWIEGEND (global): Bad file format: e:\Jan\10700105.osm.pbf
uk.me.parabola.imgfmt.FormatException: too many restrictions

        at java.lang.Thread.run(Thread.java:748)

I think this problem is caused by an error in mkgmap, it seems to put too many restrictions into one so called RouteCenter.
Have to check the details...

Hi Gerd,

yes, but only on my own style:
SCHWERWIEGEND (global): Bad file format: 10700105.osm.pbf

File uploaded here<https://files.mkgmap.org.uk/download/517/10700105.osm.pbf>. It is splitter-generated from a geofabrik great-britain-latest with max-node=1400000.
Splitter 615 and mkgmap 4802.

For my own and and the default I have the same splitter options:
java -Xmx26000m -jar splitter.jar --output=pbf --output-dir=/great_britain-splitter --max-nodes=1400000 --mapid=10750001 --geonames-file=PRECOMP/cities15000.txt --polygon-file=ARGS/great_britain.poly DATA/great_britain-latest.osm.pbf

And mkgmap then:
java -Xmx26000m -jar mkgmap.jar --output-dir=great_britain-output -c ARGS/great_britain-HGT.args -c great_britain-splitter/template.args ARGS/10000.txt

Hi Jan,

Any error message from mkgmap?
I can try to reproduce if you upload the input osm file to https://files.mkgmap.org.uk/
(or post another download link)
and the options that you use.

Gerd

Hi all,

since some time my map has a bad tile around East London (Greenwich).
I´ve checked earlier revisions of splitter and mkgmap, and decreased splitter´s max-nodes - without success.

Problem seems to be in my style, which is based on OpenFietsMap. With the original OFM-style the error is rendered as well, but not with the mkgmap default style.
But I´ve got no clue where to look for the mistake -  anyone has got a hint for me?
