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.
