MapTheOdd / Sources and data register

Public evidence register

See what the atlas is built from.

Every useful claim should lead back to a named source. This register explains what each dataset contributes, the rights checks applied, and where MapTheOdd adds calculated context rather than source fact.

Quick answer: source facts, observations, calculations and reports are kept visibly distinct. Unknown reuse rights fail closed.
