stac-hash

Sortable spatio-temporal hashes for STAC items.

Our simple hashing algorithm turns a (datetime, point) pair into a single u64 hash. The hash is a Morton code in space and time, which makes the hash useful as a sort key or an index prefix for range scans.

We have Python and Rust packages.
