+</p>
+
+***
+
+## Description
+A single polygon geometry is derived from any geometry (except a
+point itself)
+
+***
+
+## Required inputs
+
+* JTS Geometry
+* EPSG Code
+* Polygon Output Type
+***
+
+## Configuration
+
+### Geometry field
+Input Geometry
+
+### EPSG field
+Integer value representing EPSG code
+
+### Point Output Type
+Chose between 
+* **Bounding Box:**  Gets a Geometry representing the bounding box of this geometry, whose vertices are 
+(minx miny, minx maxy, maxx maxy, maxx miny, minx miny).
+* **Convex Hull**: Computes the smallest convex Polygon that contains all the points in the Geometry.
+
+***
+
+## Output
+A polygon geometry with EPSG code.
+
