Coverings of a fractal curve (here the coast of Great Britain), in three different ways. From left to right : Maximum number of disjoint disks of radius r, centered on the set (center is on the coast). Minimum number of disks of radius r covering the set. Squares of the grid (mesh) of size r containing the set. These coverings are equivalent for the calculation of the Minkowski dimension and yield the same value .
