The spatial science — how things are arranged on, and shaped by, the surface of the Earth. The discipline that bridges the natural and the social: its physical half (geomorphology, climate, biogeography) reaches into the Sciences/ libraries, its human half (population, economy, politics, the city) into the rest of Society/, and its methods (cartography, GIS, spatial analysis) into Compute/ and Math/.
Status: Tier 1 complete — 7 notes (the two halves + three human subfields + technique + discipline), authored 2026-06-03.
