1. to convert or encode map data that are represented in analog form into digital information of x and y coordinates 2. to employ a digitizing tablet to record x,y or x,y,z values for map features —note lines are traced to define their shape; a digitizer button, pressed periodically along the line, records x,y coordinates; a digitized line is therefore a series of x,y coordinates —see digitizer, gap, scanningThis definition last updated 10/25/2008
