Index Structure & Access Protocol

Each Pithos index base consists of the following off-heap files per LROC NAC image product:

  • : PolarQuant-Hadamard 384-dim binary vector index base
  • : Unique tile identity mapping array
  • : Georeferencing metadata & spatial coordinates
  • ... : Multi-resolution hierarchical quantization tiers
  • : Python metadata dictionary
