so if you go to https://jmapb.github.io/nycaabs/?search=1089808 it'll load all the building info and in the table below you'll see the first section called "Footprint". There you'll see the date this (version of) building was completed, if it's completed/demolished/under construction, and its height. The newest height is most likely the current one..
You can also click on "View BBL @ ZoLa" to open Zola and there you find how many floors a building it, how many apartments it has (and other unrelated to osm, but still interesting info).

jmapb's site also links to zoning documents. Zoning diagrams type "ZD1" most often have architectural drawing of the building with dimensions and heights of all/most sections of the building. They are very useful if you ever get into detailed 3d mapping of buildings.

You can spot traffic signals from satellite imagery by distinctive diagonal poles/gantry extending from corners of the intersection towards the middle of it. On 12th ave and 66th st you can see them extending from W and E corners of the intersection.
On 12th ave and 45th st they are and their shadows are more clearly visible.

Hello.
Are you sure about this edit? Those areas are pools. It just might be empty/dry now during the winter months..

"DSNY" should probably be expanded or tag renamed to operator:short

If you search for 400 West 113th Street on jmapb's website it'll find BIN 1089808

That's why jmapb's site is so helpful. :) It automatically looks it up in the correct places. And if you don't have BIN, you can search by address or even from the map on the right side.

Read your own wiki link to building=semidetached_house!🤦‍♂️

Apartment building doesn't need to have one main entrance. There are plenty of apartment buildings with either multiple main entrances or with apartment access directly from the street.
Apartment building is a residential building with multiple independent dwellings. The type of access to them doesn't determine that.

Please read up on the ref= tag ref=* and how it's different from the name= tag

Apartment building doesn't have to be a huge multistory block. It can be a smaller 2-3-apartment building too. Based on the address nodes distribution the density looks to be higher like apartments rather than single-family townhouses

Yes, and at least 2 of these buildings have only 2 address nodes on them, meaning it's actually just 2 semi-detached buildings. And other buildings do not look like townhouses.

It doesn't matter where I'm from or if I've been around this address. Just like you mapped it from the satellite imagery, I can map it too and I see that the way you mapped it in this edit is wrong.

Ah, it's bad to waste your time, but ok to waste my time fixing your sloppy mapping? That's rather disrespectful.

Alright, refusing to cooperate and improve on your mapping deficiencies. I'll raise your account to DWG's attention, which can result in temporary or permanent suspension.

Ultimately, it didn't matter what iD shows. We are not mapping for iD or for any other specific mapping style. We are mapping to make sure the data is accurate on its own, not looks pretty in that or this map view.

This is not what I asked you about...

I don't know what "DC" is.
Please provide supporting evidence that this area is named the way you claim it's named.
