An ArcGIS user wants to share a map document with a colleague lacking ArcGIS Desktop. What format must the user export to?

Exporting the map document to a PDF format is ideal for sharing with someone who does not have access to ArcGIS Desktop. PDF is widely used for sharing documents because it preserves the layout, fonts, graphics, and colors as intended, regardless of the software or hardware used by the recipient.

Using PDF allows the recipient to view the map document in a manner that closely resembles how it appears in ArcGIS without needing specialized software. Additionally, PDFs can include interactive elements such as hyperlinks and bookmarks, enhancing usability for the viewer.

While other formats like SVG, PNG, and BMP do provide options for image and graphic representation, they do not offer the same level of document fidelity and usability as PDFs for complex map layouts. PNG and BMP are primarily raster image formats that may not support features like text layers or vector graphics, limiting functionality for users who wish to examine the details of the map. SVG, being a vector-based format, is more suitable for web use and may also require specific applications for viewing, making PDF the most accessible choice for sharing comprehensive map documents.
