Find

Discoverability in EarthCODE is provided by the Open Science Catalog, which exposes all published resources through a suite of open, standardized APIs for both human and machine access.

Discovery and Access

Catalog search uses the STAC API to perform spatial, temporal and attribute‑based queries against collections and items. Feature‑level retrieval is provided by OGC API – Features (or WFS), and multi‑dimensional data can be accessed via OGC WCS. Visualization layers may be exposed through OGC WMS and WMTS.

Core Discovery via STAC API

The primary programmatic interface for searching the catalog is the STAC API. This is the main endpoint for machine-to-machine queries. It enables complex spatial, temporal, and attribute-based queries to find relevant data products and experiments. The effectiveness of these searches relies on the rich, standardized metadata described in the Metadata Definitions page.
