As for math, that was the easiest choice as of yet. No doubt, GLM is a "gold standard" at this point. For OpenGL it is, at least. But, like with a lot of the other APIs, I decided to build a wrapper around it rather than directly reference the library in the engine's code. And for physics, well, I had not come upon that answer just yet. I did try to make my own physics logic at some point. And while it was, surprisingly, successful, I wanted more than just a simple physics layer. I wanted something more complex and, more importantly, faster than my implementation. I have not decided upon a physics library yet. But I'll cross that bridge when I come to it.

gdal
GDAL is an open source MIT licensed translator library for raster and vector geospatial data formats.

Don't get me wrong, it's a fantastic and ancient coral reef of a library and tool set but has a lot of inconsistencies in naming conventions and usage (gdal_translate, gdalfinfo). Many geospatial professionals are not savvy enough to leverage it without it being wrapped by someone else like Esri. Windows power users typically install it with something like OSGeo4W [2], whose name I can never remember. Whenever I need it I spin up a Docker image for convenience.
