Is this similar to what vricon[1] does?

I was searching around and found something noting they won a contract to build the Army's One World Terrain 3d model. This OWT appears to be some kind of classification for applying sat imagery over terrain data sets, maybe?

It looks like they're a firm that does large-scale photogrammetry to build 3D models worldwide--this is just a tutorial on how to combine existing topographic datasets (e.g SRTM or a USGS elevation product) with satellite imagery to generate small-scale 3D maps in R. Similar in concept, vastly different in scale and execution

Ok thanks for the explanation! I read through the tutorial and it looks like a fun project to get started in.

One thing also for readers is that https://dwtkns.com/srtm30m requires an account with https://urs.earthdata.nasa.gov to download tiles.

Good to know, thanks! I'll add a note mentioning the need for an account.
