Python library for creating and working with STAC catalogs

sat-stac

This is a Python 3 library for working with Spatio-Temporal Asset Catalogs (STAC). It can be used to

• Open and traverse STAC catalogs
• Download assets from STAC Items, using templated path names
• Save and load Self-contained STAC catalogs
• Create and update catalogs*
• Add or remove a STAC Collections of Items from a catalog*

• sat-stac works for small catalogs or a small rate of updates. It is more useful for reading existing catalogs (either static or dynamic). For creating or large updating of catalogs, PySTAC is the better alternative.
