# description
**GeoJSON geometry** per RFC 7946. Coordinates are in **EPSG:4326 (WGS-84)** and MUST follow **[longitude, latitude, (altitude?)]** order. Supported types: - Point, LineString, Polygon - MultiPoint, MultiLineString, MultiPolygon - GeometryCollection (uses `geometries` instead of `coordinates`) Notes: - For rectangles, use a Polygon with a single linear ring where the first  and last positions are identical. - Circles are **not native** to GeoJSON. For circular searches, use  `SpatialConstraint` with `op: s_dwithin` and a Point + `distanceMeters`,  or approximate the circle as a Polygon. - Optional `bbox` is `[west, south, east, north]` in degrees.

# properties.bbox.description
Optional bounding box `[west, south, east, north]` in degrees.

# properties.coordinates.description
Coordinates per RFC 7946 for all types **except** GeometryCollection. Order is **[lon, lat, (alt)]**. For Polygons, this is an array of linear rings; each ring is an array of positions.

# properties.geometries.description
Member geometries when `type` is **GeometryCollection**.
