A method, system, and article of manufacture provide the ability to redline or mark up geographic information on a personal digital assistant (PDA). An application on the PDA is configured to obtain map data from a server and display the map data on a screen of the PDA. Markup data is obtained from a user through a stylus that is used to markup the map displayed on the PDA. A file comprised of the markup data is created and then uploaded from the PDA to the server. Accordingly, the markup data comprises a markup layer that is stored locally on the PDA and uploaded (synchronized) with the server automatically when a list of a set of maps is updated.
