FeatureSet object

Overview

This topic discusses the JSON representation of feature sets. The featureSet object contains feature objects, including the values for the fields requested by the user. For layers, if you request geometry information, the geometry of each feature is also returned in the featureSet. For tables, the featureSet does not include geometries.
