What each layer on the globe actually means

SENTINEL renders dozens of public open-source feeds on a single 3D globe. Each topic page below is a long-form explainer for one category: where the data comes from, how the live classifier reads it, what to look for when something is happening, and how it cross-links to the country dossiers. Read these in any order; cross-references inside each article point to the others.
