Reconstruction of the 2015 Blackhorse Lane formation | ||

1. |
Draw a circle. Draw and extend the horizontal and vertical centerlines. | |

2. |
Construct the inscribed hexagon (regular 6-sided polygon) of circle 1, pointing down. | |

3. |
Draw the ray of hexagon 2, from the center of circle 1 to its lower lefthand angular point. | |

4. |
Draw the ray of hexagon 2, from the center of circle 1 to its lower righthand angular point. | |

5. |
Construct a "two-points" circle (defined by the two end-points of a centerline) between the center of circle 1 and its lower intersection with the vertical centerline. | |

6. |
Construct two "two-points" circles, between the center of circle 5 and each of its intersections with the vertical centerline. | |

7. |
Construct three circles concentric to circle 1, passing through the centers of circles 5 and 6. | |

8. |
Copy circles 7 to the lower intersection of circle 1 and the vertical centerline. | |

9. |
Draw three parallel lines, from the intersections of circles 7 and line 3 to the intersections of circles 8 and the lower righthand side of hexagon 2. | |

10. |
Draw three parallel lines, from the intersections of circles 7 and line 4 to the intersections of circles 8 and the lower lefthand side of hexagon 2. | |

11. |
Draw a line from the center of circle 1 to its lower intersection with the vertical centerline. | |

12. |
Draw three vertical lines from the intersections of lines 9 and line 3 to the intersections of lines 10 and the lower lefthand side of hexagon 2. | |

13. |
Draw three vertical lines from the intersections of lines 10 and line 4 to the intersections of lines 9 and the lower righthand side of hexagon 2. | |

14. |
Draw a line from the center of circle 1 to the intersection of the upper line 9 and the middle line 10. | |

15. |
Construct a circle centered at the intersection of the upper line 10 and line 14, tangent to the innermost circle 7 at the lower righthand side. | |

16. |
Copy circle 15 to the righthand intersection of circle 1 and the horizontal centerline. | |

17. |
Construct a circle concentric to circle 1, tangent to circle 16 at the righthand side. | |

18. |
Construct a "two-points" circle between the center of circle 15 and its lower intersection with line 14. | |

19. |
Copy circle 18 to the lower righthand angular point of hexagon 2. | |

20. |
Copy circle 18 to the center of circle 1. | |

21. |
Draw a line parallel to line 4, tangent to circles 19 and 20 at the lower lefthand sides. | |

22. |
Copy circle 18 to the lower angular point of hexagon 2. | |

23. |
Draw a line parallel to the lower righthand side of hexagon 2, tangent to circles 19 and 22 at the upper lefthand sides. | |

24. |
Circles 1 and 17, hexagon 2, and lines 3, 4, 9, 10, 11, 12, 13, 21, and 23, are used for the final reconstruction. | |

25. |
Remove all parts not visible within the formation itself. | |

26. |
Colour all areas corresponding to standing... | |

27. |
...or to flattened crop, and finish the reconstruction of the 2015 Blackhorse Lane formation. | |

28. |
The final result, matched with the aerial image. |
