Holy cow! I wish I could understand this, Thank you.
How do they map it out while on the ground though?
To map it out Radish Rose, first you will need a picture taken from above, then you
would need to find the exact center of the circle and start drawing radii or spoke
lines, from the center through the side of the first indent, then to the outside where
it also touches the last indent before the outer circles. Keep drawing lines every time
you another indent, when you finish, you will have 8 lines from the center and 2 wide
spaces, half each space and draw in 2 more lines, your image is complete with 10 lines
exactly the same distance apart.
Now go back to the center and count the segments of each colour using the lines you
drew to be the sections/segments remember the decimal point, so it starts 3.1415etc.
Now you try it, by using the coloured example that I put there.
Good luck.
Mike.
