3D Sky Cadaster

The 3D Sky Cadaster serves as a neutral and persistent database that records and preserves unique one-meter cubic parcels of open air between 20,000 m and 160,000 m above sea level.

Each parcel is defined with precise geospatial coordinates (latitude, longitude, and altitude), encoded using a Geohash10 for horizontal accuracy and a 1‑meter altitude step for vertical precision.

Canonical ID Structure

SKY-2026-2341

What it Stores

Geolocation, altitude, timestamp, cryptographic hash, and optional metadata

What It Doesn’t Assert

No property rights, legal ownership, or airspace control

Interoperability

A public API enables third‑party platforms to engage with sky parcels securely

Integrity & Provenance

Ensuring transparency, authenticity, and trust in every atmospheric record.

Cryptographic Hashing

Ensures every parcel record is sealed with a unique cryptographic fingerprint, making unauthorized changes impossible.

Immutable Timeline

Each update or event creates a new timestamped entry, preserving the full historical chain of the record.

Persistent Identifiers

Every parcel has a globally verifiable Canonical ID that links directly to its origin and record lineage.

Public Verification

Anyone can verify a record’s authenticity using its Parcel ID through the IAZB verification interface.

Provenance Tracking

Guarantees end‑to‑end traceability—from initial creation to every event logged thereafter.
