A linear ring is a closed LineString with four or more positions.

The first and last positions are equivalent, and they MUST contain identical values; their representation SHOULD also be identical.

A linear ring is the boundary of a surface or the boundary of a hole in a surface.

A linear ring MUST follow the right-hand rule with respect to the area it bounds, i.e., exterior rings are counterclockwise, and holes are clockwise.

GeoJSon fundamental geometry construct.

A position is an array of numbers. There MUST be two or more elements. The first two elements are longitude and latitude, precisely in that order and using decimal numbers. Altitude or elevation MAY be included as an optional third element.

Implementations SHOULD NOT extend positions beyond three elements because the semantics of extra elements are unspecified and ambiguous. Historically, some implementations have used a fourth element to carry a linear referencing measure (sometimes denoted as "M") or a numerical timestamp, but in most situations a parser will not be able to properly interpret these values. The interpretation and meaning of additional elements is beyond the scope of this specification, and additional elements MAY be ignored by parsers.

A GeoJSON object MAY have a member named "bbox" to include information on the coordinate range for its Geometries, Features, or FeatureCollections. The value of the bbox member MUST be 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.
