Reconstruction of the 2001 Browns Lane formation | ||
| 1. | ![]() |
Draw a circle. Draw the horizontal and vertical centerlines. |
| 2. | ![]() |
Divide the circumference of circle 1 into 16 equal parts and draw the rays. |
| 3. | ![]() |
Draw the diagonal connecting the end-point of the horizontal centerline on the right with the end-point of the ray one above the horizontal centerline on the left. |
| 4. | ![]() |
Construct a circle concentric to circle 1 tangent to diagonal 3. |
| 5. | ![]() |
Copy circle 1 to the intersection on the left of circle 4 and the horizontal centerline. |
| 6. | ![]() |
Construct a circle concentric to circle 1 tangent to circle 5 at the near side. |
| 7. | ![]() |
Copy circle 1 four times to the intersections of the horizontal and vertical centerlines and circle 6. |
| 8. | ![]() |
Construct a circle concentric to circle 1 passing through the intersections of circles 7. |
| 9. | ![]() |
Clip off all parts of circles 7 outside circle 8. |
| 10. | ![]() |
Copy circle 1 four times to the intersections of the horizontal and vertical centerlines and circle 8. |
| 11. | ![]() |
Clip off all parts of circles 10 outside circle 6 (at exactly their mutual intersections). |
| 12. | ![]() |
Construct a circle concentric to circle 1 tangent to (the remainders of) circles 10 at the inner sides. |
| 13. | ![]() |
Copy circle 1 four times to the intersections of the horizontal and vertical centerlines and circle 12. |
| 14. | ![]() |
Construct a circle concentric to circle 1 passing through the intersections of circles 13. |
| 15. | ![]() |
Clip off all parts of circles 13 outside circle 14. |
| 16. | ![]() |
Construct a circle with its center on the horizontal centerline on the right tangent to circles 4 (outside) and 12 (inside), as shown. |
| 17. | ![]() |
Copy circle 16 to the center of circle 1. |
| 18. | ![]() |
Circles 1, 4, 6, 8, 12, 14 and 17 and arcs 9, 11 and 15 together form all necessary parts for the reconstruction. |
| 19. | ![]() |
Removing all parts not present finally, and making black all areas corresponding to standing crop, finishes the reconstruction of the 2001 Browns Lane formation. |
| 20. | ![]() |
The final result matched with the aerial image. |
