## Signatures

```sql theme={"system"}
ST_ExtentBasedSubDivideExplode(geom: Geometry, maxWidth: Double, maxHeight: Double)
```

```sql theme={"system"}
ST_ExtentBasedSubDivideExplode(geom: Geometry, maxWidth: Double, maxHeight: Double, algorithms: String)
```

```sql theme={"system"}
ST_ExtentBasedSubDivideExplode(geom: Geometry, maxWidth: Double, maxHeight: Double, maxVertices: Integer, maxDepths, algorithms: String)
```

## Parameters

<ParamField body="geom" type="Geometry" required>
  The input geometry.
</ParamField>

<ParamField body="maxWidth" type="Double" required>
  The max width value.
</ParamField>

<ParamField body="maxHeight" type="Double" required>
  The max height value.
</ParamField>

<ParamField body="maxVertices" type="Integer">
  The maximum number of vertices.
</ParamField>

<ParamField body="maxDepths" type="Integer">
  The maximum recursion depth for subdivision.
</ParamField>

<ParamField body="algorithms" type="String">
  The algorithms value.
</ParamField>

## Example

```sql theme={"system"}
SELECT ST_ExtentBasedSubDivideExplode(ST_GeomFromText("LINESTRING(0 0, 85 85, 100 100, 120 120, 21 21, 10 10, 5 5)"), 30, 30)
```
