Reconstruction of the
2020 Ackling Dyke formation |
|
1. |
| Draw a circle. Draw the horizontal and vertical centerlines.
|
|
2. |
| Construct the inscribed regular 14-sided polygon of circle 1, pointing up.
|
|
3. |
| Draw the fourteen rays of polygon 2, from the center to the angular points. Number these rays clockwise 1 - 14, starting at the top.
|
|
4. |
| Draw the connecting line between the righthand intersection of circle 1 and the horizontal centerline, and the intersection of circle 1 and ray 3 nr. 1.
|
|
5. |
| Construct a circle concentric to circle 1, tangent to line 4.
|
|
6. |
| Repeat step 4 thirteen times, with respect to the other rays 3 and corresponding positions, as shown.
|
|
7. |
| Construct a circle centered at the intersection of circle 5 and ray 3 nr. 2, passing through the intersection of line 4 and ray 3 nr. 2.
|
|
8. |
| Copy circle 7 to the upper intersection of circle 1 and the vertical centerline.
|
|
9. |
| Construct a circle concentric to circle 1, tangent to circle 8 at the lower side.
|
|
10. |
| Draw the connecting line between the righthand intersection of circle 1 and the horizontal centerline, and the intersection of circle 9 and ray 3 nr. 14.
|
|
11. |
| Construct a circle concentric to circle 1, tangent to line 10.
|
|
12. |
| Draw the connecting line between the intersections of circle 11 with rays 3 nrs. 1 and 7.
|
|
13. |
| Repeat step 12 six times, with respect to the pairs of rays 3 nrs. 3 and 9, 5 and 11, 7 and 13, 9 and 1, 11 and 3, and 13 and 5.
|
|
14. |
| Circles 1, 5, and 9, and lines 3, 4, 6, 12, and 13, are used for the final reconstruction.
|
|
15. |
| Remove all parts not visible within the formation itself.
|
|
16. |
| Colour all areas corresponding to standing...
|
|
17. |
| ...or to flattened crop, and finish the reconstruction of the 2020 Ackling Dyke formation.
|
|
18. |
| The final result, matched with the aerial image.
