Class AggregateField
Defines a field or statistical ArcadeExpression for summarizing aggregated data from an AggregationFeatureReduction.
Inheritance
Namespace: Esri.ArcGISRuntime.Reduction
Assembly: Esri.ArcGISRuntime.dll
Syntax
public sealed class AggregateField
Remarks
Feature reduction uses statistical methods to aggregate geoelements into logical groups based on their location. Attribute values for each group (AggregateGeoElement) can be summarized for any numeric field using a specified AggregateStatisticType, such as the average, maximum, or sum. A common workflow is to summarize aggregated groups with the number of geoelements they represent.
