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...

That's what I was expecting as well. Still a cool project nonetheless.

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).

> But other than taking a few photos of holiday mementos and lens-flaring sunsets, what’s the point?

OT, but for me the point is not having my body absolutely panic from experiencing all kinds of rotation and sudden lateral displacement without anything happening visually. Honestly, I have no idea how people fly anywhere else, I wouldn’t be able to. The speeds and forces experienced even on a calm commercial flight are, as far as human evolution goes, total nonsense.

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.

To explain the underwhelmed response I guess most people were expecting ’google maps quality’ 3d models. Which is not an unreasonable expectation, given an aerial platform such as a drone converting photos to 3d models of large areas is commoditized. Just dump photos to an application such as Agisoft Metashape or Luma, wait a bit and you can get something like this for example: https://skfb.ly/6DvVP
