Copernicus Data Space STAC Catalogue API
SpatioTemporal Asset Catalogue (STAC) implementation for the Copernicus Data Space Ecosystem. Provides standardised metadata discovery for Earth Observation data including Sentinel missions. Follows the open STAC specification to enable interoperable access to asset-level metadata with spatial information, temporal coverage, and data specifications. Connects to the same underlying database as the OData interface, ensuring consistency across access methods.
