2007 Westwoods (2) formation

Reconstruction of the 2007 Westwoods (2) formation | ||
| 1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines. |
| 2. |
| Construct the circumscribed equilateral triangle of circle 1, pointing up. |
| 3. |
| Copy circle 1 to the intersection of the righthand side of triangle 2 and the horizontal centerline. |
| 4. |
| Construct a circle concentric to circle 1, tangent to circle 3 at the righthand side. |
| 5. |
| Copy circle 1 two times, to both intersections of circle 4 and the horizontal centerline. |
| 6. |
| Construct a circle centered at the upper intersection of circle 1 and the vertical centerline, tangent to circle 3 at the upper lefthand side. |
| 7. |
| Copy circle 6 two times, to the outer intersections of circles 5 and the horizontal centerline, as shown. |
| 8. |
| Construct a "two-points" circle (defined by the end-points of a centerline), defined by the upper intersection of circle 4, and the lower intersection of circle 6, both with the vertical centerline. |
| 9. |
| Construct a circle concentric to circle 8, tangent to circle 1 at the upper side. |
| 10. |
| Copy circle 9 two times, to the outer intersections of circles 7 and the horizontal centerline, as shown. |
| 11. |
| Circles 4, 5, 7 and 10 are used for the final reconstruction. |
| 12. |
| Remove everything not visible in the formation itself. |
| 13. |
| Colour areas with standing... |
| 14. |
| ...or with flattened crop, and finish the reconstruction of the 2007 Westwoods (2) formation. |
| 15. |
| The final result, matched with the aerial image. |
