As most maps probably don't need this fix, here's a version of the patch that doesn't do the arc length limiting unless you specify the "--limit-arc-length" option. I have made the diagnostic message that is output when an arc length is too long into an error (was a warning) and it spells out what to do to get around the problem.
I tried out the patch on mkgmap r1022, and it made me aware of the problem with http://download.geofabrik.de/osm/europe/finland.osm.bz2 by emitting two identical warnings: SEVERE (RouteArc): Way null contains an arc whose length is too big to be encoded so the road will not be routable (you may use the --limit-arc-length option to work around this problem) [Suggestion: could it print the ref or the id if there is no name?] After adding --limit-arc-length, I got a different error message: SEVERE (StyledConverter): Way null contains a segment that is longer than 16383 (routing will fail for that way) Mark, could you have a look what is going wrong? I'm running the script at http://www.polkupyoraily.net/osm/files/osm2img.sh essentially as follows: splitter.jar --split-file=areas.list finland.osm mkgmap.jar --limit-arc-length -c mkgmap.args --family-name="OSM 28.04.2009" The referenced files are here: http://www.polkupyoraily.net/osm/files/areas.list http://www.polkupyoraily.net/osm/files/mkgmap.args Best regards, Marko
