New as part of the June 2021 release of ArcGIS Online is a new Instant App: Countdown! Show a specified number of top or bottom features in your map as sorted by a particular attribute. This enables data journalists, decision support analysts, and others to create an app that delivers an interactive, data-driven tour of features. In addition to the countdown experience itself, an interactive Leaderboard (sorted list) section provides an at-a-glance view of multiple features. Details sections help orient your viewers and tell a complete story by providing context alongside map.
Countdown is the newest template in Instant Apps and is currently in Beta. Like all Instant Apps, you can easily place your web map in an app from within the New Map Viewer.
Easy configuration experience
There are three major section types to choose from: Details, which is a text-based section appropriate for introductions, conclusions, or summaries, as well as Countdown and Leaderboard, both of which pull from your web map’s pop-up.
In this example app, there is a Details section titled Intro, followed by a Countdown section, Leaderboard section, and lastly a Details section titled Conclusion. Adding and reordering these sections is simple in the configuration panel:
In the app itself, the sections appear in the side toolbar. People viewing this app can experience each section and click Next at the bottom to navigate through, or click the sections on the side toolbar for a self-directed experience.
Details sections are text-based sections designed to help you provide context alongside your map. The name you give your details sections, such as Intro and Conclusion, will appear on the side toolbar of the app for your viewers to see. These details sections can be used to tell a narrative story around the trends and geographic differences you are presenting in your app, along with some key takeaways. These sections can also be used is a great place to provide definitions, sources, and more information.
The Countdown section is the bread and butter of this focused Instant App experience. It’s a guided tour of the top (or bottom) features of the map. Sorting is based on the attribute chosen. In this example app, I’ve chosen 10 as the number of features, and I’ve chosen the attribute: Median Age of Total Population. Hence, the app shows the top 10 counties with the highest median age.
The information displayed on the side comes directly from the web map’s pop-up, including any charts, images, or other media.
Accompanying the map-based countdown experience is an optional list-based Leaderboard section. The Pin to Compare button allows the app’s viewers to pin a particular feature to compare with others on the list. The leaderboard section does not need to have the same number of features as the countdown. In this example, the leaderboard has a list of the top 25 oldest counties, whereas the countdown goes through the top 10.
With more features listed, the higher potential for ties in the data to show up. The numeric rankings on the list honor ties in the data. For example, there are two counties in the United States with a median age of 57.4. These two counties are both ranked 13, and the next ranking that displays is 15 (there is no county ranked 14).
Express vs. Full Setup
Upon entering the app configuration in any Instant App, you are taken to Express Setup, a quick way to get started by only configuring the core options. If you want more control over your app, enter Full Setup. Full Setup includes options such as:
- Having the legend show up when the app loads.
- Changing the placement of app widgets through the Position Manager.
- Choosing a Light or Dark theme, or shared theme to take advantage of branding colors set by your ArcGIS Online organization’s administrators.
Interactive viewing experience
Those viewing your app can interact with any feature in the map, not just those highlighted in the Countdown or Leaderboard sections. This allows viewers to view and dock the pop-up for their own feature of interest, such as their own county, school, etc. and compare it to those highlighted in the app. For example, I docked the pop-up for Esri’s home county of San Bernardino so as to compare it with others in the leaderboard:
I’ve used Geo List in the past, what does this mean for me?
If you are familiar with the Geo List app available in Configurable Apps, here’s what this means for you:
- Any existing apps that you’ve created with Geo List will be unchanged.
- Existing Geo List apps can be reconfigured based on the options that app provided. However, in order to take advantage of the new options and section types such as Leaderboard and Details, create a new Instant App with the Countdown template.
- Countdown is only released as Beta right now.
