osm.org/way/803547358 and other ways with waterway=tidal_channel in this area are incorrect. A tidal channel is only found by the sea, where there are tides.

osm.org/way/814406463 no es una waterway=tidal_channel por que no es cerca del mar. Quisas es una waterway=stream?

osm.org/way/817795994 is tagged as waterway=tidal_channel, but that’s not right. Is it a stream or river perhaps?

Hi Закат, Sorry of the bad translation:

Водные пути здесь не являются «приливными каналами», потому что эта территория находится на высоте около 100 метров над уровнем моря. Приливный канал находится рядом с океаном на уровне моря. Возможно, их следует нанести на карту как ручей или реку, в зависимости от их ширины.

osm.org/way/848680092

The waterways here are not "tidal channels" because this area is about 100 meters elevation. A tidal channel is found next to the ocean, at sea level. Perhaps they should be mapped as a stream or river, depending on how wide they are.

Hi, I notice that you added the tag waterway=tidal_channel to osm.org/way/826215274 - but that tag is for tidal creeks or inlets next to the sea. Perhaps this is really part of the lake?

Hi, I noticed you used the tag waterway=tidal_channel for osm.org/way/790436540 - but this seems pretty far away from the great lakes. Are you sure this is a tidal channel, not a stream or canal or ditch?

I would recommend following the guidelines at osm.wiki/Indonesian_Tagging_Guidelines#Roads - the Indonesian language version might be more up-to-date but this English version is pretty good.

Re: the Jalan Trans-Papua system, while it isn't complete, a list of the segments under construction is mostly correct on wikipedia: https://en.wikipedia.org/wiki/Trans-Papua_Highway - there are 3 segments which end in Wamena.

According to the tagging standards used in Indonesia, the Jalan Trans-Papua should be highway=trunk when the segments are finished between cities (that is, as soon as you can actually travel from Wamena to Jayapura, or Wamena to Nabire). Right now they are tagged highway=primary, except for the completed section between the cities of Sorong and Manokwari in West Papua. But if you look at the Jalan Trans-Sulawesi network in the island of Sulawesi, you can see what is will look like in a couple of years.
This article has a somewhat-accurate map: https://www.batasnegeri.com/jalan-trans-papua-untuk-anak-cucu-papua/ (Indonesian) or also see this: http://papuanews.org/trans-papua-strengthening-the-connection/

I would recommend checking the Indonesian tagging standards in this document: osm.wiki/Indonesian_Tagging_Guidelines#Roads

Generally all parts of the Jalan Trans-Papua should be highway=trunk once they are completed (though most are still under construction). Other main roads which connect different Kabupaten (Regencies, admin_level=5 administrative areas) are highway=primary, or the main roads through towns and cities. Then highway=secondary connects districts (kecematan) to towns and other districts (kecematan), while highway=tertiary connects villages (desa) or suburbs (kelurahan) to other desa and kelurahan, or to a larger town. The tag highway=unclassified is only used for a "road [which] connects activity centers in rural areas and is an interconnection between two small hamlets (dusun) or neighborhoods or between a hamlet and isolated farms or houses."
In Eastern Indoneisa, especially Papua, any of these might be unpaved (except for highway=trunk) in rural areas, though highway=primary should be mostly paved, and will almost always be paved in towns. A highway=secondary or highway=tertiary will often only be 1 lane wide (4 meters) if it is paved, and most are unpaved outside of towns.

Good idea, I've done this now.

Oh, perhaps facebook mappers added those incorrectly as roads when they came through here last year.

Note that highway=path is normally legally allowed to be accessed by motorcycles in eastern Indonesia (though it may not always be physically feasible, if there are narrow bridges or ladders in the way).

> Re: " there are some features that look like volcanoes but aren't, like Spencer Butte in Eugene, while other features, look like volcanoes and are like Kelly Butte in Portland."

How are we to tell them apart, aside from digging in the ground or digging in a library? This is good data for Wikipedia or Wikidata, which rely on citations, but not for OpenStreetMap, which relies on primary research: survey of the location.

"Taken literally the lack of a crater indicates, in Oregon, that Mt. Jefferson and Black Butte aren't volcanoes:

Mt Jefferson does not appear to have an active volcanic vent at the summit. The peak is an eroded remnant, below the old crater which was destoryed by glaciers in the last ice age, if I've read correctly. So I agree that it should be mapped as natural=peak. There might still be semi-active volcanic vents along its flanks that can be mapped as natural=volcano.

Recall that natural=volcano is not a tag for topographic high points (peaks), but for vents in a volcano. If the point is set on the peak of a hill or mountain, it is likely that we are mapping a natural=peak, not the vent of a volcano, though in some cases (lava domes) the peak and vent might be nearly in the same place, that's rare.

It's not necessary to have a crater, but there should be on-the-ground evidence of an active or dormant vent: a lava dome, a crater, a lava plug, a caldera, fumaroles, etc. - otherwise it is just a hill or mountain which happens to have been formed by volcanism in the pre-historic past. Such information cannot be verified, so it's not much help adding it to Openstreetmap.

Currently there are construction materials and equipment visible in Bing (and Maxar and ESRI) imagery, but no bridge structure. Perhaps it is still under construction?

These are not tracks. They are paths. You can't drive any sort of 2-track vehicle on them.

Tracks are rare in Papua, especially near villages. They are generally only found in forested and plantation areas.

In this changeset you connected Jalan Jawa (way 301495902: osm.org/way/301495902) to way 597206758 (osm.org/way/597206758),

But there is a fence between these. I know because I tried to ride my bike this way once. You can sort of see the fence / wall in aerial imagery. Please don't connect streets unless you are certain that they are actually connected.

Why did you reduce the classification of this road to highway=unclassified instead of tertiary?

Notice that this disconnected the highway=tertiary to the east (in Pugima) from the rest of the tertiary and secondary network!

Why did you change the classification of ways in this changeset? Do you have any local knowledge of Papua, Indonesia? What standards are you using to decide if a road should be =trunk, =primary, or =secondary?

If you read Indonesian, have you read the documentation from users in this country?

Hey, you added a bridge here, but I don't see it in the Maxar imagery, only a ford. Can you confirm that way 800498700 is actually a bridge? Where did you see this?

Why would you change the main road to unclassified? It's the only road in the whole area, and it's part of the Jalan Trans-Papua system which will eventually link to the road under construction 40 km to the north.

Highway=unclassified should only be used for the most minor roads which connect a farm or a few houses to the next hamlet.

Why did you change these roads to unclassified?

Jalan Trikora is the main shopping street in town. It's 2 lanes wide and paved the whole way, which is quite high quality for Indonesia.

I'm a local, btw.

Why did you change this section of the Jalan TransPapua to Secondary?

By convention, the "Trans-[Pulau]" highways are trunk or primary, e.g. Jalan Trans-Sumatra, Jalan Trans-Sulawesi, Jalan Trans-Papua.

Certainly the road into Wamena should be Primary: if you see the Y at Wosi, the route to Wamena is busiest and widest.
