The Settlement Matrix
"People occupy space; settlements give that population a spatial form."
The Spatial Organization of Humanity
We take the population from Realm 17 and ask: How do humans spatially organize themselves? A settlement has two fundamental geographic dimensions: SITE (what it physically sits on) and SITUATION (where it sits relative to everything else).

Exit Portal
We have tracked the organization of humanity into distinct spatial points—from isolated hamlets to sprawling megacities. We understand their internal morphology and their position in a hierarchy. But these points do not exist in isolation. They are connected by veins and arteries carrying massive flows of materials, capital, information, and people. It is time to examine the circulatory system of the modern world.
