Actually it ends at 61° N, with the last 1° block starting at 60° N. For some
reason the cylce map no longer uses that last block.
And it's eventually way too scarse.
Right.

They can't be auto-generated from gridded DEMs. Consider these
What data source are you suggesting that the renderer should use, if not the
OSM database?
The same one that the cycle map layer uses to draw contour lines.

Hello,

I think it's easier to survey a ridge (either from aerials, or by
walking along it with GPS) than to get enough altitude points to
generate it automatically, so I think we should allow them to be
entered as ways (which won't prevent renderers from

I am not sure for the wording though. Isn't this an edge? Maybe I am
confused, because wikipedia told me that a ridge would be a natural
feature (your proposal doesn't give any definition what a ridge is)
occuring at a _chain of mountains_
Martin,
Ridge IMO closest means Kamm in German.
eg. Nordkette north of Innsbruck

- we should distinguish this from -
a whole mountain range (das Gebirge in German)

yes, I'd also see it like this. So how would you tag a de:Grat? natural=edge?

Hi Martin,

Yes, that's unambigous, but what about this?
Thanks, that's what I tried .

I would consider both a ridge. But honestly my personal definition would be
to the German Grat...:-) To give a negative example, here something I
would not consider a ridge but either cliff or rock:

Don't know what the correct English phrase would be. Maybe the mountain guys
@talk-at know... User fkv/0/ has done a lot of mountain edits, AFAICT.
BTW, should also be discussed rendering-wise, comparing a cliff

There are peaks that can be tagged properly (although it's technically
possible to deduct them with some accuracy from elevation maps), but
