Introduction to Latitude, Longitude & Projections | Physical Geography with Prof. Jeremy Patrich

Welcome back, fellow geographers! In this engaging and informative lecture, we’ll delve into the fascinating world of mapping. We’ll start with the basics of latitude and longitude—think of them as Earth’s own personal address system! You’ll learn how to read these coordinates and what the difference is between the super-precise Degrees, Minutes, and Seconds (DMS) and the simpler decimal degrees. (We’ll also give a quick shout-out to Eratosthenes, the ancient Greek genius who started it all!)

Then, we’ll talk about the magic and the madness of map projections. What happens when you try to flatten a ball? Spoiler alert: things get weird! We’ll show you how maps get made and why they can sometimes lie to you (in a good way!).

Whether you’re a geography student, a trivia buff, or just curious about the world, this video will give you a whole new appreciation for the maps you see every day.

Get ready to see the world from a new perspective!
