Hi, I'm using mkgmap r4287 and trying to process continent files from geofabrik, e.g. http://download.geofabrik.de/asia-latest.osm.pbf.
For about the last six months (today included) I have "drive-on-left-and-drive-on-right" errors for either Africa or Asia:
I call splitter like this:
java -Xmx380000M -jar splitter.jar --max-threads=40 - -mapid=38610001 --search-limit=1000000 /u/ahux/tmp-dir/as/asia -latest.osm.pbf
Wouldn't default value (auto) for max-threads be better Maybe you need --max-nodes={some value lower than 1600000 to fix the road problem later}
The splitter output looks okay, though I note it ends:
Number of MapFailedExceptions: 1
you should check out this error
Number of ExitExceptions: 0
and then I call mkgmap like this:
java -Xmx380000M -jar mkgmap.jar --code-page=1252 --latin1 - -route --remove-short-arcs --road-name-pois --add-pois-to-areas - -index --location-autofill=bounds --tdbfile --max-jobs=40 - -mapname=38610001 --country-abbr=AS --country-name="Asia" --family -id=598 --family-name="OSM_AS" --overview-mapname=as --series -name="OSM Asia (2019 07)" --description="OSM_AS" --generate -sea=multipolygon --bounds=/u/ahux/tmp-dir/as/bounds-latest.zip - -precomp-sea=/u/ahux/tmp-dir/as/sea-latest.zip --style -file=/u/ahux/tmp-dir/as/mkgmap/distrib/mkgmap -r4287/examples/styles/default /u/ahux/tmp-dir/as/3861*.osm.pbf
--road-name-pois - probably not needed anymore. --location-autofill=is_in,nearest better (bounds doesn't do anything). --max-jobs is better without a value. --country_name/abbr best removed as you are covering multiple countries. --mapname should be set per tile - see later. --description ditto. --generate-sea remove; you are using --precomp-sea instead of .../3861*.osm.pbf, use the template file generated by the splitter with -c ..../template.args
and get a *lot* of these:
SEVERE (StyledConverter): /u/ahux/tmp-dir/as/38610086.osm.pbf: Attention: Tile contains both drive-on-left (71473) and drive-on -right roads (51)
I'd expect this from asia & africa; there are a mix of driving sides
and a few other assorted messages like:
SEVERE (MapFailedException): /u/ahux/tmp -dir/as/38610555.osm.pbf: (thrown in RoadDef.writeRgnOffsets()) Overflow of the NET1. The tile (/u/ahux/tmp-dir/as/38610555.osm.pbf) must be split so that there are fewer roads in it
you need to experiment with splitter max-nodes to fix this
SEVERE (RestrictionRelation): /u/ahux/tmp -dir/as/38610173.osm.pbf: Turn restriction (no_straight_on) http://www.openstreetmap.org/relation/9335098 (at http://www.openstreetmap.org/?mlat=-6.405884&mlon=106.829270&zoom=17) via node is not a routing node
Mostly can be ignored. Sometimes these are wrong in OSM, but often they express a more complicated situation than can be expressed in the garmin routing format.
How should I respond to these messages? I mean: can I use mkgmap's output anyway? Or should I try to get upstream data fixed in OSM? (if yes: how can I turn these error messages into a location?) Or should I modify my calls to mkgmap or splitter?
Oh, also another small question: is there any convention/rule/list for '--mapname=NNNNNNNN' or '--family-id=NNN' numbers, or should just make them up? (which what I'm currently doing).
Generally make up the first 4 digits, then append 0001 as splitter - -mapid and it will generate the --mapname in the template file. I use the same 4 digits as the --family-id
Can anybody offer any advice? Many thanks!
Alexis
Hope this helps Ticker
