I also would like to remove very small contours (like points or small circles) and irregular lines. I am struggling with the Smooth Line/Smooth Polygon &amp; Simplify Line tool parameters.

Take a look and see if this helps:</P><P><A href="https://support.esri.com/en/technical-article/000027916" target="_blank">https://support.esri.com/en/technical-article/000027916</A></P><P>&nbsp;</P> Tue, 07 Feb 2023 20:41:39 GMT https://community.esri.com/t5/arcmap-questions/i-m-struggling-to-smooth-contours-in-arcmap/m-p/1255889#M4295 AdrianWelsh 2023-02-07T20:41:39Z
