Scope: relation
Default severity: error
Certainty: deterministic
Compares two dataset extents in a common CRS. A failure means their transformed bounding boxes do not overlap.
PASS: transformed extents overlap.
FAIL: transformed extents do not overlap.
UNKNOWN: comparable bounds cannot be established.
NOT_APPLICABLE: the context does not contain exactly two subjects.
Bounding-box overlap is not treated as proof that geometries intersect.
