Reconstruction of the
2019 Belmore Lane formation |
|
1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines.
|
|
2. |
| Construct two inscribed squares of circle 1, one pointing to the right, one with horizontal and vertical sides.
|
|
3. |
| Construct the inscribed circle of squares 2.
|
|
4. |
| Draw eight rays of circle 1 from its center to the angular points of squares 2.
|
|
5. |
| Construct a "two-points" circle (defined by the two end-points of a centerline) between the intersections of circles 1 and 3 and the upper righthand ray 4.
|
|
6. |
| Copy circle 5 to the center of circle 1.
|
|
7. |
| Construct a "two-points" circle between the righthand intersections of circles 1 and 6 with the horizontal centerline.
|
|
8. |
| Copy circle 7 to the center of circle 1.
|
|
9. |
| Construct a circle concentric to circle 1, passing through the center of circle 7.
|
|
10. |
| Construct the inscribed octagon (regular 8-sided polygon) of circle 9, pointing to the right.
|
|
11. |
| Copy circle 7 seven times, to the other angular points of octagon 10. Number these circles counterclockwise 1 - 7, starting at the upper righthand one.
|
|
12. |
| Draw four pairs of parallel lines, one pair between the righthand intersections of circles 11 nrs. 1 and 7 and the lefthand intersections of circles 11 nrs. 3 and 5, with circle 9. The other three pairs between corresponding intersections of circles 7 and 11 with circle 9. See detail.
|
|
|
|
13. |
| Draw a line, tangent to circles 11 nrs. 1 and 3, at the upper sides.
|
|
14. |
| Construct a circle concentric to circle 1, tangent to line 13.
|
|
15. |
| Construct the circumscribed square of circle 14, pointing to the right.
|
|
16. |
| Construct the circumscribed circle of square 15.
|
|
17. |
| Construct the circumscribed square of circle 16, pointing to the right.
|
|
18. |
| Construct the circumscribed circle of square 17.
|
|
19. |
| Copy circle 5 to the intersection (tangent point) of circle 7 and the upper righthand side of square 15.
|
|
20. |
| Construct a circle concentric to circle 1, tangent to circle 19 at the far side.
|
|
21. |
| Construct a circle concentric to circle 1, passing through the righthand intersection of circles 11 nrs. 1 and 7.
|
|
22. |
| Copy circle 21 to the righthand angular point of square 15.
|
|
23. |
| Construct a circle concentric to circle 1, tangent to circle 22 at the righthand side.
|
|
24. |
| Circles 6, 7, 8, 9, 11, 18, 20, and 23, and lines 4, and 12, 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 2019 Belmore Lane formation.
|
|
28. |
| The final result, matched with two aerial images.
