South America in a Globular Perspective
This post isn't much of a how-to guide or step-by-step instruction but rather a brief rundown of some of the methods, tips, and/or tricks that I found handy when approximating this map of South America inspired by the works of Richard Edes Harrison.
The image below is kind of the brochure that points out where I used some interesting or noteworthy techniques and below are some of the sources. You can download the map here and the 'brochure layout' here.
