Feature

  • A GeoJSON feature object is defined by having "Feature" as its "type", a geometry field, and a properties field.

  • The GeoJSON feature object's geometry and properties are represented using the Value format, containing either a Struct or a NullValue.

  • The "type" field of a GeoJSON feature object is always the string "Feature".

A GeoJSON feature object (see RFC 7946) containing the string "Feature" in a field named "type", the geometry in a field named "geometry", and key/value properties in a field named "properties".
