# Interface GeoJsonObject

The base GeoJSON object. [https://tools.ietf.org/html/rfc7946#section-3](https://tools.ietf.org/html/rfc7946#section-3) The GeoJSON specification also allows foreign members ([https://tools.ietf.org/html/rfc7946#section-6.1](https://tools.ietf.org/html/rfc7946#section-6.1)) Developers should use "&" type in TypeScript or extend the interface to add these foreign members.

interface GeoJsonObject {  
    [bbox](#bbox)?: [BBox](https://docs.maptiler.com/sdk-js/api-reference/types/Externals.BBox/);  
    [type](#type):  
        | "Point"  
        | "Feature"  
        | "FeatureCollection"  
        | "MultiPoint"  
        | "LineString"  
        | "MultiLineString"  
        | "Polygon"  
        | "MultiPolygon"  
        | "GeometryCollection";  
}

## Properties[](#properties-1)

### `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)

### type[](#type)

type:  
    | "Point"  
    | "Feature"  
    | "FeatureCollection"  
    | "MultiPoint"  
    | "LineString"  
    | "MultiLineString"  
    | "Polygon"  
    | "MultiPolygon"  
    | "GeometryCollection"

Specifies the type of GeoJSON object.
