      Chapter 2

      Hosted feature layers and Esri Story Maps

      Apps are important because they are the face of Web GIS: They bring Web GIS to life. You created a web app in chapter 1. The ArcGIS Web GIS platform offers far more web apps. This chapter presents an overview of ArcGIS configurable apps, which include apps from ArcGIS Online, Portal for ArcGIS, Esri Story Maps, and ArcGIS Solutions. The chapter then introduces the basic components in today’s Web GIS apps and the foundation supporting these components, which is web services technology. You’ll learn about feature services and feature layers, which are the most common types of operational layers. The chapter then teaches how to create a hosted feature layer, design layer styles using smart mapping, and configure layer pop-ups with ArcGIS Arcade. The tutorial section further illustrates how to use layers from the Living Atlas of the World, and how to create a web app using Story Map Journal .

      Learning objectives

       Understand the suite of ArcGIS configurable apps.

       Understand the suite of Story Maps templates.

       Grasp the concept of web services.

       Create hosted feature layers using geocoding.

       Design layer style using smart mapping.

       Configure pop-ups with multimedia and Arcade.

       Explore Living Atlas of the World contents.

       Create an app using Story Map Journal.

      ArcGIS offers many ways to build web apps. The green lines in the figure highlight the technology presented in this chapter.

      Apps, the face of Web GIS

      GIS apps are lightweight map-centric computer programs that end users use on mobile devices, in web browsers, or on desktops. Web GIS end users directly interact with apps. The back-end data, services, and server computation power of Web GIS become live and useful through GIS apps. ArcGIS provides ready-to-use web apps, including configurable apps, mobile apps, app builders, and more. Mobile apps and app builders such as Web AppBuilder for ArcGIS will be introduced in other chapters. This chapter focuses on configurable apps.

      ArcGIS configurable apps enable the broad user community to build engaging apps with no GIS or web development skills. ArcGIS platform provides the following configurable apps:

       ArcGIS Online and Portal for ArcGIS app templates: These apps are also called configurable apps.

       Esri Story Maps: Some of the Story Maps apps have become ArcGIS Online and Portal for ArcGIS app templates.

       ArcGIS Solutions apps: These apps provide data and map and app templates for you to quickly jumpstart your applications projects.

      Using ArcGIS configurable apps generally takes the following three steps: choose, configure, and deploy.

      Using ArcGIS configurable apps generally takes three steps: choose, configure, and deploy the app.

       Choose: In this step, you discover the data, maps, and configurable apps that match your app requirements. Consider the following factors:Purpose: Who is your intended audience? Where and how will your audience use your app? What key points do you want to communicate?Functional requirements: What critical functionalities support your purpose?Aesthetic: How will the app’s layout and color scheme support your brand or message?

       Configure: Configure the apps to use your data, and brand the apps for your organization.ArcGIS Online and Portal for ArcGIS apps templates typically have a configuration user interface.Esri Story Maps provide a builder user experience.Solutions apps provide a configuration file that often requires manual editing.

       Deploy: Deploy your new apps for your end users.Esri automatically hosts apps created using ArcGIS Online and Portal for ArcGIS app templates and Story Maps in the cloud. If needed, you can download the source code for these open-source apps and host the apps on your own web servers.Solutions templates need to be deployed to and hosted on your own web servers.

      ArcGIS Online and Portal for ArcGIS app templates

      ArcGIS Online and Portal for ArcGIS provide many app templates. To help you choose the right one, ArcGIS organizes these apps based on their purposes in the following categories:

       Build a story map: These apps are adopted from Esri Story Maps.

       Collect and edit data: These apps primarily collect data. These apps fall into the subcategories of crowdsourcing and general editing.

       Compare maps and layers: These apps are focused on comparing geographic phenomena.

       Display a scene (3D): These apps allow you to interact with 3D scenes outside of scene viewer.

       Explore and summarize data: These apps allow your users to interact with attributes and in some cases other services to facilitate a deeper exploration of the content in your web map.

       Make a gallery: These apps create a gallery of maps, apps, or other content that can be used as a convenient access point for all your geographic content. These apps require a group.

       Map social media: These apps include social media content to supplement your message with relevant content.

       Provide local information: These apps highlight the resources available at a location. Options include highlighting all features within a certain distance of a location and communicating that a user’s address is located within a certain geographic area.

       Route and get directions: Use these apps to provide driving directions from a user-defined starting point to the geographic features within your map.

       Showcase a map: These apps include many options for presenting thematic or general maps. The apps include legends, descriptions, and other basic tools to assist users in understanding the message of the map.

      Esri Story Maps

      Every story happens somewhere. Web GIS can enhance storytelling by visually and intuitively illustrating the “where” component of every story. Esri Story Maps (https://storymaps.arcgis.com) are simple web apps that combine interactive maps, multimedia content—text, photos, video, audio, and intuitive user experiences—to tell stories about the world. Story maps use geography to organize and present information.

      Esri Story Maps combine interactive maps, multimedia content, and user experiences to tell stories.

Main types of configurable app templates provided by Esri Story Maps
Presenting sequential, place-enabled photos or videos
Story Map TourPresents a set of photos or videos along with captions, linked to an interactive map
Presenting a rich multimedia narrative
Story Map JournalCreates an in-depth narrative organized into sections presented
