# Geometry standardize

> Supported in: Batch, Faster, Streaming

Given a valid geometry, standardizes it by enforcing the right-hand rule on the input, which is the convention for GeoJSON. This enables equality comparisons between equivalent geometries. This expression may reverse linestrings.

**Expression categories:** Geospatial

## Declared arguments

* **Expression:** Geometry to be standardized.<br>*Expression\<Geometry>*

**Output type:** *Geometry*

## Examples

### Example 1: Base case

**Argument values:**

* **Expression:** `geometry`
