In effect, it can be seen as "features that should appear on a nautical
map".  A seamap rendered output will
emphasize, or mostly use, seamark features.  The convention for seamark is
to dual tag when the feature
has both a seamark and a mainline osm tag.

I think the general concencus is that waterway=fairway is a useful tag. 
I'll just add it to the wiki so people will know about it.
I'm also going to change the waterway=lake to waterway=fairway where I 
come across it and think it should be changed.

Maarten

Hi Maarten,

> I'm seeing some ways tagged with waterway=fairway in the Netherlands. 

I did this to mark fairways on lakes in simple way and to draw a navigable
inland watrways network. These waterways should also have tags like
motorboat=yes or CEMT=* to classify.

Results can be seen on

http://maps.grade.de
and
http://routino.grade.de

> This user also added waterway=lake on unclosed ways.

Must have been a mistake if tagged by me

Have a nice day, Dirk

you do it for some features, but not for others. e.g. "landmarks",
http://wiki.openstreetmap.org/wiki/Seamarks/INT-1_Section_E
e.g.
seamark:type=landmark
seamark:landmark:category=tower

wouldn't this be better represented as man_made=tower, landmark=tower (or
yes)?

similarly, all the contained objects in landmark already have their
corresponding tagging (or should get it):
seamark:type=landmark
seamark:landmark:category=monument
(or seamark:landmark:category=column)
(or seamark:landmark:category=obelisk)
(or seamark:landmark:category=statue) Monument, column, pillar, obelisk,
statue
...



Also in this section, there is a draft which seems that someone wants to
add more information in the future (empty tables), where my suggestion
would be to either add a short sentence why there is no information, or
whether you plan to add more (or encourage people to add it) or to remove
these paragraphs (with currently no information, and where "normal" tags
are there or should be invented, like "public buildings", port
infrastructure, etc.):
http://wiki.openstreetmap.org/wiki/Seamarks/INT-1_Section_F


And a lot of features from here
http://wiki.openstreetmap.org/wiki/Seamarks/INT-1_Section_U
seamark:type=harbour
seamark:harbour:category=marina  (doesn't seem to add anything compared to
leisure=marina)


seamark:type=small_craft_facility
seamark:small_craft_facility:category=restaurant   (or is this for
restaurants that can only be accessed with small water craft and not e.g.
by pedestrians?)

seamark:type=small_craft_facility
seamark:small_craft_facility:category=telephone



cheers,
Martin

Indeed we do encourage the usage of mainstream OSM tags for all natural 
& cultural/manmade objects. Where seamark tags are added to these 
objects, it should be only to indicate additional navigational information.

I'm not sure we are stuck with it. Like other ill-fitting tag names we
should try to fix it.
A very small change and replacing "rk" with "p" would already be an
improvement ("seamap:*"), but on a more general note I think that
everything that isn't only occuring in seamap contest should likely get a
"normal" tag (e.g. "rock", bridge, ...) in the more common natural,
waterway, man_made etc. namespaces.

Martin

This is historical. At the beginning of nautical navigation mapping, it 
was buoys, beacons, lights, etc that were being mapped. As is usual with 
OSM mapping, feature creep set in to include all objects listed in the 
IHO catalogue. In retrospect, a broader term than "seamark" would have 
been better, but like many other ill-fitting tag keys, we are stuck with it.

I know this has been discussed before, but as the issue persists, I'm
mentioning it again: why "seamark:*"? Are there any plans to transition
from "seamark:*" to different tag names that are more descriptive, for
things that aren't "seamarks"? If I read a tag "seamark:type" I would
expect this to describe a seamark, not a nautical channel.

Cheers,
Martin

How are nautical channels ("fairways") tagged of OpenSeaMap. I could not
find out at first glance, but they for sure must have same tags for that.

[Tagging] waterway=fairway?

[Maarten Deen]

I'm seeing some ways tagged with waterway=fairway in the Netherlands. 
Some examples:

https://www.openstreetmap.org/way/215071961
https://www.openstreetmap.org/way/210382535
https://www.openstreetmap.org/way/215071958

These examples have all been added in 
https://www.openstreetmap.org/changeset/15581966, there are more 
examples in the changeset.


Taginfo: 
http://taginfo.openstreetmap.org/tags/?key=waterway=fairway


This user also added waterway=lake on unclosed ways.

Both waterway=fairway and waterway=lake are not described in the wiki. I 
do get the idea of waterway=fairway. This user seems to have added this 
in lakes to indicate the navigatable route. Since these lakes are 
shallow, there are predeterminded routes marked by buoys. So it makes 
sense.

The waterway=lake I don't get.

What is the thought on this. Is this something to keep or should these 
routes be tagged as waterway=canal? These are not canals, so I do see 
the added value of using a different tag. Is fairway an acceptable one? 
Fairway does seem to be the english term for this feature.
Should this be up for for vote as a proposed feature of should we just 
add it to the waterway wikipage?

Maarten
