2022 Tawsmead Copse formation
|
Reconstruction of the 2022 Tawsmead Copse formation | ||
| 1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines. |
| 2. |
| Draw the connecting line between the lefthand and righthand intersections of circle 1 and the horizontal centerline. |
| 3. |
| Divide line 2 into twentythree equal parts. Number the dividing nodes 1 - 22, from left to right. |
| 4. |
| Construct five circles concentric to circle 1, passing through nodes 3 nrs. 1, 2, 3, 4, and 5. |
| 5. |
| Construct the inscribed regular 23-sided polygon of circle 1, pointing up. Number the angular points, clock-wise, 1 - 23, starting at the top. |
| 6. |
| Draw the connecting line between the center of circle 1 and angular point 5 nr. 2. |
| 7. |
| Construct a "two-points" circle (defined by the two end-points of a centerline) between the center of circle 1 and node 3 nr. 13. |
| 8. |
| Copy circle 7 to angular point 5 nr. 1. |
| 9. |
| Construct a horizontal line, from the lower intersection of circle 8 and the vertical centerline, upto line 6. |
| 10. |
| Construct a circle concentric to circle 1, passing through the intersection of lines 6 and 9. |
| 11. |
| Copy circle 7 to the righthand intersection of circle 10 and the horizontal centerline. |
| 12. |
| Construct six circles concentric to circle 11, passing through nodes 3 nrs. 16, 17, 18, 19, 20, and 21. |
| 13. |
| Copy circle 7 to the lefthand intersection of circle 10 and the horizontal centerline. |
| 14. |
| Construct eight circles concentric to circle 13, passing through nodes 3 nrs. 2, 3, 4, 5, 6, 7, 8, and 9. |
| 15. |
| Construct a "two-points" circle between the center of circle 1 and node 3 nr. 16. |
| 16. |
| Draw the connecting line between the center of circle 1 and angular point 5 nr. 16. Extend this line upto the other side of circle 1. |
| 17. |
| Construct a circle centered at the righthand intersection of circle 1 and the horizontal centerline, passing through node 3 nr. 13. |
| 18. |
| Construct a circle concentric to circle 1, tangent to circle 17 at the righthand side. |
| 19. |
| Extend line 16 further, upto circle 18. |
| 20. |
| Copy circle 15 to the intersection of circle 18 and line 19. |
| 21. |
| Construct a "two-points" circle between the centers of circles 1 and 7. |
| 22. |
| Copy circle 21 two times, to nodes 3 nrs. 5 and 18. |
| 23. |
| Construct two parallel (horizontal) lines, tangent to circles 22 at both sides. |
| 24. |
| Circles 1, 4, 11, 12, 13, 14, and 20, and lines 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 2022 Tawsmead Copse formation. |
| 28. |
| The final result, matched with two aerial images. |
