ArcGIS Online Basics Which of the following best describes ArcGIS Online? A desktop-based geographic information system A cloud-based geographic information system A localized geographic information system A mobile device-based geographic information system - ✔✔A cloud-based geographic information system Which of the following best describes an ArcGIS Online organization? - A desktop application for an organization to access local geospatial data - A method of organizing or arranging maps, scenes, apps, layers, and other content in ArcGIS Online; this may involve groups, folders, and schemas - A discrete virtual space within the ArcGIS Online cloud that gives an organization the ability to manage content and foster collaboration - The organization that hosts ArcGIS Online; this includes location of servers, administrators, and management - ✔✔A discrete virtual space within the ArcGIS Online cloud that gives an organization the ability to manage content and foster collaboration Which of the following is listed in your ArcGIS profile? - A phone number - Any private content - A bio - Level of access - ✔✔A bio Which of the following capabilities are available to a user with public access to ArcGIS Online? *Choose two.* - Create groups - Use Esri proprietary content such as ArcGIS Living Atlas of the World - Share content within an organization - Create web maps - ✔✔- Create groups - Create web maps How are *layers* important and used in ArcGIS Online? - ✔✔Layers are one of the primary ways that you work with geographic data in ArcGIS Online. All web maps and scenes include layers. Each layer references a dataset and specifies how that dataset is portrayed using symbols and text labels. Layers are the foundation for all web maps and scenes. When a layer is added to a map or scene, it functions as either a basemap layer or an operational layer. How are *Web Maps* important and used in ArcGIS Online? - ✔✔Web maps are 2D maps made up of web layers that can be shared, edited, and displayed online. They are a core piece of content in ArcGIS Online that can be used across the ArcGIS platform. How are *Web Scenes* important and used in ArcGIS Online? - ✔✔Web scenes are similar to web maps, except that they display 3D geographic data and phenomena. Layers can be mapped with 3D symbology. How are *Web Apps* important and used in ArcGIS Online? - ✔✔Web apps allow you to control how users interact with web maps and scenes. They provide a more focused experience as well as the opportunity for more context and utility. Users can create their own web apps, even if they have no programming experience. How are *Files* important and used in ArcGIS Online? - ✔✔Common types of files that are shared through ArcGIS Online include reports (PDFs), CSV files, and shapefiles. CSV files and shapefiles can be made into layers. What are *Basemap Layers*? - ✔✔Basemap layers are static tiled layers such as imagery, territorial boundaries, or roads that provide geographic context. What are *Operational Layers*? - ✔✔The layers drawn on top of the basemap can be features or imagery and are called operational layers. Operational layers are the layers that you interact with. Interactions include viewing attribution information, editing features, and performing analysis. "Operational" and "Basemap" are ways to classify layers according to their use, what is another way to classify layers? - ✔✔By how their data is structured. Two common hosted layer types are *feature layers* and *tile layers*. Describe the *feature layer* layer type: - ✔✔A feature layer is a grouping of similar geographic features, for example, buildings, parcels, cities, roads, or earthquake epicenters. Features can be points, lines, or polygons (areas). Feature layers display pop-up windows with tabular information for each feature or location and are used as operational layers. Describe the *tile layer* layer type: - ✔✔A tile is a collection of prerendered images or quick-torender vectors that can be rapidly displayed. When displaying prerendered imagery, tile layers may display elevation, aerial photography, or historic maps. Tile layers are often used as basemap layers. When tile layers are used as basemap layers, they will often omit any pop-up interactivity. What is an ArcGIS Online Item Page? - ✔✔Whether it is a layer, map, scene, or app, *all ArcGIS content has an item page* that describes the piece of content: who made it, when it was made, and how it is used. A thorough and complete item page often indicates that the source data or content is high quality. No or incomplete metadata often indicates derivative or incomplete content or data. Where in the item page for a layer would you find the source of the layer's data?
