2024 Normanton Down Barrows formation
|
Reconstruction of the 2024 Normanton Down Barrows formation | ||
| 1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines. |
| 2. |
| Construct the inscribed square of circle 1, pointing up. |
| 3. |
| Construct the inscribed circle of square 2. |
| 4. |
| Construct the "two-points" circle (defined by the two end-points of a centerline) between the upper righthand intersection of square 2 and circle 3 (tangent point) and the righthand angular point of square 2. |
| 5. |
| Copy circle 4 four times, to the angular points of square 2. |
| 6. |
| Construct a circle centered at the lefthand intersection of circle 4 and the horizontal centerline, tangent to circle 3 at the righthand side. |
| 7. |
| Copy circle 6 four times, to the angular points of square 2. |
| 8. |
| Draw the connecting line between the righthand intersections of the righthand circles 5 and 7 with the horizontal centerline. Divide this line into three equal parts. |
| 9. |
| Construct two circles concentric to the righthand circle 5, passing through division nodes 8. |
| 10. |
| Copy circles 9 three times, to the centers of the other circles 5. |
| 11. |
| Construct the "two-points" circle between the lefthand intersections of the righthand circle 7 and the inner circle 9 with the horizontal centerline. |
| 12. |
| Copy circle 11 to the center of inner circle 9. |
| 13. |
| Construct a circle concentric to circle 1, tangent to circle 12 at the lefthand side. |
| 14. |
| Construct the circumscribed square of circle 13, with horizontal and vertical sides. |
| 15. |
| Construct three circles centered at the righthand intersection of the righthand circle 7 and the horizontal centerline, tangent to circles 9 and the righthand circle 5 at the righthand sides. |
| 16. |
| Copy circles 15 four times, to the angular points of square 14. |
| 17. |
| Construct three parallel lines, parallel to the upper side of square 14, tangent to the upper two sets of circles 16 at the upper sides, as shown. |
| 18. |
| Repeat step 17 three times, with respect to the other sides of square 14 and corresponding sets of circles 16, as shown. |
| 19. |
| Circles 5, 7, 9, 10, and 16, square 14, and lines 17, and 18, are used for the final reconstruction. |
| 20. |
| Remove all parts not visible within the formation itself. |
| 21. |
| Colour all areas corresponding to standing... |
| 22. |
| ...or to flattened crop, and finish the reconstruction of the 2024 Normanton Down Barrows formation. |
| 23. |
| The final result, matched with two aerial images. |
