As an alternative, the Hilbert curve has been suggested as it has a better order-preserving behaviour, but here the calculations are much more complicated, leading to significant processor overhead. BIGMIN source code for both Z-curve and Hilbert-curve were described in a patent by H. Tropf.
For a recent overview on multidimensional data processing, including e.g. nearest neighbour searches, see Hanan Samet's textbook.
