Split a multi polygon

MarcusAdamski — Thu, 20 Mar 2025 13:17:51 GMT

Hello,

I have several polygons saved as one geomerty and would like to split them into separate polygons. For instance, I would like to split the below into two entities. I've tried Split and Clip functions, but I've been unsucessful. I think Split will only work if geometeries intersect, but this will not happen in this case, as I'm trying to split between the polygons. Any guidance would be very appreciated.
Using ArcGIS Pro 3.3, standard.

Thanks
Marc

Have you tried this tool: Multipart To Singlepart (Data Management)—ArcGIS Pro | Documentation.

I think you're trying to take a single multi-part polygon and create separate single-part polygons.

You can use a geoprocessing tool to do this https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/multipart-to-singlepart.htm

You can also do this interactively from the editing tab in ArcPro. Use the Explode tool in the Divide group of the Modify Features pane. https://pro.arcgis.com/en/pro-app/latest/help/editing/explode-a-multipart-feature.htm
