Voyager STAC Implementation

Voyager supports the SpatioTemporal Asset Catalog (STAC) API, an open specification aimed at enhancing the discovery and interoperability of geospatial data. Our platform incorporates both the static and dynamic aspects of STAC: it provides a structured catalog for geospatial assets and offers a dynamic, query-responsive STAC API endpoint. This integration, conforming to OGC API – Features and detailed through OpenAPI specifications, underlines our commitment to improving the management and accessibility of geospatial information in a practical and user-focused manner.

Voyager consumes and exposes STAC API:

Consume: Connecting to and Indexing with STAC API including enhanced Metadata through Data Enrichment and Conditioning

Voyager’s implementation of the STAC API extends beyond mere consumption and indexing of STAC-compliant data sources. It harnesses our platform’s robust data enrichment and conditioning capabilities to enhance the STAC metadata itself. As Voyager connects to and aggregates data from various STAC endpoints, it applies advanced processing techniques to enrich and refine this metadata. This enrichment process involves adding more context, improving metadata accuracy, and ensuring that the data is more relevant and informative.

This enhanced metadata significantly bolsters the value of the data catalog, making it not just a repository, but a rich, intelligently curated resource. The result is a more robust and detailed catalog that not only aids in more effective data retrieval but also plays a pivotal role in data governance and implementing zero-trust policies. By ensuring that the metadata is comprehensive and precisely tailored, Voyager aids organizations in maintaining stricter control over their data assets, ensuring compliance with governance standards, and enhancing the security and reliability of data access and usage.

Through this enriched approach to consuming STAC metadata, Voyager elevates the utility of geospatial data, transforming how organizations access, interpret, and leverage this information in their decision-making processes.

Expose: Exposing the Enhanced Voyager Registry as a STAC Compliant Service
In addition to consuming data, Voyager can also expose its enriched registry as a STAC compliant service. This functionality enables other systems and users to access Voyager's extensive and diverse geospatial data repository through a STAC-compliant interface. The exposure of Voyager’s registry in this manner ensures that the data is not only accessible within the Voyager ecosystem but also interoperable with other STAC-compatible systems, expanding the reach and usability of the indexed geospatial information.
