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
