Abstract
A contour line generator for identifying and displaying real time elevation contour lines for use with a moving map display. A plurality of data points neighboring a selected data point are compared to determine the presence or absence of a contour line. An average elevation is computed and applied to address a contour memory, having stored therein the elevations at which contour lines are desired to be displayed. The resultant logic signals are applied dynamically to override normal display data when a contour line is to be generated. The system provides programability for flexibility in modifying contour line intervals.
