Chaos99's Diary

Recent diary entries

I was just putting this on the discussion page for the restriction relation.
Thought mentioning it in the blog might produce even more answers:

== Progress ? ==

So is there any further progress here? The proposal is old, it sneaked into an established state by now. As far as I understand there is no voting/approval process for restrictions, so these things go merely unnoticed.
By now the restrictions are widely used and understood by renderers, format converters (Garmin) and routing tools.
Nevertheless turning restrictions are still one of the things most annoying when missing (wrong in-car routing) and a pain in the a** if you have to edit them. So they are missing in a lot of places, as they seem to be to complicated (annoying?) to most mappers. The proposed changes could have brought a bit of ease, but as there is no official approval process, they were never voted on or anything (and they are not noticed now cause they only reside somewhere in the middle of the english discussion page).

As I am no veteran here, I would like to make a simple question: Do you (all the osm activists and full time mappers) think it is still possible to change anything about this relation? Or are these to widely used by now?
Do you think a new 'proposal' would be more of use then new discussion about changing the old one? Or do you even think all is fine with the turn restrictions and all problems should be solved in the editing tools?
I was writing a long summary of problems and possible solution here, but momentarily I think it might be futile and a waste of time. Do you think otherwise?

New history tab: Cool, but...

Posted by Chaos99 on 23 April 2009 in English.

Yeah, the new history tab is cool. I can see edits in my neighbourhood
and find people editing the same places.

But listing the edits is not quite of use by now.

All information you get is node/way/relation number and a bounding box. Which technically may be all you need, but for a human this data is useless. Mostly the bounding box is the only clue about what the person was edditing.

Would it be possible to highlight all eddited nodes/ways in the mini-map on the changeset page? To see what the edit was all about? Or, 'cause this is easier to implement, display the value of the name tag along with the node/way number (if present)?

This would really push this feature a lot.

picked my target

I improved my mapping equipment quite a bit by now.

First off I'm maping by bike now. And I don't meen the ones with the pedals.
I build myself a mount for my GPS device which I can see and use while driving.
The GPS tracks come off fine.

I mapped some small roads in Steinbach, put the whole village of Langenhain on the map (there wasn' even a place node) and added about a third of all residential roads in Waltershausen.

This all went fine. But I still lack a method of recording names and details. I have to either buy a action cam to mount on my helmet (which is nice for snowboarding too, but looks a bit funny out on the streets)
or use a voice recorder. The downpoint of the voice recorder would be that it is of no further use for me except osm mapping and is not quite inexpensive if you need a digital one with an external mic.

Has anyone experience in mapping by motorbike?

Additionally I set up a wiki page for mapping my district (http://wiki.openstreetmap.org/wiki/Landkreis_Gotha).
It's not quite ready yet, as I so far only copied the template and filled in the towns and villages. I still need to look into the existing details and set the status accordingly.

I also found osm mapper (www.itoworld.com), a nice tool to create rss feeds for special regions, tags or users.

I hope I can find help from local mappers to add more details to the maps.

Thank you

for the fast answers I get here just by posting diary entrys.

I got some answers within minutes by just barely hinting that I've got a problem.
What a wonderfull community.

Btw: Mapped two incoming and outgoing streets in the village of Steinbach in the forrests of Thuringia, Germany, where only a single node marked the village so far. No street names though.

Also mapped some footways in a park in Winterstein some kms north.

Edited this some 8h ago, allready visible in osmarender. wow

Own Garmin maps with mkgmap

Posted by Chaos99 on 5 February 2009 in English.

Just as a reminder to myself

1. get the date from OSM
curl -L "http://www.informationfreeway.org/api/
0.5/map?bbox=10.427293,50.856042,10.551697,50.927502" -o data.osm

The numbers beeing lower left and upper right corner

2. split up the file in case it is to big (the one I used isn't, but the programm generates a nice template option file for mkgmap too)

java -Xmx1000m -jar splitter.jar data.osm

3. process with mkgmap to produce .img file (and with this options an gmapsupp.img for USB upload to the Garmin)

java -Xmx512M -jar mkgmap.jar --latin1 -c template.args --gmapsupp

curl, splitter and mkgmap are linked somewhere in the wiki and are availiable for windows

Next: routing support (need to convert osm file into polish format, but didn't find a tool to do this)

cheers

Encountered tagging problems

Posted by Chaos99 on 4 February 2009 in English.

After my first mapping tour with more than just one street, I encountered some problems while adding the data to OSM.

Just tracing the gpx track in JOSM was pretty easy and worked fine and very intuitive.

The headache started while searching through the wiki to find the most appropriate tags to describe the information gathered. There are a lot of inconsistencies between the language versions (english and german in my case) between sites (Map_Features und HowTo_Map_A) and between the main page and the stuff written in the discussion page.

What worries me most is, that I was not searching for some misterious, golden paved woodway only for green firetrucks turning left, but instead for some simple streets in a small german village.

What I'm missing is a page similiar to the HowTo_Map_A page, which already is a great improvement to the Map_Features page, but with some more detailed description on the mapping and tagging process itself. What to look for in the field? How to distinguish between some features? What's best practise for those everyday rural streets?

Some concrete Problems:

- How to distinguis between tertiary and unclassified roads (in germany)?
- How to correctly tag the physical features of a road? tracktype/surface/smootheness?
- Is tracktype=* allowed for highway=residential, or only for highway=track?
- If a road touches a parking area (I can drive from the road onto the parking area at any point) can the way be the boarder of the parking area and the road at the same time?
- Does the noexit=yes tag belong to the last node of a way, or to the whole way?

I just have to say again, that I found more than one solution to these problems on the wiki pages. They are mostly mutual exclusive.

It's not in the spirit of OSM to tell people HOW to map and tag. Just to give them a way of sharing there data, I know. But a little more guidance would be very much appreciated. At least by me.

Mapping Tour in Winterstein

Posted by Chaos99 on 3 February 2009 in English.

Mein erster Versuch, mehr als nur eine Strasse zu korrigieren.

Das Oertchen Winterstein im thueringer Wald bestand bisher nur aus der durchgehenden Landstrasse und einem Ortsmittelpunkt. Jetzt sind so etwa 85% der Ortsstrassen vorhanden,

Jeweils mit Name und Bodenbeschaffenheit. Aufgrund der Witterung (Neuschnee), allzu misstrauischen Anwohnern und meiner Faulheit (ich war im PKW unterwegs) fehlen noch ein paar Strassen. Ensbesondere einige winzige Sackgassen, die nur Zufahrt zu einigen Haeusern sind.

Wird bei besserer Witterung nachgeholt. Versprochen.

Es bleibt uebrig die Frage, wie man Buswendeschleifen tagged....
