Function:

This activity provides a simple way to determine the combined extent of all the features in a FeatureSet.

In a Workflow:

In a workflow, it is very common to perform a query to obtain a FeatureSet. You then want to zoom the map to the extent of all the features. The GetFeatureSetExtent activity loops through all the features in the FeatureSet and calculates the combined extent. This is possible using multiple activities running a loop, but the GetFeatureSetExtent activity simplifies the process.
