WebA space-filling curve (SFC) is a way of mapping a multi‐dimensional space into a one‐dimensional space. It acts like a thread that passes through every cell element (or pixel) in the multi‐dimensional space so that every cell is visited exactly once. Thus, a space-filling curve imposes a linear order of points in the multi‐dimensional space.
