Reconstruction of the 2017 Oliver's Castle formation | ||

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

2. |
Construct the inscribed regular 27-sided polygon of circle 1, pointing down. Number the angular points clockwise 1 - 27, starting from the top. | |

3. |
Draw ray nr. 6 of polygon 2 (from the center to angular point nr. 6). | |

4. |
Draw ray nr. 7 of polygon 2. | |

5. |
Construct a line from the intersection of line 3 and circle 1, perpendicular to the horizontal centerline. | |

6. |
Construct a circle concentric to circle 1, passing through the intersection of lines 4 and 5. | |

7. |
Construct a line from the intersection of line 3 and circle 6, perpendicular to the horizontal centerline. | |

8. |
Construct a circle centered at the intersection of lines 4 and 7, tangent to circle 6 at the righthand side. | |

9. |
Construct a circle concentric to circle 8, tangent to circle 1 at the righthand side. | |

10. |
Copy circles 8 and 9 twenty-six times, to the corresponding positions with respect to the other angular points of polygon 2, as shown. | |

11. |
Circles 1, 6, 8, 9, and 10, are used for the final reconstruction. | |

12. |
Remove all parts not visible within the formation itself. | |

13. |
Colour all areas corresponding to standing... | |

14. |
...or to flattened crop, and finish the reconstruction of the 2017 Oliver's Castle formation. | |

15. |
The final result, matched with the aerial image. |
