GeoJSON is a format for encoding a variety of geographic data structures using JavaScript Object Notation (JSON) []. A GeoJSON object may represent a region of space (a Geometry), a spatially bounded entity (a Feature), or a list of Features (a FeatureCollection). GeoJSON supports the following geometry types: Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, and GeometryCollection. Features in GeoJSON contain a Geometry object and additional properties, and a FeatureCollection contains a list of Features.
GeoJSON是一种使用 JavaScript Object Notation（JSON）[RFC7159] 对各种地理数据结构进行编码的格式。GeoJSON对象可以表示空间区域（Geometry）、空间边界实体（Feature）或特征列表（FeatureCollection）。GeoJSON支持以下几何类型：Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon 和 GeometryCollection。 Feature 包含一个 Geometry 对象和其他属性，FeatureCollection 是 Feature 列表。
