# How Long Is the Coast of Britain? Statistical Self-Similarity and Fractional Dimension

@article{Mandelbrot1967HowLI, title={How Long Is the Coast of Britain? Statistical Self-Similarity and Fractional Dimension}, author={Benoit B. Mandelbrot}, journal={Science}, year={1967}, volume={156}, pages={636 - 638} }

Geographical curves are so involved in their detail that their lengths are often infinite or, rather, undefinable. However, many are statistically "selfsimilar," meaning that each portion can be considered a reduced-scale image of the whole. In that case, the degree of complication can be described by a quantity D that has many properties of a "dimension," though it is fractional; that is, it exceeds the value unity associated with the ordinary, rectifiable, curves.

How long was the coast of Ireland? Investigating the variation of the fractal dimension of maps over time

- Physics
- 2008

The divider dimensions of a range of maps of Ireland dating from 1567 to 1893 are evaluated, and it is shown that for maps produced before 1650 the fractal dimension of the map can be correlated to…

Global Relief: Evidence of Fractal Geometry

- Physics
- 1994

On the base of a one—degree grid of elevation values lengths of different topographic isolines were computed for seven grades of resolution. It was ascertained that elevation contours have fractal…

THE IMPORTANCE OF PROPER SEQUENCING IN ESTIMATING THE LENGTH AND FRACTAL DIMENSION OF TORTUOUS CURVES

- Business
- 2015

There are several cases when tortuous continuous lines have to be discretized in order to measure length and other related quantities. In this methodological paper, we are going to demonstrate the…

Hortonian scaling and effect of cutoffs on statistics of self‐affine river networks

- Mathematics
- 2009

The planar structure of river networks exhibits fractal properties. In particular, available data indicate a tendency for drainage areas A to be distributed according to a power law; their boundaries…

Introduction to the Properties and Analysis of Fractal Objects, Processes, and Data

- Mathematics, Computer Science
- 1989

This work provides both qualitative and more formal definitions of the fractal dimension and shows how it can be evaluated from experimental data and also shows how a time series can be turned into a geometric object.

How winding is the coast of Britain? Conformal invariance of rocky shorelines

- Mathematics
- 2008

We show that rocky shorelines with fractal dimension 4/3 are conformally invariant curves by measuring the statistics of their winding angles from global high‐resolution data. Such coastlines are…

Complexity and scale in geomorphology: Statistical self-similarity vs. characteristic scales

- Geology
- 1996

Two models of the relationship between complexity and scale of geomorphic lines are compared, one based on statistical self-similarity (in which complexity is invariant for some range of scale), and…

Fractal-Based Description of Urban Form

- Materials Science
- 1987

Fractals, shapes with nonintegral or fractional dimension which manifest similar degrees of irregularity over successive scales, are used to produce a consistent measure of the length of irregular…
