...

The ability to portray our cloud-based data holdings as SpatioTemporal Asset Catalogs (STAC) is an essential component of EOSDIS’ the ESDIS cloud evolution strategy. 

...

The Common Metadata Repository will provide a STAC API that will allow discovery of all EOSDIS’ ESDIS cloud-based holdings, subject to established access controls and suitability¹.

...

1. As a science user in a notebook environment, I would like to use STAC libraries to locate STAC catalogs representing my data of interest in the cloud. I would use those catalogs to interact with standard geospatial analysis libraries such as GeoPandas, intake, XArray and DASK to produce efficient, cost-effective, reproducible analysis. This notebook environment may be local or cloud-based.
2. As a science user, I would like to discover data of interest using STAC tooling such as STACBrowser.

Improvements

EOSDIS ESDIS has a commitment to providing an efficient, intuitive user experience when leveraging our holdings. Consequently, we have identified several areas with respect to STAC that could be improved in this regard.

...

The S3 credentials improvements can be mitigated by outreach and documentation in the short term.
