Chapter 3 focuses on ArcGIS experience builder which allows a person to create experiences on the web using a flexible layout, content, and widgets that interact with different kinds of data (both 2D and 3D). Widgets come in two types: Basic Widgets and Layout Widgets. Basic widgets function as app tools, while Layout widgets are containers that help organize other widgets on a person’s pages or windows. Widgets are also able to talk with each other using message actions or data actions. Message actions perform automatically when given a trigger, while data actions need the user to tell it what to do. Message actions are made up of the triggers, the targets, and the actions which can all work together to create dynamic content.
Chapter 4 is all about mobile GIS which is GIS on mobile devices. Mobile GIS has some advantages such as a large volume of users, mobility, versatile means of communication, ease of data collection, location awareness, and near real time information. There are also some disadvantages that come with the use of mobile devices such as limited memory, limited CPU speed, bandwidth and network connection, screen size, keyboard size, and battery power of the mobile device. There are different types of ways a person can develop apps on a mobile device including the browser based approach, native based approach, or the hybrid based approach. Browser based is less costly and generally more accessible, but does not always perform well, while native based is more expensive, requires more knowledge of mobile software, but generally performs much better. Hybrid based is a mix of both browser and native. This chapter also discusses ArcGIS Fieldmaps which is a combination of many other ArcGIS products and can be used to help plan, track, and understand data as well as help with the process of capturing data of field workflow. Fieldmaps can utilize many different apps and technologies such as AR and VR in its creation of an interactive map.
