[Tagging] Topographic place names
Hi all,
My cycletouring map, http://cycletour.org, has been slowly morphing into
a general topographic map[1]. One thing that's missing, though, is names
for topographic features like mountain ranges, spurs, and general areas.
Looking at http://wiki.openstreetmap.org/wiki/Category:En:Key:natural,
there seem to be some gaps.
- how do you tag a mountain range? That is, not a single ridge or mountain,
but a line of mountains, potentially hundreds or even thousands of
kilometres long
- how do you tag a spur? In Australia, many spurs are named, ("Champion
spur", "Son of a bitch spur"). natural=ridge perhaps?
- how do you name a generic geographic feature, like a cluster of rocks
("Mushroom rocks") or a vague features like "the blowhole", "something
hollow". The tags are all very specific and seem to imply the ability to
render it somehow other than using words. (I have ended up using
place=locality for some of these but it doesn't seem right.)

Yes please! I just added some hiking trails and had a named spur[1] that I
wanted to record. I used place=locality, but it seems wrong for the same
reasons you give. I'd suggest that since we have natural=peak, and
natural=saddle we should have natural=spur. natural=ridge, if it's not
already used, should be for ridges. Perhaps we could also have
natural=feature for a general named 'thing' that is visible and well known.
Could be any sort of rock, outcrop, fissure etc.

All sounds good. Note that for rocks and outcrops we do have tags:
http://wiki.openstreetmap.org/wiki/Tag:natural%3Dbare_rock
(I was using natural=rock before but it seems natural=bare_rock is
preferred since less ambiguous. I tend to use this for standing rock
areas as well as for flat ones...)

the question should be: how to map a mountain range, as it seems we can't
represent these kind of features (very big, blurry borders, not mappable in
high zoom levels) well in our data model. That's the main reason why we
don't have these. There are also other features similar to a mountain range
(a "forest" as name for a region, including non-forest areas, lowlands /
plains, desert, ...). Actually we don't have tags or a way to map to most
of these geographic features and regions besides the atomic components
(like peaks).
IMHO it would be nice to have an alternative dataset in lower zoomlevels
for geographic regions and extended/blurry features, something like a set
of shapefiles with translations into all languages we can provide,
something similar to what natural earth data provides, but distributed and
modified/translated by us, not just English and for higher zoom levels
(i.e. more detailed) than what NE has. Still we could start with their
geographic regions dataset and refine it, as "All versions of *Natural
Earth* raster + vector map data found on this website are in the public
domain."

if you don't know what it is (i.e. "generic feature") place=locality seems
perfectly fitting, otherwise be more precise and tag or subtag it as what
it is (e.g. a cluster of rocks).
Generally I see "natural" as the tag for a geographic features and
"landcover" for describing physical qualitities / vegetation.
