I've converted the raster to a polygon and tried Dissolve, but am still left with a complex shape with holes inside etc. (polygon).</P><P>Can anyone suggest a smoothing function or similar that will outpur a more simple feature?</P><P>Thanks.</P> Tue, 08 Oct 2024 15:57:51 GMT https://community.esri.com/t5/arcgis-pro-questions/simplifying-the-outline-of-a-complex-feature/m-p/1546607#M88990 RichardMorris 2024-10-08T15:57:51Z https://community.esri.com/t5/arcgis-pro-questions/simplifying-the-outline-of-a-complex-feature/m-p/1546704#M88994 <P>You could clean up the raster with raster tools a bit before converting to polygon.</P> <P>For example, see the linked section of a tutorial here:</P> <P><A href="https://learn.arcgis.com/en/projects/classify-land-cover-to-measure-shrinking-lakes/#clean-up-the-classification" target="_blank">https://learn.arcgis.com/en/projects/classify-land-cover-to-measure-shrinking-lakes/#clean-up-the-classification</A></P> <P>See also this help topic:</P> <P><A href="https://pro.arcgis.com/en/pro-app/latest/tool-reference/spatial-analyst/smoothing-zone-edges-with-boundary-clean-and-majority-filter.htm" target="_blank">https://pro.arcgis.com/en/pro-app/latest/tool-reference/spatial-analyst/smoothing-zone-edges-with-boundary-clean-and-majority-filter.htm</A></P> Tue, 08 Oct 2024 19:17:17 GMT https://community.esri.com/t5/arcgis-pro-questions/simplifying-the-outline-of-a-complex-feature/m-p/1546704#M88994 BobBooth1 2024-10-08T19:17:17Z https://community.esri.com/t5/arcgis-pro-questions/simplifying-the-outline-of-a-complex-feature/m-p/1548309#M89133 <P>Thanks&nbsp;<a href="https://community.esri.com/t5/user/viewprofilepage/user-id/95621">@BobBooth1</a>&nbsp; - these are very useful tools for what I'm working on.&nbsp;</P> Sun, 13 Oct 2024 15:54:04 GMT https://community.esri.com/t5/arcgis-pro-questions/simplifying-the-outline-of-a-complex-feature/m-p/1548309#M89133 RichardMorris 2024-10-13T15:54:04Z
