## Description

Checks the geometry event if the geometry is simple and / or empty.

***

## Required inputs

* JTS Geometry
* EPSG Code
* Validation Type
* Validation Output


***

## Configuration

Validates geometry of different validations categories.


### Point Geometry Field
Input Point Geometry

### EPSG field
Integer value representing EPSG code

### Validation Type
* IsEmpty -  Geometry is empty.
* IsSimple - Geometry is simple.  The SFS definition of simplicity follows the general rule that a Geometry is simple if it has no points of self-tangency, self-intersection or other anomalous points.
  * Valid polygon geometries are simple, since their rings must not self-intersect.
  * Linear rings have the same semantics.
  * Linear geometries are simple if they do not self-intersect at points other than boundary points.
  * Zero-dimensional geometries (points) are simple if they have no repeated points.
  * Empty Geometries are always simple!

### Validation Output
Chose the output result of the filter.
* Valid - all valid events are parsed through
* Invalid - all invalid events are parsed through

***

## Output

All events that match the validation output.
