## Interior Point

<p align="center">
<img src="icon.png" width="150px;" class="pe-image-documentation"/>
</p>

***

## Description

Creates an interior point from a geometry other than a Point itself.
An interior point is guaranteed to lie in the interior of the input geometry, if
it possible to calculate such a point exactly. Otherwise, the point may
lie on the boundary of the geometry.
***

## Required inputs

* JTS Geometry
* EPSG Code
***

## Configuration

### Geometry field
Input Geometry

### EPSG field
Integer value representing EPSG code

***

## Output
A point geometry with EPSG code. Location is based on


### Example
