Both the true Hilbert curve and its discrete approximations are useful because they give a mapping between 1D and 2D space that preserves locality fairly well. This means that two data points which are close to each other in one-dimensional space are also close to each other after folding. The converse cannot always be true. Because of this locality property, the Hilbert curve is widely used in computer science. For exam… Web3D Hilbert Curves Properties.
