How To: Convert a point feature class to a polygon feature class

Summary

Instructions provided describe how to convert a point feature class to a polygon feature class.

Procedure

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.

1. In ArcMap, click the Geoprocessing tab or open the ArcToolbox window, and navigate to Data Management Tools > Features.
