Which of the following are common data formats supported in ArcGIS?

JPEG raster datasets are indeed a common data format supported in ArcGIS, primarily because they are frequently used for aerial imagery and other raster applications. JPEG is a widely accepted format for storing and sharing images due to its compression capabilities, making it a practical choice for visualizing spatial data. Since ArcGIS often involves the analysis and manipulation of geospatial data, having the ability to import and work with JPEG files is essential. Various raster datasets can be converted, analyzed, and displayed in ArcGIS, which enhances its functionality for users dealing with spatial data.

In contrast, formats like PowerPoint, Excel files, and Word documents are not primarily designed for geospatial data management and will not have the same level of native support within ArcGIS for spatial analysis. While Excel files can occasionally be used for tabular data that may include coordinates, they do not represent raster or vector data formats inherently suited for GIS applications in the same way JPEG files do.
