Cloud-Native Geospatial isn't just for data, it's for metadata too! stac-geoparquet is an open, community specification for the SpatioTemporal Asset Catalog (STAC) spec that can be used for storage and analytics.
stac-geoparquet is an open, community data storage specification for the SpatioTemporal Asset Catalog (STAC) ecosystem. It's compressible and structured, making it an efficient storage format that can be queried "at rest" with no external services. In this talk, we'll walk through the specification itself, its history, and where it's going. The talk will include:
- A roadmap for the specification
- Discussion and comparison of tooling for reading and writing
- Demonstration of querying stac-geoparquet at rest via DuckDB with STAC API parameters
- Performance metrics relative to database-backed APIs and services
- Analysis of the use of stac-geoparquet at huge (planetary) scales, including transaction support
