  • WebAppBuilder and Experience Builder are intuitive what-you-see-is-what-you-get builders that allow you to create 2D and 3D web apps without writing a single line of code. They share a similar workflow for creating web apps and they have the following key features: they create pure HTML and JavaScript apps that are cross platform, they use responsive web design technologies to create web apps that work well on desktops, tablets, and smartphones, they include numerous out-of-the-box widgets that can be flexibly remixed and configured, they include a collection of configurable themes or templates so you can customize the look and feel of the apps, and they provide extensible frameworks for developers to create custom widgets, themes, or templates. 
  • These aspects are ONLY available through Experience Builder: provides flexible layouts so you can build apps that are map centric or non-mapcentric and can display them on a fixed or scrolling screen and on single or multiple pages, it was built with a mobile-first design, it can integrate both 2D and 3D content within one app, and it adds action triggers so you can make a widget respond according to actions that the other widget performs. 
  • Widgets are typically JavaScript or HTML components that encapsulate a set of focused functions. They can be categorized into two groups: Data-independent widgets- Basemap Gallery, Measurement, and Draw widgets are not related to the operational data layers and need little to no configuration. The other group is Data dependent widgets- Query and Chart widgets are related to specific attribute fields of specific layers within the app. They often require detailed configuration.
  • Mobile GIS refers to GIS for use on mobile devices and has the following advantages: Mobility, Location awareness, ease of data collection, near-real-time information, Large volume of users, and versatile means of communication. 
  • Mobile GIS is built on the following technologies: mobile devices such as smartphones and tablets, mobile operating systems (abdroid, IOS, microsoft), wireless communication technology such as bluetooth and wi-fi, and positioning technology like GPS and other approaches. 
  • Mobile GIS is related to many popular types of apps and frontiers, including LBS, VGI, VR, and AR
  • description of an application: The town I am from, Portsmouth, Ohio, had a flood in 1937. I would create a web map of the areas of my city that were affected by flood waters. This would mostly be for history buffs interested in the history of Portsmouth, and for them to see a visual representation of what the city looked like while it was flooded. To do this, I would use Web AppBuilder and upload a map of Portsmouth, Ohio. I would then add some data-dependent widgets and so if someone wanted to hover over a specific building in Portsmouth, the height of the flood water at that specific building would pop up as well as the exact day corresponding to that measurement.
