Reconstruction of the
2020 Smeathe's Plantation formation

1. Draw a circle. Draw the horizontal and vertical centerlines.

2. Construct the inscribed regular 18-sided polygon of circle 1, pointing up.

3. Draw the eighteen rays of polygon 2, from the center to the angular points. Number these rays, as well as the angular points, clockwise, 1 - 18, starting at the top.

4. Draw the connecting line between angular points (of polygon) 2 nrs. 3 and 17.

5. Construct a circle concentric to circle 1, tangent to line 4.

6. Construct a "two-points" circle (defined by the two end-points of a centerline) between angular points 2 nrs. 4 and 5.

7. Construct a circle concentric to circle 6, passing through the intersection of ray 3 nr. 1 and line 4.

8. Draw the connecting line between angular points 2 nrs. 1 and 7.

9. Construct a circle concentric to circle 1, passing through the intersection of ray 3 nr. 3 and line 8.

10. Draw the connecting line between the intersections of circle 9 with rays 3 nrs. 1 and 7.

11. Construct a circle concentric to circle 1, passing through the intersection of ray 3 nr. 3 and line 10.

12. Copy circle 6 to the center of circle 1.

13. Construct a circle centered at the righthand intersection of circle 11 and the horizontal centerline, tangent to circle 12 at the righthand side.

14. Copy circle 13 to the center of circle 1.

15. Construct a circle centered at the intersection of ray 3 nr. 1 and line 4, passing through the intersection of circle 9 and ray 3 nr. 5.

16. Copy circle 15 to the center of circle 1.

17. Construct a circle centered at the intersection of ray 3 nr. 1 and line 4, tangent to circle 16 at the upper side.

18. Copy circle 17 two times, to its lefthand and righthand intersections with circle 5.

19. Repeat step 18 eight times, with respect to rays 3 nrs. 3, 5, 7, 9, 11, 13, 15, and 17.

20. Copy circle 17 to its own upper intersection with ray 3 nr. 1.

21. Construct a circle concentric to circle 1, tangent to circle 20 at the upper side.

22. Copy circle 17 to the intersection of ray 3 nr. 10 and circle 21.

23. Copy circle 17 two times, to the lefthand and righthand intersections of circle 22 with circle 21.

24. Repeat step 23 eight times, with respect to rays 3 nrs. 2, 4, 6, 8, 12, 14, 16, and 18.

25. Copy circle 7 seventeen times, to the corresponding positions (mid-points) of the other sides of polygon 2.

26. Circles 1, 5, 7, 9, 11, 12, 14, 16, 18, 19, 23, 24, and 25, are used for the final reconstruction.

27. Remove all parts not visible within the formation itself.

28. Colour all areas corresponding to standing...

29. ...or to flattened crop, and finish the reconstruction of the 2020 Smeathe's Plantation formation.

30. The final result, matched with the aerial image.
