Create the mean center of a group of point features within a polygon in ArcGIS Pro

Summary

In ArcGIS Pro, a map displaying numerous point features provides detailed information about a region. However, a lot of point features may add extra noise to the map, making it difficult to observe trends. The map can be visually improved by displaying only the mean center of a group of point features within the polygon.

This article provides the workflow to create the mean center of a group of point features within a polygon using the Pairwise Intersect tool and the Mean Center tools available in ArcGIS Pro.

Procedure

1. Open the ArcGIS Pro project.
2. In the Geoprocessing pane, search for and click Pairwise Intersect (Analysis Tools).
3. Configure the parameters in the Pairwise Intersect pane.
   1. For Input Features, select the point and polygon feature layers from the drop-down list. In this example, SanFran_customers and Group_region are selected.
   2. Leave the other parameters as default and click Run.

4. ​​​​​In the Geoprocessing pane, search for and select Mean Center (Spatial Statistics Tools).
5. Configure the parameters in the Mean Center pane.
   1. For Input Feature Class, select the feature layer created in Step 3. In this example, SanFran_custom_PairwiseInter is selected.
   2. For Case Field, select the polygon ID field to group the point features by the polygon ID. In this example, the field is 'ID'.
   3. Leave the other parameters as default and click Run.

The map below shows the mean centers of the groups of point features within the polygons symbolized as red dots.
