Tools for working withSpatioTemporal Asset Catalogs (STAC).

This organization has a large number of repositories in a variety of languages for many types of users.Here, we categorize each repository by its utility to users as described onSTAC website:

• 👩‍🍳Data providers produce geospatial data and index those data with STAC
• 💁‍♂️Developers build and maintain infrastructure to serve STAC to the world
• 😋Data users use STAC to find, visualize, and use geospatial data

Each table is sorted by the number of Github stars at the time of the file render.Any issues with or updates to these tables can be opened on the stac-utils.github.For more information on each repository, see its respective README.
