I guess the editing was done with Potlatch? Not by robot?
Used have to use key "c" to close the changeset and start a new one.
Or stop working for at least one hour.

I not an expert of Potlach, but I think you have to press "c" to close a changeset and give a comment. Otherwise it will be closed by a timeout after maybe 1 hour. See osm.wiki/Potlatch/Keyboard_shortcuts

Yes I found many too :-)
Many of them I made myself :-(

Testing routing is good, but it's easier to find these errors using
http://keepright.ipax.at/report_map.php
looking at almost-junctions, floating islands, intersections without junctions

For your example you can find a bunch of errors:
http://keepright.ipax.at/report_map.php?zoom=14&lat=47.96886&lon=10.81076&layers=B0T&ch30=1&ch40=1&ch50=1&ch60=1&ch70=1&ch90=1&ch100=1&ch110=1&ch120=1&ch130=1&ch150=1&ch160=1&ch170=1&ch180=1&ch190=1&ch200=1&ch210=1&ch220=1

Looks good now. Thanks. Great job.

Harry I think you are right. Thanks for the links.
I was able add ways to relations, but maybe it's better to wait a little bit
or use JOSM.

In JOSM they are fine. So it seems to be a problem of Potlatch.

OSMtracker is a free program for a pocket pc/smartphone
see osm.wiki/OSMtracker
The voice recordings have a preset timelimit, e.g. 5 seconds.

I use my pocket PC and OSMtracker to voice record. It shows nice in JOSM.

The PDA off button is a "lights-and-touchscreen-off-combination" only after 2 minutes it really switches off.
OSMtracker osm.wiki/Osmtracker
uses something like ResetIdleCounter to prevent the pda from switching off.
I use it switched off to log data.

What program do you use to view the pdf?
Now I used Acrobat Reader 9.1 and it also fails.
Before I was using Reader 8.x

What format, what scale, what area?
I can export the center of Rome as pdf.

Not for me, but can you send an example where you have holes?

Can you see your edits in Potlatch/Edit ?
If not, they are not in the database.

I use an iBlue 747 like amillar. A newer version is sold here:
http://www.outdoortrends.de/ausruestung/gps/transystem-iblue-747a-gps-recorder.html

Price in Germany is 65 EUR + 2,30 EUR

you can reach him as keepright having a mailbox at gmx.at
See impressum in http://keepright.ipax.at/ at the end.

Ja genau. Dann weisst du noch, dass es ein Wanderweg war und musst es nicht nochmal ablaufen, wenn dein GPS-Empfänger in die Feldspalte gefallen ist :-)

Die Idee beim "nur Track hochladen" ist wohl, dass ein Mensch mit GPS-Logger nur Daten sammelt. Dann kann ein anderer Mensch, der keinen GPS-Logger hat und die Wege kennt bzw. erkundet, damit mappen.
Da du ja einen GPS-Empfänger hast, bringen fremde Traces nicht viel.
Manchmal ist es auch gut dreimal den gleichen Weg getraced zu haben, vielleicht nur einmal von dir, so wird die Genauigkeit vielleicht besser.

Die einzige Idee, die mir da einfällt ist:
osm.org/traces/tag/ORTSNAME

Wenn dich die GPS-Tracks stören, die andere hochgeladen haben
und du hast die in Potlatch mit Taste "g" eingeblendet.
Dann probier doch mal Shift-G, dann solltest du nur deine eigenen Tracks sehen.
Oder du gehst zu osm.org/traces/mine oder @schreck/traces suchst dir einen Track aus und klickst auf edit.
