Was this an import? You plopped down 2000 untagged nodes in this changeset - following highways that you had edited, and then 2 thousand more untagged nodes on top of those in changeset/91233339.
A JOSM hiccup maybe? I'm deleting some and trying to reuse most of them - but still a lot there!

No motorways here!
Pas d'autoroutes ici!

Hey Daniel - Just so you know, you want to tag highway construction as
highway=construction
construction=<highway class>
What you've mapped won't render as U/C for most data consumers! :)
Really happy you know how to map arterials! Too many in HOT don't! Cheers...

Looks like we were editing the same area...

I don't intend to mislead you - so I'll confess that I am NOT local to Mali. I'm armchair mapping from the US.

It's okay! We're obviously on the same page mentally. Love the work you've done on Bamako - it certainly has needed it.
I've been placing settlement names throughout Kati and Koulikoro cercles, but I don't have good data for Bamako city, so I'm largely leaving it alone.

Salut!
re: node/1051051796 node/1051051796
This is a crash SITE from 1983 - if there is a memorial there, fine - but I'm not on the ground to confirm that. But I think the "ruins" can be removed without a ground survey. Would you agree?

Salut! Please do not create place names with all CAPITAL LETTERS. First letter of each word capitalized - that is all.
DIALAYA -> non
Dialaya -> oui
Merçi!

And another note - to everyone here. I've found boundaries in Mali imported from maplibrary.org that are absolute junk.
I've come to the assumption that anything imported from that source is automatically suspect (at best), automatically false at worst.

@Richū I have seen some very talented and knowledgeable mappers kicked out of OSM because of attitudes like yours. Please understand that OSM is a "best effort" project - if an edit isn't perfect, you try to improve on the effort, not automatically delete or revert.
Everyone in this thread has the same goal - to get it right. But in the OSM world, that goal is a way, not just a node.
(Nice metaphor, eh?)

Sorry, to be clear - I meant deleting the buildings that are not in the more current imagery. The next project for the area will be a building mapping project for beginners.

Just so you know, the project did not include mapping of buildings, and MAXAR imagery was being used. You mapped buildings to out of date Bing imagery - do you want to fix it or have me delete the buildings?

Why are you merging "place" nodes into highways?

I see what you mean - Monzombala

Okay - I believe it should be good now

The unconnected intersections are from the way moving from its former position

Not sure what happened exactly, but the entirety of way/853247752 got moved about 60-70 meters north in this change. I'm fixing it - just thought you should know.

@cRaIgalLAn @ftcat @rab @Ruben Morgado
Would love to hear your feedback.
I have more to add on the Malawi side, but will leave it as is for now.
However, we can say for sure:
- US State Dept boundary data is not correct
- HDX data (from an unidentified agency in Moçambique) is not correct
- maplibrary data is not correct
It's truly a mess, but I firmly believe we can get it to a satisfactory level until an authoritative source is identified.

To add to the discussion:
changeset/91086581

Okay here's my take - I continued the draft boundary from cRaIgalLAn and took it over to Malawi side.
changeset/91086581
I have more to add as well in the next few days.
So the HDX boundary data is NOT good, especially on Moç/Mal border in corner near Namitete. It goes onto the Malawi side of the arterial road, and it shouldn't. That is a Malawi highway.
