Symbolizing Multi-Part Features with Convex Hulls in ArcGIS Pro

PaolaBonato — Tue, 04 Mar 2025 08:16:09 GMT

The goal is to display a feature as multipart, polygon, or point depending on the scale. I am using ArcGIS Pro 3.3, and I would like to dynamically adjust the features's representaion based on the scale. Specifically:

Below 1:5,000 - Display as a multipart polygon

Between 1:5,000 and 1:20,000 - Display as a polygon (using the convex hull of the multipart polygon)

Above 1:20,000 - Display as a point of the centre of the multipart polygon

I was able to visualize the point from the multipart polygon using the Scale tool in Symbology following the instructions provided here. However, I couldn't visualize the convex hull polygon from the multipart feature. Is there any solution or do you have any suggestion?

This is a sample image illustrating the idea.
