This is not photogrammetry as the word is usually understood these days.

Photogrammetry usually means constructing a 3D model out of a number of 2D photos from lots of different angles, although there are broader definitions as well [1].

This is just skewing a photo you took out the window to overlay it on a map.

From the title, I was expecting this to be something about constant super-hi-res photography attached to commercial flights that would actually let you build 3D models of the landscape...

I think that's probably a function of the context you're encountering photogrammetry in, it's literal meaning (as described in the Wikipedia article) is "measuring stuff from photos." I believe what you're describing is generally referred to as "3D reconstruction."

For what it's worth, this article was pretty much exactly what I anticipated it to be. But language is funky, and obviously other people shared your expectation (which makes it a good comment in my view).

Even in 3D rendering for animation, video games, archviz, etc. I often hear photogrammetry discussed in the context of making reusable textures, not just making specific 3D models.
Correct, the technique is called orthorectification.
That's what I was expecting as well. Still a cool project nonetheless.
