OptionalbboxBounding box of the coordinate range of the object's Geometries, Features, or Feature Collections. The value of the bbox member is an array of length 2*n where n is the number of dimensions represented in the contained geometries, with all axes of the most southwesterly point followed by all axes of the more northeasterly point. The axes order of a bbox follows the axes order of geometries. https://tools.ietf.org/html/rfc7946#section-5
Metadata about the NASR cycle and build.
Specifies the type of GeoJSON object.
A GeoJSON FeatureCollection with top-level metadata properties describing the NASR cycle and build provenance. Each feature's geometry is a Polygon representing one airspace boundary, and its properties contain the airspace type, name, identifier, floor/ceiling, state, controlling facility, and schedule description.
