I have repeated the test with today's portugal osm and pbf files from geofabrik and these are the results: -Calculated routes are the same with or without --preserve-element-order for each osm pair and pbf pair. -2 of 3 tested routes are worse with the pbf generated map. -pbf generated map is slightly smaller than osm one (11.3 vs 11.4 MB), so it seems that some information may be missing in the pbf map.
What version of mkgmap was this with?
r1719
I have made a change today that ensures that the output no longer depends on --preserve-element-order, for identical input files.
Here is what I get with the following files and with mkgmap-r1719:
I downloaded the two files: portugal.osm.pbf (dated 20-Oct-2010 07:17) portugal.osm.bz2 (dated 20-Oct-2010 11:21)
from geofabrik and after converting the pbf to the .osm I verified that they were the same. The only difference was the generator and origin attributes due to differing version of osmosis.
I then converted each file with mkgmap --route --remove-short-arcs The resulting maps were the same apart from the timestamps.
Could you post the exact command line you were using? I assume that any difference must be down to one of the other options.
Commands are the same if both cases, with the only difference in the content of the files passed by -c (see below portugal.args and portugal_pbf.args) java -Xmx600m -enableassertions -Dlog.config=logging.properties -jar mkgmap.jar \ --generate-sea=polygons,extend-sea-sectors \ --route \ --tdbfile \ --latin1 \ --code-page=1252 \ --gmapsupp \ --series-name="OSM-Portugal" \ --index \ --road-name-pois \ --ignore-maxspeeds \ --remove-short-arcs \ --add-pois-to-areas \ --adjust-turn-headings \ --report-similar-arcs \ --link-pois-to-ways \ --location-autofill=1 \ --drive-on-right \ --check-roundabouts \ --check-roundabout-flares \ --style=mio \ typ/PORTU-22.TYP \ -c portugal.args args files are also the same, with the only difference in the input file: product-id=1 family-id=22 family-name=OSM Portugal country-name=PORTUGAL country-abbr=POR area-name=Portugal mapname: 63240006 description: PT-Lisboa input-file: portugal.osm / input-file: portugal.osm.pbf
