Part 2. Sample Use Case

In the second part of this book you’ll build a field collection application for mobile devices. By the end of part 2 you’ll learn how to structure your application so that it can grow as needed, build a mobile-friendly data-collection application, and even learn advanced techniques for disconnected editing:

• In chapter 4, you’ll set up an ArcGIS Developers account and learn how to use Dojo to build your application.
• In chapter 5, you’ll learn how to edit features on the map and use authentication to secure your application, as well as how you can use Local-Storage to enable disconnected editing.
• In chapter 6, you’ll focus on building an application for use on a desktop browser, freeing you from some limitations of a mobile environment. You’ll also learn how to use OAuth 2.0 with ArcGIS Online and store your credentials to allow users to log in and out. This chapter also covers how you can integrate data collected in the field with some non-spatial data, such as data from a separate web service.
• In chapter 7, you’ll be introduced to more advanced subjects and techniques. You’ll learn about the ArcGIS WebMap specification and how to use it to configure your map. You’ll also learn how to build your entire application from a single JSON file that will configure your widgets for you. This chapter will also describe an alternative to disconnected editing using a library called PouchDB.
