Change point colors based on zoom levels in Portal for ArcGIS and ArcGIS Online Map Viewer

Summary

In Portal for ArcGIS and ArcGIS Online, it may be necessary to dynamically change the colors of point features based on different zoom levels. This is to enhance the interpretability of maps such as contextual information to represent the data density of a location.

This article describes the workflow to change point colors based on zoom levels in Portal for ArcGIS and ArcGIS Online Map Viewer.

Procedure

1. Open the map containing the point layer in Portal for ArcGIS or ArcGIS Online Map Viewer.
2. Duplicate the desired point layer. Refer to Portal for ArcGIS: Duplicate a layer or ArcGIS Online: Duplicate a layer for instructions.
3. Click the duplicated point layer to open its Properties pane.
4. Under Visibility, set the Visible range to display when the point layer is zoomed out.

5. Specify the symbology color of the point layer. Refer to Portal for ArcGIS: Apply a style or ArcGIS Online: Apply a style for instructions.
6. Repeat Steps 3 through 5 for the original point layer when the layer is zoomed in.

The point colors are changed when the map is zoomed in or out, as demonstrated in the image below.
