# Geometry contains

> Supported in: Batch, Faster, Streaming

Determines if geometry a contains geometry b. Points or lines lying on the boundary of a polygon are not contained within another geometry.

**Expression categories:** Geospatial

## Declared arguments

* **Geometry a:** Geometry a.<br>*Expression\<Geometry>*
* **Geometry b:** Geometry b.<br>*Expression\<Geometry>*

**Output type:** *Boolean*

## Examples

### Example 1: Base case

**Argument values:**

* **Geometry a:** `geometry_a`
* **Geometry b:** `geometry_b`
