Can the heat map symbology be applied to polygons in ArcGIS Pro?

Last Published: May 16, 2023

Answer

No, the heat map symbology only applies to point features. It displays the relative density of points as a dynamic raster visualization with a range of colors. In ArcGIS Pro, the only way to apply the heat map symbology is to create a point from the polygon feature classes.

  1. In ArcGIS Pro, navigate to the Contents pane and right-click the polygon layer.
  2. Click Attribute Table and add new fields to the polygon feature class. Refer to ArcGIS Pro: Create a field and apply a domain and default value for instructions.
  3. Use the Calculate Geometry Attributes tool to populate the new fields with the X and Y coordinates of each polygon. Refer to How To: Calculate geometry in ArcGIS Pro for instructions.
Note:
In Step 2 of How To: Calculate geometry in ArcGIS Pro, select the new fields for the Target Field parameter and the preferred property from the drop-down list in the Property parameter.
  1. Add the X and Y coordinate data as a point layer using the XY Table to Point geoprocessing tool. Refer to ArcGIS Pro: Add x,y coordinate data to a map or scene for instructions.
Note:
Alternatively, it is possible to create the point feature class from the centroids or extents of the polygons. Refer to How To: Add point features to the centroid and the minimum and maximum extent of a polygon feature in ArcGIS Pro for more information.
  1. Draw the point feature layer with heat map symbology to display the relative density of the points. Refer to ArcGIS Pro: Draw a layer with heat map symbology for instructions.
