Any idea what went wrong? I guess you did not intend to produce these nodes.

Thanks for the feedback. There are still a few more:

Yes, OK. Next time watch out for the typo.

The picture shows lamps on the sidewalk and lamps on the major road. Still, they are all rather normal lamps, so I would map them as nodes.

Hi! You changed highway=track to the unusual highway=unsurfaced here
way/146708704
Was that intended?

Hi! Please check way way/643894897
I think you wanted to draw two single nodes instead?
You should also add the tag lit=yes to the corresponding stretch of way/560468809

Hi! I've corrected the typo highway=sevice here:
changeset/64475173
DigitalGlobe Premium Imagery shows connections way/508120219
Why didn't you map it that way?

Hi! What does highway=model mean?
The bridge is tagged highway=raceway, so I guess this should be used for the whole way?
way/643888711

Oops, forgot a link:
way/643087705

Hi!
You created some ways with the unusual highway=driveway instead of highway=service + service=driveway.
Was that intended?

Hi!
Your change created a lot of duplicated nodes in way/643344602
Similar problem here:
way/643369000
Did you disable the corresponding warning in JOSM?

I knew this project. From your comment I got the idea that you visited the place, so the source would be survey and not aerial image.

I think you should also remove the out-aged highway=ford key unless you know an app which still doesn't know ford=yes.

Hi! Would be good if ways like this would be connected to the road network:
way/213232382. Why didn't you do that?

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...
