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.

Hi! I just changed some ways imported by you where island / islet in fresh water where tagged with natural=coastline. Please check
natural=coastline
before using this tag again.
See e.g. here changeset/64114025

Thanks, I am concentrating on errors in the coastline, just wondered why it is so difficult to the sat images in this areas.
I guess correcting would require some knowledge about tidal changes etc, so nothing I want to do.

Google Maps is not a source we can use.

Hi!
I just stumbled over this natural=water way/410411380
You used landsat as source, Bing and others show the coastline at a very different position. Do you think landsat is up to date?

Hi!
You changed the coastline here in a strange way. Many islands like this
way/584475336
are tagged with natural=coastline and a few days later you created way/585223066
so that all the islands are no longer in the sea.I've removed the natural=coastline tag from those islands, see here:
changeset/64108991

Hi again!
It seems you broke a lot of water multipolygons in this area. What was the reason for the changes?
relation/4133247
relation/4133245
relation/4272563

Hi! You added the tag natural=coastline to some ways here. The ways are inside a natural=water polygon also mapped by you, so I wonder what you did. Please check
natural=coastline
and review my changes:
changeset/64107152

Hi!
I've removed the natural=coastline tag from two ways, see changeset/64105566

Hi!
Please check: You changed a natural=water multipolygon to a aeroway=aerodrome.
The Lake Hood is no longer in the map now.
Is the lake also the Lake Hood Sea Plane Base?
