I like thinking about map projections, though I am far from an expert in them. As I grew in cartographic experience, I began to learn the ways in which many of them are actually connected to each other. For example, some projections are mathematical blendings of others, while others are simply specific cases of parent projections.

I did a deep dive on the subject, and I compiled what I learned into a poster. It’s free to download, and I’d be happy to hear if anyone ends up using it in a classroom or workplace.
