A heading is the angular direction you are going or plan to go. A bearing is the angular direction of somewhere else from your current position. The angular direction is measured as either relative to true North or magnetic North corrected for local magnetic variation. There is also generally a difference among course, heading, and track. -- penninojim@yahoo.com
