I managed to upload data to OSM servers using JOSM—though I had to patch it for Cyrillic usernames (well, any non-Latin-1 characters). Thanks to Bruce Cowan for pointing me in the right direction earlier when it came to uploading existing OSM files.

Intersections or overlapping?

Thus, I was able to map most of Zemun's Donji Grad (and a few nearby streets of Novi Beograd), but with a few problems I can't seem to be able to solve.

The biggest issue I am running into is joining ways—some of them seem to not look like intersections, yet they share a node. At least when rendered with mapnik—osmarender looks fine.

Osmarender looks better: or at least doesn't show the same defects?

I'd really like to resolve this, because I want these streets to be actually connected. I've tried inserting 'junctions', but that didn't help. Any suggestions?

Alternative and localised naming

Other thing I wonder about is about alternative names, and localised names (for streets and objects). I am making use of old_name, name:en and name:sr tags, but I couldn't find any official policy on naming.

I have so far defaulted to using Serbian Cyrillic for street names, but will soon switch them to Latin script, and put Serbian as name:sr tags. I suspect search on OpenStreetMap will return both, but will need to wait for confirmation for a few days. I am also still hoping to render Cyrillic names, though, so I may need to set up a separate tile generator on my own server. Or not?

I recently got a blu-max/Eurotronic GPS 101 bluetooth device, hooked it up with my Nokia N800 and started playing with OpenStreetMap.

Mapping

Maemo Mapper is pretty cool. However, I have not found a way to diferentiate between nodes made with 'Insert break' in GPX editing tools like JOSM or Merkaartor: they are completely like any other nodes automatically inserted when 'Enable tracking' is on. Any clue about what am I doing wrong is very welcome.

Also, I am not really sure what the value of inserting breaks into tracks is: neither Merkaartor nor JOSM seem to make any distinction, or am I being clueless? Any hints are welcome :)

Editing

I started importing my GPX files into Merkaartor first, because it was easier to import Yahoo satellite imagery as the background, thus making it easier to confirm I am choosing right points to end roads at (because of the problem of not being able to separate 'breaks' from other nodes in Maemo Mapper). However, I can't upload anything (and I am using Qt 4.3.4), so I am suspecting the 0.6 OSM API change might be the one to blame, though I am still totally clueless about what's going on.

So, I decided to switch over to JOSM, however, I didn't want to lose streets I already marked up. However, JOSM doesn't accept same form of IDs used on <node>s—it expects integer IDs, or at least something that looks like it, and Merkaartor produces a string of hex numbers separated by dashes (it's a standard format, but can't remember the name from the top of my head). So, I hacked up a quick script to "normalize" (or simplify) IDs on all <node> tags, and also remove all nodes not otherwise used in any of the <way>s (though, removal is commented out since it was really slow in xml.dom.minidom).

Uploading

So, I was finally able to open OSM files in JOSM, but I still couldn't upload them to the server: whenever I open an OSM file, it's considered as it's completely in sync with OpenStreetMap, yet I want to push all the streets as new data.

Anybody got a solution to that one? I.e. how to make JOSM consider all imported OSM files as "new" data?
