What are web maps in ArcGIS Online composed of?

• A. 2D maps that are made up of web layers that can be shared, edited, and displayed online.
• B. 3D representations of geographic data alone.
• C. A collection of all web apps available in the online environment.
• D. Static images of geographical features.

Answer: (A)

Web maps in ArcGIS Online are indeed composed of 2D maps that consist of various web layers. These layers can include base maps, feature layers, and other data sources that can be shared, edited, and displayed online. This functionality allows users to interact with dynamic content, making it possible to visualize geographical information in a meaningful way. The ability to incorporate multiple layers allows for a rich understanding of spatial relationships and patterns. Users can add various types of data—such as point data, lines, and polygons—as well as raster data, enabling a comprehensive view of the data being analyzed. In contrast, the other options do not accurately define web maps. For instance, while 3D representations of geographic data are possible in ArcGIS, they do not encompass the full range of capabilities offered by web maps, which are primarily 2D in nature. A collection of web apps does not represent the essence of what a web map is, as web maps focus specifically on the visualization of layered spatial data rather than applications. Lastly, static images of geographical features do not capture the interactive and dynamic nature of web maps, which allows users to engage with the data through pan, zoom, and data querying functionalities. Thus, option A accurately describes the
