Instructions provided describe how to convert a point feature class to a polygon feature class.
There are several methods that can be used to accomplish this:
If the points represent polygon boundaries
Use the Points To Line tool with the 'Close Line' option checked to ensure every output line feature's end point matches up with its start point, followed by the Feature To Polygon tool to connect the points to create a polygon.
Note: The Feature To Polygon tool is available only for ArcGIS for Desktop Advanced.
If the points are in a cluster area
Use the Aggregate Points tool to create a polygon representing the cluster area.
Note: The Aggregate Points tool is available only for ArcGIS for Desktop Advanced.
