Reconstruction of the
2020 Roundway formation

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

2. Copy circle 1 to its upper intersection with the vertical centerline.

3. Copy circle 1 to its lower intersection with the vertical centerline.

4. Draw the connecting line between the righthand intersections of circle 1 with circles 2 and 3.

5. Construct a "two-points" circle (defined by the two end-points of a centerline) between the righthand intersection of circle 1 and the intersection of line 4 with the horizontal centerline.

6. Copy circle 5 to the center of circle 1.

7. Construct a circle concentric to circle 5, tangent to circle 6 at the righthand side.

8. Construct a circle concentric to circle 7, tangent to circle 6 at the lefthand side.

9. Copy circle 5 to the lefthand intersection of circle 1 and the horizontal centerline.

10. Construct a circle centered at the righthand intersection of circle 9 and the horizontal centerline, tangent to circle 8 at the lefthand side.

11. Construct a circle concentric to circle 10, tangent to circle 7 at the lefthand side.

12. Copy circle 5 to the upper intersection of circle 6 and the vertical centerline.

13. Construct a circle concentric to circle 2, tangent to circle 12 at the upper side.

14. Copy circle 5 to the lower intersection of circle 6 and the vertical centerline.

15. Construct a circle concentric to circle 3, tangent to circle 14 at the lower side.

16. Construct a circle concentric to circle 2, tangent to circle 9 at the upper righthand side.

17. Construct a circle concentric to circle 2, tangent to circle 9 at the lower lefthand side.

18. Construct a circle concentric to circle 3, tangent to circle 9 at the lower righthand side.

19. Construct a circle concentric to circle 3, tangent to circle 9 at the upper lefthand side.

20. Copy circle 5 to the center of circle 2.

21. Construct a circle concentric to circle 7, tangent to circle 20 at the lower righthand side.

22. Construct a circle concentric to circle 7, tangent to circle 20 at the upper lefthand side.

23. Construct a circle concentric to circle 10, tangent to circle 20 at the lower lefthand side.

24. Construct a circle concentric to circle 10, tangent to circle 20 at the upper righthand side.

25. Construct a circle centered at the righthand intersection of circles 16 and 18, tangent to circle 23 at the righthand side.

26. Construct a circle concentric to circle 25, tangent to circle 24 at the righthand side.

27. Construct a circle centered at the lefthand intersection of circles 16 and 18, tangent to circle 22 at the lefthand side.

28. Construct a circle concentric to circle 27, tangent to circle 21 at the lefthand side.

29. Construct a circle concentric to circle 2, tangent to circle 19 at the upper side.

30. Construct a circle concentric to circle 3, tangent to circle 17 at the lower side.

31. Circles 2, 3, 7, 8, 10, 11, 13, 15, 16, 17, 18, 19, 21, 22, 23, 24, 25, 26, 27, 28, 29, and 30, are used for the final reconstruction.

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

33. Colour all areas corresponding to standing...

34. ...or to flattened crop, and finish the reconstruction of the 2020 Roundway formation.

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