Bin ganz neu und völlig begeistert, habe meinen Heimatort Obereip und Umgebung begonnen. Da war noch nix. Hat nach dem ersten Rendern nicht alles so ausgesehen, wie es sein sollte, aber das wird noch...
Vielleicht kann mir jemand sagen, wieso aus dem Wohmbach so ein Riesenstausee geworden ist?
Außerdem habe ich mir die routable map für mein Garmin installiert und bin schlichtweg hin und weg. Dafür, daß diese maps noch als experimentell ausgewiesen sind, klappen sie sehr gut!

Added Allenton near Oldcourt/Bohernabreena.

Added St Annes GAA and cemetery.

Thats about the last area of virgin territory in Firhouse/Ballycullen/Ballycragh area I was planning to do initial surveys of!

Now all the roads and major areas are in the map, I can go back and add missing road names and other POIs.

Success story:
The other day I had to pick up my girlfriend from work. Since we just moved here recently I wasn't too sure about the quickest way. Out came my Etrex Legend and thanks to OSM and http://emexes.powweb.com/osm/ I was routed to my girlfriends work just fine and as I was later told, on the fastest way possible. This is awesome.

Thank you all for contributing to OSM.

I could really use some advice on rivers. I've been trying to fix the Potomac River in Washington, DC, and failed at three attempts so far.

FWIW, I've got several different things going on in there right now to see what renders correctly next week.

natural:coastline seems to be the cheapest, but a total cop out for rivers.

The linked, proposed method descriped in the map features wiki just doesn't seem to work at all.

Several times I saw changes when suddenly a "created_by"="Potlach" appeared. Many of these changes were wrong and I often accused Potlach of being the one to blame. But I was wrong: The default audience of Potlach is to blame. Don't get me wrong: I don't say everyone who uses Potlach will only make mistakes! But some things should really not happen. Let's take an example:

I got the city boundaries for Koblenz from an official department. I added them 2 days ago and today I found out that someone moved one of them. It does not make any sense. I doubt it was done intentional. But it happend.

Also many things are done based on yahoo images (or however this is called). This is great for forests, railways and straigt wide streets ... but not for complicated crossings. Take a look at: osm.org/?lat=50.38497&lon=7.56143&zoom=17&layers=B00FTF
This is the most complex crossing/link I know of. And someone worked on it based on the images ... using Potlach ... completely wrong. I avoided doing it (until few days ago) using JOSM for a while since I know this place very well and it is just to complicated. By the way (at least I think so) the user several dozen of kilometers of the street of being a bridge ... which was wrong, too.

So I wonder if there is anything we can do to help Potlach users. I can think of 3 things that really help me in JOSM:
* The validator plugin. It fetches a lot of mess I create before I upload it.
* Bridges recently got a "blue overlay" in JOSM. This really helped me to see where I did bridges and helped me rethink a few of it.
* Explicit saving. In JOSM you need to upload your changes by clicking a button. I really like to see a "Save" button in Potlach so an average user can do as much as he/she likes without actually destroying things.

If I got anything incorrect feel free to correct me. This is just my (currently a it frustrated) point of view.

Thanks for reading :-D

I figured id write it in here, in case anyone can chime in.

I am working on the outline map, and using xapi to grab the large amount of data. .. as an OSM file, these files are big, however, when i convert them to IMG files. .there smaller. Considerably smaller, in that its possible to have all OSM data for Canada in a complete Canada mapset.
What im doing is creating a set defines tile area, in which the boundaries don't get messed up with too much overlap of data. .. trying to make it so that full city areas are all in the same tile region, and so its only a few road segments which might get duplicated.

Cloudemade: I see that it hasn't yet been organized, as a few downloads for IMG tiles. .. thats probably because of the sheer scale of it.
So when small isolated towns in the north (for example) yet OSM'd then it takes a whole lot of power to get all that data and converted again.

What would be wild is this:

Using Marble Desktop, to be able to grad the area your looking at, and save it as an OSM file. .. or better yet. with a extra couple mouse clicks, to have it automatically run mkgmap program in DOS, as the file just needs to be saved as data.osm, and it automatically gets saved as the same #'d tile. .. so ....
What would be cool would be to have a program where it automatically asks me to save that .img file SaveAs then i would change the name.

Is there an international standard for tile numbering? .. for GeoBase it seems pretty good, as I'm using 72 as the prefix as it corresponds to 'G' 'B' and then 2 3 digit tile areas. .. if the planet is divided into squares from the equator to the poles. .. cant we have a '1' for possitive and a '0' for negative ..
so then when describing the tile, its 10490123 .. meaning positive 049N and negative 123W .... so then we can have 1 degree tiles available all over the planet. with 1 mouse click to grab the osm data and convert it to IMG.

Wednesday and so Mapnik did his thing once more. Finally I get to see what my multipolygon really looks like and if you're going to have a look you will see some errors. In some zoom levels a line is dividing the whole thing and in another you'll see a weird square, but... I think I solved it: I found that some segments of the outer closed way were doubled. I was able to locate and delete them without destroying the whole thing. Strangely enough it didn't work at first, it just got back after I switched briefly to the view tab and back (Yes, I deselected it first), but after I first removed all the tags and then went deleting the way's, it did stick.

By the way: in Kosmos it all looked fine, so also there's no 100% proof of what Mapnik is going to make of it in the end.

In Hilversum some road works finished a month or two ago, they added two roundabouts and changed the flow of traffic slightly in other points. I had my OSMTracker running whilst driving along those roundabouts yesterday evening and I'm planning on correcting them, but they're not of you're average run-of-the-mill type roundabouts. At some points they have 2 lanes, one for turning right and one for driving along for one quarter more. Of course some future navigation freeware has to be able to make heads or tails of it.

This map making thing is not as easy as you would think at first glance. Just the myriade of tags alone is dizzying. No wonder there is a constant debate about them going on. And so many people working on it all with their own idea's about how to do things in OSM. And of course everybody's right too. Only problem is, you'll at some point have to make a decision and that's tough, because most idea's will be cast aside and only one will survive and everybody want it to be his/hers of course.
