Fractal Coastline Generator

Richardson effect — coastline length vs. ruler size

Coastline Parameters

Fractal dim D:
Ruler ε = 1/8:
Ruler ε = 1/32:
Ruler ε = 1/128:
L ∝ ε^(1-D):
Richardson (1961): smaller rulers
measure longer coastlines.
L(ε) ∝ ε^(1−D)

D=1: smooth curve
D=1.25: Norway-like
D=1.52: GB coastline
D→2: fills the plane
