### `Optional`bbox[](#bbox)

bbox?: [BBox](https://docs.maptiler.com/sdk-js/api-reference/types/Externals.BBox/)

Bounding 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](https://tools.ietf.org/html/rfc7946#section-5)

Inherited from [GeoJsonObject](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.GeoJsonObject/).[bbox](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.GeoJsonObject/#bbox)
