Detailed Description

Header of a serialized tile index blob (version 2).

Tile assignment uses the BOTTOM tile_bits bits of the 30-bit bit-reversed Morton sort key, which equal the TOP tile_bits bits of the plain Morton code. These bits identify the coarsest spatial octant, so each tile covers one spatial cell of a (2^(tile_bits/3))³ grid over the cloud's bbox. The cloud bbox (lo, hi) stored here is required to recompute sort keys at serve time without re-reading all point data.
