I am trying to build a routable map for all of Massachusetts as a first step towards hopefully improving the style rules slightly (some ramps on Rt. 2 are missing from the cloudmade img and I think it's because trunk_link is missing in the style file, but I haven't figured that out yet).
My command line is pretty much as the one in README.example. After
running the splitter on cloudmade's massachusetts.osm I ran:
java -enableassertions \
-Xmx2048m \
-jar mkgmap.jar \
--tdbfile \
--gmapsupp \
--family-id=632 \
--overview-mapname=40000001 \
--country-abbr="US" \
--country-name="United States" \
--region-abbr="MA" \
--region-name="Massachusetts" \
--description="OSM gdt" \
--ignore-osm-bounds \
--net \
--route \
--add-pois-to-areas \
--remove-short-arcs \
-c template.args > OUT.02.mkgmap 2>&1
As you can see I do have remove-short-arcs. I think I am r1048 but will
update and try again. I got the following errors, which I thought
--remove-short-arcs was supposed to fix. I looked at NEW HOPE WAY, and
it is nearly a loop with very close nodes even though it is really a
simple linear alley for which two nodes would do fine. I looked at
another one (29730871) and that looks bizarre as well:
http://www.openstreetmap.org/?way=29730871
I think the ways appear multiple times due split tiles, which is fine.
The rewulting img/gmapi loads into Garmin mapmanager (mac) but RoadTrip
says it is broken and cannot be used.
So two thoughts:
if ways are still messed up, maybe they should just be omitted?
it would be nice to give a URL to the way instead of just the id. I
suspect a lot of these are messed up and should be fixed in the db
regardless of mkgmap liking them or not liking them.
I have done sort|uniq on the actual output:
