Sometimes it’s not clear why there is used the natural or landuse key. 

Landuse and natural tags have different keys, so that
you can have both; they describe different properties.
It's just that often or sometimes some landuse values 
virtually always imply some natural elements within that
area, so we don't even bother tagging them. E.g. 
farmland is just landuse=farm, without natural=wheat 
or similar, or a landuse=quarry is without 
natural=bedrock or similar.

For forrest you have both (landuse=forrest and natural=wood) but it seems to 
be the only one where you can decide whether it is managed or not.

The forest vs. wood is a bad example anyway, since
years back somebody made a mass edit and nobody
noticed back then that you can have an area used for 
forestry (landuse=forest), that doesn't have trees 
(natural=wood) in it for several years; when the area
has been clearcut / had a full chop recently. I.e. the
combination of tags is not redundant, which was the
only reason given for the changes back then. The 
original way was to use natural=wood with 
landuse=forest, or by itself; many still use them like 
that.

So, for the field borders, one could pick any or several
out of (at least) the following:
* natural=scrub
* natural=grassland
* landuse=meadow (meadows exist that aren't for
hay harvesting)
* natural=meadow

Even other tags may be suitable, depending on local 
ecological conditions.

Re: [Tagging] Feature Proposal - Voting - Port and terminals

2014-07-08 Thread Malcolm Herring
Most ports handle many different types of cargoes, so a single value is 
insufficient. It would be better to tag the individual terminal objects 
within a port with a type rather than assign a type to the port object.

We could use a single polygon per terminal tagged as in the proposal
(similar to other landuse types) if we need to go in detail. If needed
using also multiple values (http://wiki.openstreetmap.org/wiki/Semicolon)


If you read the page you will see that it pretty much says: DON'T USE 
SEMI-COLONS UNLESS THERE IS NOT OTHER OPTION.

mountain and hill, so this is subjective (you write it in the proposal)

2. The analysis of the other peaks in the area and the topography in

So this is probably not something we'd have to map manually, as it could be

Currently taginfo suggests almost no usage of peak like this

http://taginfo.openstreetmap.org/keys/peak#values


Yes, but that's exactly where the problem is: I think people are simply 
cheating now. =} They see no other peak tags in wiki, so they use just 
the one they see. Using natural=peak almost everywhere instead of 
man_made=peak, when that would be the most reasonable way to tag, make 
me think this way.



and see also:

http://taginfo.openstreetmap.org/tags/natural=peak#combinations


There's nothing interesting IMHO - name, ele etc. are all OK, but they 
don't help with the problem.



The Proposed_features page seems confused about tagging and
rendering though - given that local terrain height is available in
most parts of the world from external sources, couldn't a map that
wanted to suppress hillocks do so simply by comparing elevation with
that?  I'm not sure why you'd need to tag the height of things around
thing A on thing A itself.


I think tagging, documentation and rendering are somehow intertwined. 
That's why people are cheating. It's very tempting to have peak visible 
through natural=peak even if you know for sure it's not natural.


So let's look the other way: why we tag the mountain peaks, in the first 
place, if it's even more simple to identify them by comparing elevation 
than hills and hillocks?


Additional (general) problem is we have poor terrain representation. On 
the main page only the OpenCycleMap has this kind of data visible, but 
from what I saw it's effective only for high mountains. For micromapping 
it just doesn't work at all.



Also, the normal way to define OSM features is by going out and
mapping them - so I'd go out and do that first, rather than worry
about getting a proposal accepted.


I'm not that worried - if people won't accept it, it just won't be 
accepted and I can live with that: maybe I am totally wrong or that is 
not the best way of dealing with my problem? Go and tell me!


What worries me more is that I don't really know how to clearly show how 
complex this problem is. It's not only about tagging documentation, but 
also good elevation/shading background, tags rendering and people 
behavior. There may be even more! =}



start from here if I were you) but it's not meant to be - OSM needs
mappers far more than it needs proposal writers.  If you think that
it's important to classify a natural=peak as a hillock go and have a
look at it, and if it looks like a hillock to you, tag it as one!


Well, I am the active mapper for years now =} , but that's the wall I 
hit when micromapping and I try to fix it. I see this proposal as the 
next level of scratching my itch, not leaving the base work.

stay that way forever (public_transport=* namespace!).


If I was to define peak now, I would start with terrain=peak, and then 
add descent=natural or descent=artificial to narrow it down when

[Tagging] Track grades

2014-07-08 Thread Jesse Crawford
Apologies if this is the wrong list, I'm new to the community.

On the wiki talk page for tracktype [1] there is some discussion from
Australians of this property not properly reflecting road usability. Here
in desert New Mexico I am working on significantly improving mapping of
tracks, and I have the same problem. Many tracks here are apparently Grade
1 or 2 as they are made up of well-compacted gravel and exposed bedrock.
However, due to grade or unevenness they are often unsuitable (and unsafe)
for 2WD or low-clearance vehicles. These paths are often quite dangerous to
be stuck on, miles away from the nearest person and beyond phone reception.

It seems that there are properties to express information like evenness,
but they are not taken into account by the standard renderer while the
Grade is. Are there any plans to redefine Grade or create a new property
for use by renderers that directly expresses the usability of a road?

My suggestion would be adding a property (perhaps suitability) with
values of 2wd and 4wd, which matches the semantics used by e.g. Forest
Service maps which often show 4WD-only tracks with a different line.

As a second but similar question, off-highway vehicles are a popular
pasttime here and there are many tracks intended for ATVs or dirtbikes, not
wide enough for SUVs. Is there a best practice for tagging these types of
paths?

Thanks!

The combination of tracktype, surface and smoothness could fit the bill.
However smoothness values are ill-defined and would need more objective

I agree, man_made=mound isn't a bad idea.


Great, feel free to make such amendments!

My original proposition is rather wide, since I'm not familiar with many 
types of terrain objects and don't want to pretend I get the whole 
picture. Discussion about it learns me something.



I wouldn't question all peaks and require a subtag like
descent=natural for what can and has in the past sufficiently been
described with natual=peak. If there are a few mounds between the
currently tagged objects, you can always retag those few, but
retagging all peaks because there are some questionable ones between
them is not a good idea (IMHO).


I wrote about how it should be done right, while you talk about problems 
with changing what we have now, and that's a bit different question. I 
don't know how far we should go to make these whole terrain matters 
sane, but if we feel it really needs serious surgery, than the 
transition problems will arise inevitably. They are one of the main 
reasons why we have historical luggage at all (the other one is people 
getting used to some quirks).


If we would plan this transition, there are few possible strategies to 
take:


1. Convert all natural=peak into terrain=peak+descent=natural, 
because this is the most accurate and conservative tag translation.


2. Convert all natural=peak into terrain=peak and leave the 
descent key to be filled later, because we're not sure what the peak 
descent really is, as the natural namespace was already 
overloaded/abused (that is the strategy I would choose).


3. Don't convert anything, since we know this is important tag and a 
rendering implementation will lag - just add a new tag to the previous 
one. Then we could also overuse existing top-level natural=peak and 
man_made=peak instead of (IMHO better) lower-level descent=* key.


4. Convert all natural=peak into natural=terrain+terrain=peak and 
also define man_made=terrain or allow a little strange tagging: 
natural=terrain+terrain=peak+descent=artificial.


So we have many ways to resolve this. But I'm more interested in 
rethinking actual state of things as much, as it's possible, and only 
than think about how to make it technically. I know terrain in OSM is a 
broad topic, but I think it's time to touch it at least. Tagging it will 
be just the outcome of the choosing the right mental model.



I have tagged many of them with historic=tomb and tomb=tumulus (and
eventually also with building=tumulus) but they can also be considered
mounds.


Hm, not all the mounds are tombs.

You don't even realize how sad is this observation for me...

What is the role of writing documentation than - and approving it or

proposing and documenting?



renderer render and the cartographer style the map, and trust them to

You have no choice but to trust external rendering services - they will 
do what they think is important anyway. And we show this trust by OSM 
license.


But inside the project I think we need some more coherency. If there's 
an approved proposal with rendering hints, at least the default render 
should take it into account. Ideally I think all such features should be 
rendered - and if not, the documentation should be revised by rendering 
team explaining what is the problem. Eventually the consensus can be 
reached. Otherwise, if OSM is basically the GIS database, why the main 
project page has the map instead of big red Download the data! button?


In my case it was as simple as taking the template and filling it up. 
Rendering section in this template (and the field in the proposition 
infobox) means it's not unusual that the tagging can have rendering 
implications. And I see the difference in scale of peaks type, which 
should be properly visualised to not make default map cluttered with 
unnecessary details (like 
https://github.com/gravitystorm/openstreetmap-carto/issues/689 ). But I 
just gave rough idea - the rendering team may feel some other settings 
would be better.

2014-07-08 Thread David Bannon

Jesse, you are very welcome !

I have campaigned on this topic a couple of times but without really
achieving any consensus. Chief problem is some people's fear of
'subjectiveness'.

I don't really care exactly how it is done as long as we end up with a
clear model advising people whether or not they should attempt a
particular road. I have posted references to lost lives as a result of
bad decisions. Its easier to get people to take notice of simply
presented data. Too much detail scares most people 

My pet solution was based around tracktype= with two legs, (a) we
reassert that tracktype= applies to all highway=, not just
highway=track. This was the original intention. (b) extend the five
grades by another three, being 4wd recommended, required and extreme.

Another approach is to make wider use of 4wd_only=yes. Extend it to have
the 'recommended' and 'extreme' values. I was advised that tags starting
with a number were a problem in mapnik but others have dismissed that
and a new default render has taken over now.

I prefer the tracktype= model as it has pretty wide use world wide,
4wd_only= does not yet get much use outside of Australia.

 paths are often quite dangerous to be stuck on, miles away from the
 nearest person and beyond phone reception.
 
 
 It seems that there are properties to express information like
 evenness, but they are not taken into account by the standard renderer
 while the Grade is. Are there any plans to redefine Grade or create a
 new property for use by renderers that directly expresses the
 usability of a road?
 
 
 My suggestion would be adding a property (perhaps suitability) with
 values of 2wd and 4wd, which matches the semantics used by e.g.
 Forest Service maps which often show 4WD-only tracks with a different
 line.
 
 
 As a second but similar question, off-highway vehicles are a popular
 pasttime here and there are many tracks intended for ATVs or
 dirtbikes, not wide enough for SUVs. Is there a best practice for
 tagging these types of paths?
 
 
 Thanks!

Re: [Tagging] Feature Proposal - RFC - Enhancing natural=peak tag

Daniel, I don't know about standardization of rendering, but I would say
the advice on the wiki is followed by OSM mappers much more often than some
veterans think.

 You don't even realize how sad is this observation for me...

 What is the role of writing documentation than - and approving it or
 declining? You can always use the tags as you like it, and they will be
 rendered this way or another (or not a all), so why waste the time
 proposing and documenting?


  renderer render and the cartographer style the map, and trust them to
 understand tags of interest to them.


 You have no choice but to trust external rendering services - they will do
 what they think is important anyway. And we show this trust by OSM license.

 But inside the project I think we need some more coherency. If there's an
 approved proposal with rendering hints, at least the default render should
 take it into account. Ideally I think all such features should be rendered
 - and if not, the documentation should be revised by rendering team
 explaining what is the problem. Eventually the consensus can be reached.
 Otherwise, if OSM is basically the GIS database, why the main project page
 has the map instead of big red Download the data! button?

 In my case it was as simple as taking the template and filling it up.
 Rendering section in this template (and the field in the proposition
 infobox) means it's not unusual that the tagging can have rendering
 implications. And I see the difference in scale of peaks type, which should
 be properly visualised to not make default map cluttered with unnecessary
 details (like https://github.com/gravitystorm/openstreetmap-
 carto/issues/689 ). But I just gave rough idea - the rendering team may
 feel some other settings would be better.

Still there are some notable cases when they're not. I wouldn't be 
interested in rendering now if I didn't have my favorite problems with 
it lasting for months or years, even those easy to fix. That includes 
fountains and at least rudimentary public_transport namespace 
representation - these are just examples I personally need and it 
wouldn't hurt anyone.


I try not to be overly negative with it (no matter how irritated I feel 
sometimes as a mapper =} ) and go the positive way, so I get involved in 
openstreetmap-carto. It's just my beginnings there, so I'll wait some 
time before saying anything conclusive, but for now I'm very surprised 
how the low hanging fruit can be not picked for so long without anybody 
noticing it, even if all the code is already waiting to be merged ( 
https://github.com/gravitystorm/openstreetmap-carto/issues/705 ).


For me it tells us clearly that at least we should track such things 
better. If we made just a simple wiki table named Accepted propositions 
- rendering state with current comments from rendering team (done, 
todo - from when, wontfix - reasons, undecided - problems to be 
solved), it could help us connecting loose ends a lot! I can even do it 
myself, but I need to know it would be used at all. I don't know yet how 
big is the gap between default tagging and default rendering.


Yesterday I have watched Andy's workshop ( 
http://blog.gravitystorm.co.uk/2014/07/07/openstreetmap-carto-workshop/ 
) and while it was very interesting for me, the remark about the carto 
not being made for all the POI icons was against my intuition. I would 
fully agree if that meant simply there's more to rendering than POI's, 
but I'm not sure. I would rather include all such icons in general, 
because there was a reason somebody wrote it, a community consensus was 
established and it immediately promotes using such quality-approved 
tags. If we want to avoid the clutter (which is a noble aim in itself), 
don't try to avoid it altogether, but rather set the reasonable zoom 
threshold.


I hope these are things we can fix soon, but for now some visible 
problems are still unresolved.
