Explore the Evidence LayerTerraEvidence keeps formulas, units, sources, dates, uncertainty, and local context attached to the result. Human-readable pages are also structured so search engines and responsible AI systems can understand what each record supports—and what it does not.
Units, methods, assumptions, dates, and local source fields travel with the result.
Missing information and conflicting evidence are labeled instead of silently guessed.
