Hi mati-cl,
I see that you changed way/526879327 here, but I still don't see what it is.

Digital Globe seems to show a highway=track next to the rails. I assume this was meant with highway=yes?
If yes, draw the highway as an extra way.

Ok, please correct it and add a surface tag and remove the tag cycleway=yes..

Hi!
Please review typo highway=footpath on way/534238816
Is it a hw=path or hw=footway?

Ich seh das eher streng, kann aber damit leben ;-)

Hi and welcome to OSM!
I've noticed this changeset because you created a lot of short ways where the sat image shows one road. Please connect these parts. I think that this way way/534160181 can be reached with a car, so it is probably a highway=unclassified. You used name=carretera
I don't think that this is the name of the road, Please don't use the name tag to describe the object you are mapping.
Hope this helped and happy mapping!

Hi!
Please add / check the layer tags to the cycleway
way/25747077 between node/280779627 and node/3396499690.

Moin!
Bitte prüfen:
1) Tippfehler: Eine Zufahrt wird mit highway=service + service=driveway erfaßt:
way/533947934
2) Heißt das Ding wirklich genauso wie die L705 an der Stelle und wie diese Zufahrt:
way/109997787 ?
Etwas nördlich gibt es dann auch noch zwei hw=residential mit dem gleichen Namen.

Hi!
I've noticed this change because you used hghway=crossing for a way. Please review my corrections:
changeset/53146008

Hi Hermann!
I noticed that there are large residential areas in Vallée Du Zio. I wonder if this polygon is still up to date which would mean that all the buildings are in a hazard prone area.

Hi!
Please check: I've noticed this changeset because of the unusual tag highway=access.
Mapbox shows roads which look like highway=service to me.
This road is probably just a service=driveway without a name?
way/507644908
And this one probably is longer according to DigitalGlobe Standard Imagery:
way/435630077

Hi!
Sorry for this late comment:
I found nearly 3000 buildings with addr:street=Mkwajuni in this area
but no road with this name. What I found was this boundary:
relation/5525980
Do you agree that the addr:street tag is wrong here and should be removed?
The same problem exsts for other names in Dar es Salaam, e.g. Matokeo

Just noticed that you also removed name=Nelson Mandela Road, I fixed it here:
changeset/53121780

Hi!
Please review:
1) You changed a highway=primary to highway=Trunk. The correct value would be trunk
2) You removed oneway=yes from this road, I am pretty sure that it is a oneway road.
3) You added tags like Smooth=Good
or Smooth=Intermediate to some roads.
I assume you meant smoothness=good
/intermediate. Typically you only use lower case characters for the tag values.
See also smoothness=*#Smoothness
4) Are you sure that "Highway road" is the name of this road?
way/32741381
I don't think so. If you don't know the name, please don't invent one.
Hope this helps, happy mapping!
I have correct the trunk road here:
changeset/53121628

Hi
You added lots of buildings here which duplicated existing buildings.
I've reverted the change here:
changeset/53098833

Hi!
I've noticed this changeset because of the unusual tag highway=vehicletesting
which is only used in this area.
What do you think about changing it to highway=service + service=test_track.
This is used 30 times for similar roads and highway=service is rendered.
I assume all these roads should have access=private ?

Hi!
Please review:
Some roads in this area are mapped as highway="service road" instead of service and they are not connected to the other ways. They also have names like "dead end" or "Service Road" which seem to be fantasy names.
I also wonder if ways like way/127450076
should be mapped as path. The width seems to be ~4m. My understanding is that they are service roads to access the power towers/poles and that they are also used for hiking/cycling.

Please review my changes:
changeset/53090851

Moin!
Ich habe ein paar Korrekturen zu den Zebrastreifen gemacht, siehe
changeset/53088127

Hi Kurt,
your wiki page was recently changed to match this tagging, but I don't see where this was discussed. Some mappers in Germany (including myself) are very unhappy with this and you risk reverts by DWG. See also https://lists.openstreetmap.org/pipermail/imports/2017-October/005188.html
