Title: Digital contour line generator
Inventor: THOMPSON ELDON J
IPC: G06T17/05
Filed: 1988-05-25
Granted: 1992-05-19
Abstract: Abstract A contour line generator for identifying and displaying in 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.
