Is the part of the road covered by the roof underground? If not, it should not be layer=-1, but the roof should rather be layer=1

What was the purpose of removing layer=1 from building=roof? It's the expected tag pairing.

May I ask you to revert moving traffic_calming=island from relations to kerbs?

fixed
changeset/167506197

Reverted: the address was mapped from the ground

reverted: the fences are still there, construction works haven't finished, and the demolished house should be kept both for those mappers who only map from the outdated satellite and as an address tag

node/12846406881 duplicates node/12844284426 ?

reverted - the shop is still signed as Mplus, and the website also has that name

changeset/166143330

rv - the segment contains turn lanes, should be fixed differently

changeset/166143149

reverted - I've checked, there's a gap

changeset/166125323

It's 2.5 GEL for citizens of Georgia, and 12 GEL for foreign citizens. But I don't know how to tag that...

სკვერი = сквер ~ park =/= square = მოედანი
То есть то под идее должно быть названием какого-то парка, с en = Erekle Kuloshvili Park

Whoops! Thanks for fixing!

Well, there is a Frankensteinish ubani called "ვეძისი, ყაზბეგი, გოთუა, საბურთალო", which has it's own local government office:

Doesn't that mean that there is an area referred to as ყაზბეგი?

Why opposite? The arrows point in the same direction: https://imgur.com/lSkukbQ
But really, one-way direction for footways is completely unpractical to map, even when there is some signage that prescribes it. People tend to ignore it completely, and would expect routing software to direct them in the shortest direction, not in the opposite way. Of course, for narrow passages and/or difficult waymarked trails one way tags are indeed useful; but in our case in practice it's oneway=no.

deleted node/12796252784: the mtb track is virtual here (in the air, cycleway=gap_jump)

changeset/165583977

reverted: I've checked, both paths are there, as well as the picnic site:

reverted - it is drinkable, I've checked. No smell, no taste, nothing suspicious. Moreover, when there was no water in Tbilisi last summer, all the neighbourhood was collecting water from this tap

rv for way(id:281583468): no. 19 is the adjacent building

changeset/165170305

Ooops! I've misidentified the photo that I had taken, it was actually of თეთრი კვადრატი ჯიქიაზე nearby.
The present building is still invisible from over the fence. I've simplified its geometry and removed levels number for now: changeset/164845232
Thanks for sticking to the issue!
