If every item contains a bounding-box of the same dimension, then the output has a bounding-box of the GeoJSON supports the following geometry types: Point, LineString, Polygon, MultiPoint, MultiLineString, and MultiPolygon. Geometric objects with additional properties are Feature 3 I have a GeoJSON which is a list of Polygon and MultiPolygon features, one at each line. Indexing into the collection will parse the feature.
