|
|
6. |

|
|
10. |

|
|
11. |
| Draw the connecting line between the lefthand and righthand intersections (tangent points) of octagon 6 and circle 7, just above the horizontal centerline.
|
|
12. |
| Construct a circle concentric to circle 7, tangent to line 11.
|
|
13. |
| Construct a circle centered at the lower intersection of circle 8 and the vertical centerline, tangent to circle 12 at the upper side.
|
|
14. |
| Copy circle 13 to the center of circle 7.
|
|
15. |
| Construct the circumscribed octagon of circle 14, pointing up.
|
|
16. |
| Construct the circumscribed circle of octagon 15.
|
|
17. |
| Construct a circle centered at the upper intersection of circle 7 and the vertical centerline, tangent to circle 9 at the lower side.
|
|
18. |
| Draw the connecting line between two intersections (tangent points) of octagon 6 and circle 7, one at the righthand side just above, the other at the lefthand side just below the horizontal centerline.
|
|
19. |
| Copy circle 17 to the upper righthand intersection of circle 16 and line 18.
|
|
20. |
| Construct a circle centered at the upper righthand intersection of circle 19 and line 18, passing through the center of circle 17.
|
|
21. |
| Construct a circle centered at the lower lefthand intersection of circle 16 and line 18, tangent to circle 14 at the near side.
|
|
22. |
| Copy circle 21 to the intersection of circle 20 and line 18.
|
|
23. |
| Construct a circle concentric to circle 20, tangent to circle 22 at the lower lefthand side.
|
|
24. |
| Construct a circle concentric to circle 7, passing through the upper intersection of circle 23 and the vertical centerline.
|
|
25. |
| Construct a circle concentric to circle 7, tangent to circle 19 at the upper righthand side.
|
|
26. |
| Construct the inscribed octagon of circle 25, with an angular point coincident with the center of circle 20.
|
|
27. |
| Copy circles 20 and 23 together seven times, to the other angular points of octagon 26.
|
|
28. |
| Circles 7, 9, 10, 12, 14, 16, 20, 23, 24, and 27, are used for the final reconstruction.
|
|
29. |
| Remove all parts not visible within the formation itself.
|
|
30. |
| Colour all areas corresponding to standing...
|
|
31. |
| ...or to flattened crop, and finish the reconstruction of the 2020 Norton Plantation formation.
|
|
32. |
| The final result, matched with the aerial image.
