If a GIS analyst needs to share a presentation of their analysis apart from the map document, what is the most efficient way?

Exporting as a PDF file is the most efficient way for a GIS analyst to share a presentation of their analysis apart from the map document. When a map is exported to a PDF, it retains the visual quality and layout of the original map, making it easy for recipients to view and interact with the presentation material without requiring specific GIS software. PDFs can include various components such as text, graphics, and embedded links, providing a comprehensive platform for analysis results that is accessible across different devices and operating systems.

Other delivery methods like creating web maps or sharing via ArcGIS Online may involve additional steps such as setting up appropriate permissions, which could complicate the sharing process. While saving as a local image file can provide a quick reference to a map, it does not carry any additional contextual information or interactivity that a PDF could offer, making it less suitable for detailed presentations. Thus, exporting as a PDF serves as an effective means of communicating analysis results succinctly and professionally.
