In ArcGIS Pro, what is the purpose of a "Map Frame"?

A "Map Frame" in ArcGIS Pro serves the specific function of displaying a map or layout within a layout view. It acts as a container that shows the contents of a map view in a more controlled context, allowing users to focus on specific areas or details of their geographic data as they compile their overall output, such as a printed map or a PDF.

In a layout, multiple map frames can be utilized to show different views or aspects of the same dataset or whether to demonstrate variations in data presentations. This feature is particularly valuable when creating complex layouts that include multiple maps, providing flexibility and organization in how maps are presented together.

This design enhances the user's ability to create professional-quality cartographic outputs by enabling precise positioning and sizing of the map while integrating with other elements like titles, legends, and scale bars within the layout. The focus is on visual communication of geospatial information in an easily digestible format.

Exploring the other options, displaying a grid of coordinates would pertain to a separate functionality, often associated with coordinate systems and reference grids; providing a legend is related to explanatory features for the map but does not serve as a display function itself; and capturing user input could involve interactive tools but falls outside the specific role of what a Map Frame
