AEF-v1 embeddings Rasteret Collection

This dataset is a read-ready [Rasteret](https://github.com/terrafloww/rasteret) collection derived from the AlphaEarth Foundations (AEF) Embedings COGs files and STAC-GeoParquet index from Source Coop TGE-labs AEF repository, enriched with COG header metadata. It covers the full 2018-2024 COGs available in Source Coop buckets, and will be updated in future when 2025 embeddings comes out. It is intended for Rasteret users who want to skip the build/enrich step and start directly from a filterable

What's in it

Data offered docs-verified: AlphaEarth Foundations annual satellite embeddings, per-band COG metadata (A00–A63) · Tile-level GeoParquet index (crs, path, year, utm_zone, bbox, geom) · Per-band COG header metadata for direct pixel reads from upstream COGs
Coverage docs-verified: Global · 2018-2024
Update frequency docs-verified: Ad hoc: to be updated when 2025 embeddings are released (no schedule stated)
Formats docs-verified: GeoParquet 1.1 · Parquet · Cloud Optimized GeoTIFF header metadata (pixels read from upstream COGs)
Access docs-verified: Public, anonymous HTTPS/S3 access (no login stated); index licensed CC-BY-SA-4.0, underlying AEF embeddings CC-BY-4.0 with required attribution

Useful for

Use cases llm-inferred: Pre-filter AEF annual embedding tiles by bbox, year and UTM zone before reading pixels for a site · Screen which tiles cover a catchment or site, then compare annual embeddings across 2018-2024 for change context · Join the tile index to project label or survey datasets to build embedding-based land-cover or habitat features
Audience llm-inferred: GIS analysts · remote sensing analysts · ecologists · hydrologists · planners

Limitations

Constraints docs-verified: Metadata index only; embedding pixel arrays are not stored in Parquet and must be read from upstream COGs · Depends on upstream AEF COG URLs remaining available · Optimised for Rasteret and Arrow-native tooling rather than full-scan throughput · Derived index, not a replacement for the upstream source dataset · 2025 embeddings not yet included · Attribution text required when used
