Reconstruction of the 2021 Rodfield Lane formation | ||
| 1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines. |
| 2. |
| Construct the inscribed regular 16-sided polygon of circle 1, pointing up. Number the angular points clockwise 1-16, starting at the top. |
| 3. |
| Draw the connecting line between angular points nrs. 2 and 5. |
| 4. |
| Draw the connecting line between angular points nrs. 3 and 16. |
| 5. |
| Construct a circle centered at angular point nr. 1, passing through the intersection of lines 3 and 4. |
| 6. |
| Copy circle 5 to the center of circle 1. |
| 7. |
| Draw the connecting line between the center of circle 5 and its lefthand intersection with circle 1. |
| 8. |
| Draw a line from the center of circle 1 to the midpoint of line 7, and extend this line upto circle 5. |
| 9. |
| Construct a line from the intersection of circle 1 and line 8, perpendicular to this line and extending to its intersection with the vertical centerline. |
| 10. |
| Construct a circle concentric to circle 1, passing through the intersection of line 9 and the vertical centerline. |
| 11. |
| Construct a circle centered at the intersection of lines 3 and 4, tangent to circle 10 at the upper righthand side. |
| 12. |
| Copy circle 11 to the center of circle 1. |
| 13. |
| Draw two lines, from the upper intersection of circle 6 and the vertical centerline to angular points nrs. 2 and 16. |
| 14. |
| Copy lines 13 seven times, from the other corresponding points at circle 6 to the other corresponding even numbered angular points, as shown. |
| 15. |
| Construct a circle concentric to circle 1, tangent to line 3. |
| 16. |
| Draw eight rays of polygon 2, from the center to the even numbered angular points. |
| 17. |
| Draw the connecting line between angular point nr. 2 and the intersection of circle 15 and ray 16 nr. 14. |
| 18. |
| Draw the connecting line between angular point nr. 16 and the intersection of circle 15 and ray 16 nr. 4. |
| 19. |
| Copy lines 17 and 18 seven times, to the other corresponding angular points and intersections, as shown. |
| 20. |
| Draw two lines, from the intersection of lines 17 and 18 to the intersections of circle 12 with rays 16 nrs. 2 and 16. |
| 21. |
| Copy lines 20 seven times, between the other corresponding intersections, as shown. |
| 22. |
| Draw the connecting line between angular points nrs. 2 and 15. |
| 23. |
| Copy lines 4 and 22 seven times, between the other corresponding angular points, as shown. |
| 24. |
| Circle 10, and lines 4, 13, 14, 17, 18, 19, 20, 21, 22, and 23, are used for the final reconstruction. |
| 25. |
| Remove all parts not visible within the formation itself. |
| 26. |
| Colour all areas corresponding to standing... |
| 27. |
| ...or to flattened crop, and finish the reconstruction of the 2021 Rodfield Lane formation. |
| 28. |
| The final result, matched with the aerial image. |
