# Morton code calculator

Interleave the bits of two 16-bit coordinates into a Morton code, or decode a code back to x and y, with the binary interleaving shown.

Enter x and y to interleave them.

The Z-order curve interleaves bits so that nearby coordinates land in nearby codes, which is why spatial indexes and geohash-style tiles use it. The property is one-directional in practice: points that are close in space get close codes, but close codes can also come from distant points across a Z boundary, so equal codes never mean equal neighbors. This page does plain bit math in one direction at a time, in this tab, with nothing fetched.
