Precision in the source

Not every border deserves the same confidence

Precision is inherited from the dataset when available. It describes how the line was encoded, not the overall certainty of every historical claim inside the polygon.

Determined by international law: 205

These precision categories cover all mapped geometries. Label coverage is reported separately above, so the two sets of counts should not be added together.
