I've just inserted a track (kirchgellersen - heiligenthal - oedeme) and found some...yeah I think it's the worst mapped area of OSM I've ever seen.
There are some streets, without a break (you know, when you're in the editor (potlatch) you click a street and only the part of the street that have the same name is selected and you can join streets then) and without a name.
It taked me ca. 10 minutes to identifie the streets with the help of some online maps...but I don't want to edit that I would try to ask the mapper who created this crap to give me his tracks, or to bring his work to an end.
The mapper uses the nick "tennet-ahertel" does someone know how I could contact him?

I may have misunderstood you here, but if you're saying that you used other online maps to "identify streets" then I hope you haven't copied names or other information from those other maps into OpenStreetMap without first checking that the license on those other maps allows such copying.

@TomH I use them to get the names of the street...I could take my bike and drive to the streets and read the names from the I don't see that there is a problem...(the online services don't have a copyright on the names...)

thx @Nic Roets

So drive down the streets on your bike and note the names down. It's what everybody else does (I hope). There is copyright on maps -- as I understand it copying a single street name is not a problem, but deriving some significant amount of our data from non-free maps (even if different people only add one name each) would be in conflict with copyright.

This should be explained very clearly in the wiki somewhere; unfortunately, I can't really find such a page...

Regarding the area you're complaining about, it just looks incompletely mapped, no?

@Detructor: If the street layout is not quite clear, I wouldn't rely 100% on an online map. I already encountered two streets in form of an "Y", where two longer streets were meeting in a short segment. Some online map named this short segment after one street while in the reality there was a sign with the name of the other street. Maybe an Easter egg in the online map?

@robx first comment:
I drive the streets and track them.
But sometimes I don't remember the name of the streets, can I get the name of the street in this case from google?

@robx 2nd comment: nope, the way that is mapped there consists of 2 or 3 ways.
If you go to the edit mode, you'll see that the mapper have a whole street made out of them.

@eumiro: hmm, ty for that...but at saturday I was in this area, because of a barbecue "party" with some friends...and I can say that google is correct there and the mapper have made a mistake

You can never, ever copy anything, at all from Google Maps - or any other map, unless it's a very old one (typically at least 70 years) and out-of-copyright. If you've forgotten the name of the streets, take better notes!

Or go back and resurvey the area. Quite often you need to back to an area a few times to be able to get all the information correctly into OSM.
