eodag’s interfaces are compliant with the SpatioTemporal Asset Catalog
STAC API providers can be configured to be used for search and download using EODAG. Some providers (astraea_eod, earth_search, usgs_satapi_aws) are already implemented and new providers can be dynamically added by the user. Static catalogs can also be fetched by EODAG.
EODAG can run as STAC API REST server and give access to configured providers data through a STAC compliant search API.
