Compute geometric extent based on all input geometries. The options Bounding Box, Convex Hull and Union are possible.

**Category:** Geometric

**Parameter:**

- Extent Type
__Occurrence:__1..1

- Geometries
__Description:__Source geometries (eager)__Occurrence:__1..n

- Extent
__Description:__Computed extent__Occurrence:__1..1

The compute extent function uses the source data geometries to derive the geometric extent and map it to the target geometry.
Three different options are available for extent computation: Bounding Box, Convex Hull and Union. Visual examples are
provided below.

**Bounding Box**

The bounding box option maps the smallest rectangle shape that encloses the source data geometries to the target data geometry.

**Convex Hull**

The convex hull option maps the smallest convex shape that encloses the source data geometries to the target data geometry.
