Seems nobody feels responsible here?
There is a highway=track connected to the motorway:
way/57745100
There is the typo highway=primary_link;abandoned on way/230135072

Hat sich noch leider nichts geändert.

Hi!
Please check typo
highway=unclassified; service on
way/642537041
Besides the wrong highway tag I am not sure what you wanted to do here. The highway is now a oneway and connected to a power line.

Hi! What is meant with highway=truck?
Was it a typo?
way/625763303

Hi!
Please use ford=yes to map fords. See ford=*

Thanks for the links. I've changed the tag to highway=pedestrian. I don't know yet whether to split the building or the pedestrian area. I think the building some kind of bridge here. I'll try to find out...

Hi! Maybe this is a shoal ? natural=shoal

Hi!
The tag highway=turning_loop is for nodes, not for ways. There are now to objects for the loop.
The node tagged as turning_circle should be changed to that and its location should be close to the tree. In that case the way should be removed.
Alternative is to remove the tag from the node, keep the way and change it to residential.
See also highway=turning_loop

Hi!
I think none of the ways here is a highway=bus_guideway. They are very special, see highway=bus_guideway

Welcome to OSM!
I've noticed this changeset because of this way:
way/375921541
It seems you have connected a highway with a waterway. Most of the old way was tagged highway=unclassified, that seems correct. If I got that right there is a waterway next to the road. Please draw a new way for that and unglue the waterways from the highway. What did you mean with highway=bus? That is very unusual.
Your goal should be to connect waterways so that they form a network.
Draw the way in the direction of the water flow.
Don't connect waterways and roads, they form separated networks.
Use Shift+V to run the validator, check the messages, they often help.
Hope this helps?

Hi!
Please explain where you got this strange data with lots of null values, e.g. amenity=null
barrier=null
brand=null
way/641881011
This looks like a bad import to me, was it discussed somewhere? See also
changeset/64262561

Hi!
I try to understand why you created a new route=pipeline relation here.
relation/8279171
Most of it repeats the information of the much older route relation relation/8279171
There is also one way that doesn't seem to be part of it:
way/123724670

Hi! I found this highway=yes and wonder if you meant service?
way/616154205

Hi!
Please try to fix the errors reported by JOSM before you upload the data, There are several ways with duplicated segments and duplicated nodes as well as duplicated objects, e,g. way/641972450 and way/641972482 both describe the same stairs, which probably should be mapped as highway=steps not stairs=yes

Hi!
I fixed a typo here, please check if I got it right:
changeset/64282446

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=*
