What is STAC Server?¶

STAC Server is a production-ready implementation of the STAC API specification with an OpenSearch backend. It provides a scalable, standards-compliant API for searching and accessing spatiotemporal data.

Key Features¶

Powerful Search: Search across millions of spatiotemporal items with complex queries, filters, and geospatial operations.
STAC Extensions: Built-in support for Transaction, Query, Filter, Sort, Fields, Aggregation, and Context extensions.
Aggregations: Analyze data distributions with frequency histograms, temporal aggregations, and spatial grids.
Cloud Native: Serverless deployment on AWS with Lambda, API Gateway, OpenSearch, and SNS/SQS for ingestion.
Production Ready: Battle-tested with Element 84's Earth Search.

Architecture¶

STAC Server uses a serverless architecture on AWS:
