Smooth Polygon Tool, Generalization Toolset, Cartography ArcToolbox
summary
Smooths sharp angles in polygon outlines to improve aesthetic or cartographic quality.
Usage
There are two smoothing methods available:

The Polynomial Approximation with Exponential Kernel (PAEK) method (PAEK in Python) smooths polygons based on a smoothing tolerance. Each smoothed polygon may have more vertices than its source polygon. The Smoothing Tolerance parameter controls the length of a moving path used in calculating the new vertices. The shorter the length, the more detail that will be preserved and the longer the processing time.
The Bezier interpolation method (BEZIER_INTERPOLATION in Python) smooths polygons without using a tolerance by creating approximated Bezier curves to match the input polygons.
Use the Input barrier layers parameter to identify features that must not be crossed by smoothed polygons. Barrier features can be points, lines, or polygons.

Processing large datasets may exceed memory limitations. In such cases, consider processing input data by partition by identifying a relevant polygon feature class in the Cartographic Partitions environment setting. Portions of the data, defined by partition boundaries, will be processed sequentially. The resulting feature class will be seamless and consistent on partition edges. See Generalizing large datasets using partitions for more information.

Caution:
The Cartographic Partitions environment setting is ignored when the Handling Topological Errors parameter is set to Do not check for top errors (error_option = "NO_CHECK" in Python) or Flag topological errors (error_option = "FLAG_ERRORS" in Python).

The output polygon feature class is topologically correct. Any topological errors in the input data are flagged in the output polygon feature class. The output feature class includes two additional fields, InPoly_FID and SmoPgnFlag, that contain the input feature IDs and topological errors of the input, respectively. A SmoPgnFlag value of 1 indicates that a topological error is present; a value of 0 (zero) indicates that no errors are present.

Legacy:
Prior to the ArcMap 10.6.1 version of this tool, the Preserve endpoint for rings (endpoint_option in Python) parameter was used to specify whether the endpoint of a resulting isolated polygon ring would be preserved. This parameter is still included in the tool's syntax for compatibility in scripts and models but is now ignored and hidden on the tool's dialog box.
