ArcGIS Online Basics Flashcards
Define basic ArcGIS Online terms and distinguish basic ArcGIS Online uses and capabilities
This pertains to Web Layers
What is a tile layer?
A collection of prerendered images or quick-to-render vectors that can be rapidly displayed.
An image that can be quickly displayed that can show vector data; mosaic
Commonly used for basemaps and omits pop-ups; loads as the user pans through the map; better for larger datasets
This pertains to Web Layers
What is a map image layer?
A collection of map cartography based on vector data. The image is static, but content can be dynamic and changed and is rendered on the fly.
Image that is dynamically updated; a map that can’t be broken into tiles
Can be slower than tile layers
This pertains to Web Layers
What is an imagery layer?
A collection of map cartography based on raster data.
Specifically designed to display aerial or satellite images
Think remote sensing; Focus is on displaying real-world conditions as captured by sensors
This pertains to Web Layers
What is an elevation layer?
A collection of prerendered cached image tiles for single-band or elevation data and is used to show terrain.
Raster datasets that show topography and DEM
Can also be represented via contour lines; vertical dimension of Earth’s surface
This pertains to Web Layers
What is a scene layer?
A collection of 3D feature objects and elevation values.
Efficiently visualize large amounts of 3D content
Can be represented as a 3D object, integrated mesh (texture and shape), points, BIM (building information modeling; interior and exterior of buildings), and point clouds (LiDAR/vegetation)
This pertains to Web Layers
What is a table layer?
A collection of rows and columns in which each row, or record, represents a single entity; not drawn on a map.
Think CSVs/speadsheets/attribute table
A non-spatial dataset organized into a tabular format. Includes some sort of geospatial data in order to be used in mapping.
Where are three places you can get layers from?
ArcGIS Online (thru your organization, Living Atlas), Local files (CSV or shapefiles), or as Sketch Layers which are drawn on maps via the map viewer.
What is private sharing?
Only the content creator and the administrator can see private content. This is appropriate for projects under construction and aren’t ready to be published.
What is group sharing?
Content that is related to a particular theme or area of interest is shared within groups of the same theme or expertise. Members of the groups can collaborate. Memberships for each group can be open or restricted. Items can be shared publicly or solely within the organization.
Cross-department collaboration with restricted items to that group.
What is organization sharing?
All members of an organization can see the content. Content can be shared across the board or within groups. Allows for seamless collaboration, controlled access to data and resources.
What is public sharing?
Anyone with internet access has the ability to login and access publicly shared content. This is ideal for government and open-source. Content can be shared anywhere within the organization, but so long as it’s toggled to public, then anyone can have access.
This is an ArcGIS Online capability
What is smart mapping?
ArcGIS Online will automatically identify a field to symbolize and make suggestions on symbology.
Think of AI enabled cartography
This is an ArcGIS Online capability
What is analysis?
Tools inside ArcGIS Online that helps users find patterns, answer questions, and gain insights.
This is an ArcGIS Online capability
What is sharing and collaboration?
Where content can be shared with the whole organization or limited to groups. Those who have access to this content can edit it at the discretion of the creator. Content can be shared publicly and embedded into websites.
What is a public user?
A public account that is free for personal, noncommercial use. This account type allows people to create and share content, with limits on usage. You can use a Social login.
