Maybe Japanese mapper can help you. Mapping Tokyo must be similar.

Nice map but I would not spend too much time in fast food restaurant mapping rather highlight your regional food.

Ich mache es gar nicht. Ich denke traffic_sign=city_limit dürfte der korrekte Tag sein.

Try to get in contact with those mappers overwriting your work. In most of the cases it happens unconsciously.

Had you had a chance to read this osm.wiki/User:Oxomoa/Public_transport_schema ?

I've started to put bus stops on the road and will later add bus platform in the relation.

Regarding osmdiff. In order to diff only your area try folowing
1. create a polygon file from your area
2. download from from planet.osm that file that covers your work
3.Extract your area via osmosis like my example below
osmosis --read-xml file="baden-wuerttemberg.osm.bz2" --bounding-polygon file="hohenlohe.poly" --write-xml file="hohenlohe_07.osm"

Open a issue in https://josm.openstreetmap.de/

I regularly run a difference report on my area with osm.wiki/Osmdiff. I guess that could be useful in your case. If you need assistance let me know.

You could use your user page in wiki.openstreetmap.org and post a link in your diary only.

Some Germans have put their thoughts on the wiki. See for more here osm.wiki/User:Oxomoa/Public_transport_schema

Schau dir die Daten doch einmal an in Potlatch. Auffahrt und Abfahrt sollte auf jeden Fall mit oneway=yes getaggt sein plus der korrekten Richtung.
Die meisten Daten in OSM sind noch nicht validiert deswegen auch mit Vorsicht zu geniessen.

I've submitted a plugin to support TangoGPS in JOSM recently. After deployment you can load your files without conversion.

If there's a bug in JOSM maybe I can help with. Drop a short note with the issue number.

Switch to merkaator which gives you the possibility to add a comment. It's better to work with in all aspects compared to Potlatch. I'm using Potlatch for very small changes only.

It doesn't work on Mac as only Silverlight V1.0 is supported at the moment. I get an error message in Safari.

Was bedeutet alle Bushaltestellen einer Linie zu einer Relation zusammengefasst? Ziehe ich dann einen Linie von Punkz tu Punkt?
