STAC stands for "SpatioTemporal Asset Catalog". It's a standardized framework for indexing, cataloging, and describing geospatial data. It makes Hydrosat data easier to work with, especially if you're integrating it with data from other sources.
Each STAC item includes several assets representing the individual data and metadata files associated with the scene. Items from different collections have different assets, as defined on our page.
You have full access to the scenes you've ordered and thumbnail-only access to the rest of the catalog.
