Hi!
This changeset created invalid tags like highway=unclassified;tertiary
name=Camin dels Prats Grands;Chemin Toulze
and added ref=D 18.
I've reverted it here: changeset/64282381
No idea what you wanted to map.

Hi!
This looks like a bad import to me. What does it mean when you add a way with 59 tags and most of them have the value null?
e.g. way/641882590
Please revert or let me know if you need help with that.

Hi! I've noticed that you map buildings at the position of the roof in the aerial image. This doesn't work well for high buildings, e.g. way/638502221
Please try to estimate the position on the ground. See also osm.wiki/Buildings#How_to_map

Ja, sorry, hatte den Link vergessen:
way/38804490

Hi Karl,
the value boardwalk has no meaning in OSM. Please check highway=*
to find out more. You can find a list of your changesets by clicking on your user name or use this link @Ipswichkarl

Moin!
Ich frage mich gerade, wie der Pfad way/51732243
ein Teil der WEDAL Pipeline sein kann.
Sieht nach einem Versehen aus.
relation/8197801

Hi!
You changed a man_made=pipeline to highway=secondary here. If I got that right there is a road next to the pipeline and you should have created a new way for that road.

I found a lot of unconnected roads in this area, most of them created by you. It seems that iD doesn't warn you when you create a new road that crosses other roads without a connection?
I've corrected many problems here:
changeset/64253905
changeset/64254070

Hi!
I wonder why you did not connect the ends of the bus_guide ways like this way/641631549
This is a very special kind of road, please check highway=bus_guideway
to make sure that you used the right tagging.

Hi and welcome to OSM!
The tag highway=boardwalk is only used here, why did you change highway=footway?

OK, thanks for the feedback :-)

Ah, I see. Whenever the wiki shows a highway=* that means that you should replace the * by a meaningful value. Not only with highway, this is always true.
I see no need to map the area, esp. not when you alse map the node with highway=turning_circle

Thanks Sean,
I'll change the island tomorrow. On some other similar objects I simply changed the natural tag to was:natural=coastline, that should be OK for this one as well.

I've only read the comments in the thread after you mentioned the TAP. I think nobody agreed with you in those comments.
See e.g. http://gis.19327.n8.nabble.com/How-to-tag-named-group-of-named-water-areas-tp5923692p5926559.html
I've just loaded all relations with route=pipeline. They have a total of 4119 way members, 3667 of them have the man_made=pipeline tag, most of those ways which are not tagged man_made=pipeline are in fact not pipelines but waterways, fences , highways, piers , you name it. In other words, quite a lot of garbage.
A consumer cannot simply assume that all members are pipelines.
Now, guess what happens when you remove the tags from the ways which describe what it is.

Hi Dave,
I think each type of relation has its own rules. You cannot simply transfer the rules for multipolygons. Example: In mp rels the order of the members doesn't matter, in hiking relations it is important. In mp rels also the roles do not really matter because consumere programs don't need them, they are only important for the mappers. In other relation types the roles are very important. In case of route=pipeline rels
there are not many documented rules because they are not important to many users. If you want to establish a new tagging system for pipelines you have a good chance, you just have to convince those who are interested. I am not one of them, I just try to convince you that you should not start to do your own thing just because it looks better to you. You simply risk that someone reverts your work
when you act against common rules.

Reg. Iditarod Trail: If you want to remove the name tags from the ways I say that is good. These ways probably have no name, they are just part of a route.
I did something like that, see this discussion:
changeset/13576057

Hi!
The tag highway=turning_loop should not be used on ways, use it only on nodes where you don't want to draw the loop itself:
way/640722514
Think it is a highway=path? Isn't this area
way/640722522 part of the park
way/80798482 ?

Thanks for the quick feedback. I think highway=path ist best then. If you like you can add bridge:material=wood.
You should not use highway=residential for ways which are too narrow for normal cars.
Why do you add the tag import=yes here?

Hallo und willkomment bei OSM!
Du hast hier ein paar Fußwege mit dem tag sidewalk erfaßt. Im Normalfall werden solche Wege gar nicht extra gemalt. Stattdessen gehört an die Straße das tag sidewalk=both.
Falls doch eigene Wege notwendig sind, dann bekoomen die das tag footway=sidewalk bzw. footway=crossing. Das ist meist deutlich aufwändger und feheranfälliger, weil man alle Verbindungen zu anderen Straßen erfassen muss. Siehe auch osm.wiki/DE:Key:sidewalk
Dann gibt es da noch den highway=turning_circle. Das hattest Du mehrere Wege übereinander gemalt. Ich habe das mal geändert, so wie es normalerweise erfaßt wird:
changeset/64220585
Der Weg way/640909059 ist wahrscheinlich auch highway=residential, evtl. auch nur highway=service.
Zum Schluss das wichtigste: Wege mit dem highway tag sollten immer mit dem Rest des Straßennetzes verbunden werden.JOSM macht das normalerweise ganz automatisch, wenn Du einen Weg zeichnest. Falls nicht, dann wähle den Knoten aus und drücke N, um ihn mit der nächsten Straße zu verbinden, oder M, um ihn mit einem schon vorhandenen Knoten zu verschmelzen.
Bevor Du die Daten zu OSM hochlädst solltest Du mit Shift+V die Überprüfung starten und dann die gemeldeten Feher bzw. Warnungen korrigieren.
Wenn Du Daten änderst oder hinzufügst, dann bitte immer erst die vorhandenen Daten runterladen, sonst produzierst Du wie hier doppelte Wege.
Hier ist noch mal ein Link zur generellen Anleitung:
osm.wiki/JOSM/Guide
Ich hoffe, das hilft Dir, die Daten zu korrigieren, so daß auch Router damit was anfangen können. Viel Spaß beim Mappen!

Hi! Please don't use the tag highway=traffic_calming. I've removed it here:changeset/64220325
The tag traffic_calming=island is normally only used on nodes. I think you may use landuse=grass for these two. Or maybe remove them because of the natural=tree_row ways.
