Hi!
I try to understand the situation around highway=unknwon: way/626122632
I think there is an amenity=parking, maybe for police cars only,which is described by way way/626121635
The way
way/626122394 is probably a footway, not a wall. The unknown way might be a wall or a footway or it is placed at the wrong location and it is a service road that gives access to the parking space next to the footway.
Just my thoughts, I am not a local, and BDOrtho is still too blurry.

Moin!
highway=track;path
Ist way/640616710 jetzt ein track oder ein path ;-)
Leider läßt Merkaartor anscheinend immer noch solche seltsamen Tags zu...

Moin!
Du hast hier versehentlich highway=indoor verwendet. Ich denke, du meintest indoor=yes, passen würde evtl. besser covered=yes.
Auf dem Luftbild sieht es so aus, als ob da drei überdachte Parkplätze sein könnten. Dann ist das building=yes way/182176782 auch ziemlich falsch.
Kenne mich vor Ort nicht aus, sind es drei building=roof oder building=garage?

Ich meine die Gebäude. Den highway=setr findet man nur als Information, wenn man danach sucht :-(

Moin!
Habe hier gerade einen highway=setr korrigiert und dabei diverse einige sich minimal überlappende Gebäude verbessert:
changeset/64159387
Hat JOSM das beim Upload bei Dir nicht angemeckert?

Das wäre dann aber ein grober Fehler in Go Map!
Abgesehen davon fehlen auch noch die Tags für den Tunnel: tunnel=yes + layer=-1

Hi! What does it mean when you change a highway=pedestrian to highway=roof like here way/613816426 ?
Maybe you meant to use covered=yes? Or maybe it is a building=roof?

Hi! Please check way way/640420336
I guess you wanted to add the tag highway=give_way to a node on it?

That was quick :)

Moin!
Do hast hier einen Weg mit highway=foot angelegt. Meintest wohl footway. Ich frage mich allerdings, ob der Sinn macht, weil er im Nichts endet. Kenne mich vor Ort nicht aus, ich würde lieber das passende Tag sidewalk=* an die Barbarossastraße hängen. Siehe
osm.wiki/DE:Key:sidewalk

Hi and welcome to OSM!
I've noticed this changeset because you used the unusual tag highway=closed:secondary here: way/640269557
The correct tagging for a closed road would be disused:highway=secondary, see osm.wiki/Lifecycle_prefix
If the road is closed for construction you can also use highway=construction + construction=secondary
I wonder why you split the road. The remaining part is not connected to anything else, so it is probably also closed?

Hi! I contact you because you changed a way tagged highway=byway.
This tag is deprecated, please change it when you edit those ways. See osm.wiki/Tag%3Ahighway%3Dbyway

Hi!
I've noticed this changeset because of typo highway=Alameda 2
on way/153514990.
IBGE shows two different spellings for the name: "Alameda 2" and "Alameda Dois"
Is it okay when I always prefer the first variant? I ask because there is no "Alameda 5", only a "Alameda Cinco". This leads me to the next probem :
According to IBGE this way should be split:
way/153514977
and partly renamed. Guess you are working on that?

Moin Frank,
neh, ich bin ein Sesselmapper aus Wildeshausen.

Yes, that would be nice.

Hi! I contact you because you changed the coastline. I wonder why this island is natural=coastline:
way/2961222
The way way/35834999
passes it in the north, so it is part of the main island, not in the ocean. I don't know if I should remove the tag natural=coastline from the island or if I should modify the said way so that it passes the island in the south.

Hi!
You used natural=coastline here but the island is in IJmeer, a natural=water.
See natural=coastline
I've removed the tag here:
changeset/64118632
Please check if you find a better tag, else those ways might be removed again.

Hi!
You used natural=coastline here but the Markermeer is a natural=water.
relation/49368
See natural=coastline

Hi!
I just remove a wrong natural=coastline here, don't know what it really is:
way/522081035
Maybe you remember?

I did that quite often now, esp. here:
changeset/64115009
Hope I did not change something good.
