# description
**Spatial predicate** using **OGC CQL2 (JSON semantics)** applied to one or more geometry targets in an item. This is where clients express spatial intent. Key ideas: - `targets`: one or more **JSONPath-like** pointers that locate geometry    fields within each item document (e.g., `$['availableAt'][*]['geo']`). - `op`: spatial operator (CQL2). Common ones:      • `S_WITHIN`     (A is completely inside B)     • `S_INTERSECTS` (A intersects B)     • `S_CONTAINS`   (A contains B)     • `S_DWITHIN`    (A within distance of B) - `geometry`: **GeoJSON** literal used as the predicate reference geometry. - `distanceMeters`: required for `S_DWITHIN` when using a GeoJSON Point/shape. - `quantifier`: if a target resolves to an array, choose whether **ANY** (default),    **ALL**, or **NONE** of elements must satisfy the predicate.  CRS: unless otherwise stated, all coordinates are **EPSG:4326**. 

# properties.targets.description
'One or more JSONPath-like pointers to geometry fields within the item.  Example pointers:  - `$[''availableAt''][*][''geo'']` (array of site Points)  - `$[''itemAttributes''][''ride:dropOff''][''geo'']` (drop zone Polygon)' 

# properties.distanceMeters.description
For `S_DWITHIN`: maximum distance in meters from the target geometry to `geometry` (e.g., "within 5000 m of this Point"). Ignored for other ops.

# properties.quantifier.description
'How to evaluate when `targets` resolves to an array - - **any**: at least one element matches (default) - **all**: every element must match  - **none**: no element may match' 

# properties.srid.description
Coordinate Reference System identifier for `geometry`. Default is `"EPSG:4326"`. If provided, servers MAY reproject to EPSG:4326 internally.
