On the edge: Atlas (Beta) Instant App
For instructors who routinely use a collection of maps, consider creating an Atlas Instant App to allow easy discovery and interaction for your students. It's a great tool for organizing maps and providing some powerful interactivity including drawing, 3D, "weather" and sunlight models.
I built a quick example of the Atlas Instant App with a few simple maps available under “Open Map”.
To create your own Instant App, login to your ArcGIS Online organization. Use the “waffle” and click “Instant Apps”.
Choose the Atlas app. Set the group to point to your group where you have shared web maps or data layers. These maps and data will be available in your new Instant App under the “open map” or “Add layer” buttons. Supporting documentation is here.
Be sure to share your Atlas Instant App – either to your organization or publicly. Lastly, keep in mind, that as of April 2023, the Atlas Instant App is in beta. Over time, it will continue to improve!
