Scope: dataset
Default severity: error
Certainty: deterministic
Checks declared geographic data for implausible angular coordinate ranges. Latitude must remain within ±90 degrees; longitude is allowed within the commonly encountered -360 to 360 degree domain.
PASS: geographic bounds are within supported angular ranges.
FAIL: observed bounds exceed those ranges.
UNKNOWN: finite bounds cannot be established.
NOT_APPLICABLE: the CRS is not geographic.
This rule diagnoses a mismatch between declared CRS semantics and coordinates; it does not identify the correct CRS.
