RRANGE

Draw range rings about a given latitude/longitude.

12 to 15 parameters:

  1. Latitude of range ring center point (Degree portion)
  2. Latitude of range ring center point (Minute portion)
  3. Latitude of range ring center point (Seconds portion)
  4. Longitude of range ring center point (Degree portion)
  5. Longitude of range ring center point (Minute portion)
  6. Longitude of range ring center point (Seconds portion)
  7. Angle from north to start of range rings (degs)
  8. Angle from north to end of range rings (degs)
  9. Angular increment used to generate rings (degs)
  10. Range to first ring (nautical miles)
  11. Range to last ring (nautical miles)
  12. Range rings drawn every field 12 nautical miles
  13. [Optional] Tick Mark control parameter
  14. [Optional] Length of tick marks (inches)
  15. [Optional] Control parameter for range ring centers

Example:

RRANGE 38,,,77,,,330,30,1,500,3000,500
Draws range rings from 500 NM to 3000 NM at 500 NM intervals between 330° and 30° centered at 38°N, 77°W.
