Reconstruction of the 2016 Großziethen (Germany) formation | ||
1. | ![]() | Draw a circle. Draw the horizontal and vertical centerlines. |
2. | ![]() | Copy circle 1 two times, to the righthand and upper intersections of circle 1 and the horizontal and vertical centerlines. |
3. | ![]() | Draw the connecting line between the mutual intersections of circles 2. |
4. | ![]() | Construct the inscribed dodecagon (regular 12-sided polygon) of circle 1, with one angular point on line 3. |
5. | ![]() | Construct the inscribed circle of dodecagon 4. |
6. | ![]() | Construct a circle, passing through the upper and adjacent righthand intersections of dodecagon 4 and circle 5, and tangent to line 3. |
7. | ![]() | Copy circle 6 to the center of circle 1. |
8. | ![]() | Draw the twelve rays of dodecagon 4, from the center to the angular points. |
9. | ![]() | Construct the inscribed hexagon (regular 6-sided polygon) of circle 5, pointing up. |
10. | ![]() | Construct a "two-points" circle (defined by the two end-points of a centerline) between the upper angular point of hexagon 9 and the lower intersection of circle 7 and the vertical centerline. |
11. | ![]() | Copy circle 10 five times, by repeating step 10 with respect to the other angular points of hexagon 9. |
12. | ![]() | Construct the inscribed hexagon of circle 5, pointing to the right. |
13. | ![]() | Construct a "two-points" circle between the righthand angular point of hexagon 12 and the lefthand intersection of circle 7 and the horizontal centerline. |
14. | ![]() | Copy circle 13 five times, by repeating step 13 with respect to the other angular points of hexagon 12. |
15. | ![]() | Circles 1, 5, 7, 10, 11, 13, and 14, are used for the final reconstruction. |
16. | ![]() | Remove all parts not visible within the formation itself. |
17. | ![]() | Colour all areas corresponding to standing... |
18. | ![]() | ...or to flattened crop, and finish the reconstruction of the 2016 Großziethen (Germany) formation. |
19. | ![]() | The final result, matched with the aerial image. |
