Latitude in decimal degrees (WGS84).
Longitude in decimal degrees (WGS84).
OptionaltoleranceOptional tolerance in degrees for the centroid match. A feature is
returned when both |centroidLon - lon| and |centroidLat - lat|
fall below this value. Defaults to 0.0001 (~11 m), generous enough to
absorb floating-point round-trips through URL parsing for centroids
encoded to ~5 decimal places.
A query describing a geographic position and tolerance for a centroid-based airspace lookup.
