Reconstruction of the 2002 Sompting formation | ||
1. | ![]() | Draw a square. |
2. | ![]() | Construct the inscribed circle of square 1. Draw the horizontal and vertical centerlines. |
3. | ![]() | Construct the circumscribed circle of square 1. |
4. | ![]() | Construct the inscribed hexagon (regular 6-sided polygon) of circle 2. |
5. | ![]() | Construct the inscribed circle of hexagon 4. |
6. | ![]() | Construct the inscribed hexadecagon (regular 16-sided polygon) of circle 2. Number the angular points counterclockwise, starting with nr. 0 from the rightmost angular point. |
7. | ![]() | Draw the connecting line between angular points nr. 1 and nr. 12 of hexadecagon 6. |
8. | ![]() | Construct a circle concentric to circle 2, tangent to line 7. |
9. | ![]() | Copy circle 3 to angular point nr. 0 of hexadecagon 6. |
10. | ![]() | Copy circle 3 to angular point nr. 8 of hexadecagon 6. |
11. | ![]() | Copy circle 3 to angular point nr. 15 of hexadecagon 6. |
12. | ![]() | Copy circle 3 to angular point nr. 7 of hexadecagon 6. |
13. | ![]() | Draw the connecting line between angular points nr. 3 and nr. 12 of hexadecagon 6. |
14. | ![]() | Construct a circle concentric to circle 2, tangent to line 13. |
15. | ![]() | Copy circle 14 twice, to the outermost intersections of circles 9 and 11 and of circles 10 and 12. |
16. | ![]() | Copy circle 14 another two times, to the lower intersection of circle 9 and rightmost circle 15, and to the upper intersection of circle 10 and leftmost circle 15. |
17. | ![]() | Only circles 2, 5, 8, 9, 10, 11, 12 and 16 are needed for the reconstruction. |
18. | ![]() | Leave out all parts not visible in the formation. |
19. | ![]() | Colour green all areas corresponding to flattened crop. This finishes the reconstruction of the 2002 Sompting formation. |
20. | ![]() | The final result, matched with the aerial image. |
