Tools for working with SpatioTemporal 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 on STAC 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.

Note
Until 2024-12-24, this organization had discussions enabled. This was confusing, because there is also a STAC Software topic on the STAC spec discussions board. On 2024-12-24, we disabled discussions for this org — folks should use https://github.com/radiantearth/stac-spec/discussions/categories/stac-software for STAC Software related questions. For more background, see this discussion topic. To see the old stac-utils discussions, go to the .github repo's discussions page.
For general questions, use the "STAC software" category stac-spec discussions. For repository-specific questions or issues, use that repository's discussions or issues page. For issues with this text, use the organization's .github repository's issues page.
