Axis-order reversal (lat/lng swap)
Data qualityCoordinates supplied as [lat,lng] where [lng,lat] is expected place geometry in the wrong hemisphere.
Detection
Coordinate out of range but valid when swapped.
Mitigation
- Range-check and swap-detect
- Reject rather than guess when ambiguous
Affected conversions
- PointH3
- PolygonH3 (intersects)
