+Ordinal hashing of multidimensonal data and geographic coordinates via Morton coding / Z-ordering.
+
+In mathematical analysis and computer science, `Z-order`, `Morton-order`, or a `Morton-code` is a function
+which maps multidimensional data to one dimension while preserving locality of the data points.
+It was introduced in 1966 by IBM researcher, G. M. Morton. The z-value of a point in multidimensions is
+calculated by interleaving the binary representations of its coordinate values. Once the data are sorted
+into this ordering, any one-dimensional data structure can be used, such as binary search trees, B-trees,
+skip lists, or hash tables. The resulting ordering can equivalently be described as the order one would
+achieve from a depth-first traversal of a quadtree, where `{x, y, ..., K}` are combined into a single
+ordinal value that is easily compared, searched, and indexed against other Morton numbers.
