# Filter by geometry type

> Supported in: Batch, Faster, Streaming

Nulls any values in the geometry column that are not of the provided geometry types.

**Expression categories:** Geospatial

## Declared arguments

* **Expression:** The geometry column to filter.<br>*Expression\<Geometry>*
* **Geometry types:** The set of geometry types to keep.<br>*Set\<Enum\<Feature, FeatureCollection, GeometryCollection, LineString, MultiLineString, MultiPoint, MultiPolygon, Point, Polygon>>*

**Output type:** *Geometry*

## Examples
