Set Map Extent is usually used after an activity that acquires a new map extent, perhaps through a query or through a union of geometries. The map extent is then sent to the Set Map Extent activity, which sets the map to the given extent. For example, you may use Set Map Extent to zoom to the envelope enclosing a feature.
