Tip:
This page is for the classic Esri Story Maps templates. If you are looking for the newer story authoring experience, the ArcGIS StoryMaps app is available in ArcGIS Enterprise as of 10.8.1.
Use the Story Map Swipe and Spyglass app template to create an app that allows users to compare layers in one web map, or compare two different web maps, using a vertical swipe bar or spyglass lens. This app is ideal for showing before and after imagery or comparing thematic data. This app template includes an interactive builder to help you create your story map.
For more information, see Story Map Swipe and Spyglass on the Story Maps website.
Requirements
If you use one web map in the application, the web map must contain at least two layers (including the basemap).
If you use two web maps in the application, each web map can contain any number of layers.
