IPLD-Encoded GeoTIFFs
This early Astral scheme replaced GeoTIFF file directories with IPLD data structures, giving tiles and overviews individual content identifiers for verifiable, efficiently queryable raster data.
Purpose
Some workflows incorporate raster imagery, so we wanted a verifiable raster data management scheme with spatially aware fetching for efficiency.
Approach
An IPLD encoding for GeoTIFFs that replaces the file directory with content-addressed tiles and overviews, each carrying its own content identifier.
Status
Archived experiment, 2021.

Astral API
PreviewThe Astral API indexes location attestations from the Ethereum Attestation Service across chains and serves them through OGC-compliant REST and GraphQL interfaces backed by PostGIS.
Astral Compute
PreviewAstral Compute evaluates spatial predicates -- distance, containment, intersection -- inside a trusted execution environment and returns cryptographically signed results that a third party can verify.
Astral Docs: Location Proofs
ActiveThe Astral documentation describes location proofs as verifiable artifacts pairing a claim about the timing and position of an event with corroborating evidence, graded along a certainty spectrum rather than treated as absolute.
Astral Docs: Location Records
ActiveThe Astral documentation describes location records -- signed, verifiable location data artifacts that add cryptographic attribution and integrity checking to raw geospatial data.
