Divide polygon features based on selected attributes in point features in ArcGIS Pro

Summary

In ArcGIS Pro, a polygon can be divided using the values of point feature attributes, and points with the same attributes can be grouped together within the polygon. For instance, when studying the different types of antenna towers in a town. Polygons can be created to represent boundaries based on the types of antenna towers and similar towers can be combined into a single polygon.

This article describes the workflow to divide polygon features based on selected attributes in point features in ArcGIS Pro.

Procedure

1. Create polygon features around the points using the Create Thiessen Polygon (Analysis) tool.

Note: 
The Create Thiessen Polygon (Analysis) tool is only available with an Advanced license.

1. In ArcGIS Pro, on the Analysis tab, click Tools to open the Geoprocessing pane.
2. Navigate to Toolboxes > Analysis Tools > Proximity > Create Thiessen Polygons.
3. For Input Features, select the point feature from which the Thiessen polygons are generated, from the drop-down list. For this example, it is 'Antenna_Tower'.
4. For Output Feature Class, specify the name, and save location for the Thiessen polygon.
5. For Output Fields, select All fields from the drop-down list.
6. Click Run.

2. Dissolve the Thiessen polygon based on the point feature attributes.
   1. On the Analysis tab, click Tools to open the Geoprocessing pane.
   2. Navigate to Toolboxes > Data Management Tools > Generalization > Dissolve.
   3. For Input Features, select the Thiessen polygon layer created in Step 1 from the drop-down list.
   4. Specify a name for Output Feature Class.
   5. For Dissolve Fields, check or select the desired field(s) to dissolve the lines in the polygon feature.
   6. Click Run.

3. Clip the polygon feature onto the Thiessen polygon.
   1. On the Analysis tab, click Tools to open the Geoprocessing pane.
   2. Navigate to Toolboxes > Analysis Tools > Extract > Clip.
   3. For Input Features or Dataset, select the dissolved Thiessen polygon from the drop-down list.
   4. For Clip Features, select the polygon feature to be clipped from the drop-down list.
   5. Specify a name for Output Features or Dataset.
   6. Click Run.

The polygon feature is divided based on the point feature values as shown in the image below.
