Description
A feature class with fewer than 30 aggregation polygons was provided. This tool requires a minimum of 30 features after aggregation. For incident data when a Polygons For Aggregating Incidents Into Counts parameter value is provided, the aggregation process counts the number of features in each polygon and analyzes the polygons with their associated counts.
Solution
This tool will work with a selection set. If the Polygons For Aggregating Incidents Into Counts feature layer has at least 30 valid polygon features, check to see if there is an active selection set limiting the number of polygons used in the analysis; otherwise, provide a different feature layer for the Polygons For Aggregating Incidents Into Counts value or use a different Incident Aggregation Method option. Alternatively, select an attribute from the Input Features parameter to serve as the Analysis Field value. This makes aggregation unnecessary.
