ELIPSERG

Draw an elliptical arc around a given latitude/longitude (see ELLIPSE).

13 parameters:

  1. Latitude of center point (Degree portion)
  2. Latitude of center point (Minute portion)
  3. Latitude of center point (Seconds portion)
  4. Longitude of center point (Degree portion)
  5. Longitude of center point (Minute portion)
  6. Longitude of center point (Seconds portion)
  7. Semimajor axis (nautical miles)
  8. Semiminor axis (nautical miles)
  9. Orientation of ellipse from north (degrees)
  10. Angle from north to start of ellipse (degrees)
  11. Angle from north to end of ellipse (degrees)
  12. Angular increment to generate ellipse (degrees)
  13. Control parameter for ellipse centers
Example:

ELIPSERG 30,,,-120,,,500,300,45,0,360,1,0
Draws a complete ellipse measuring 500 by 300 miles inclined 45° at 30°N, 120°W.
