Satellite extension for PySTAC
Decision gist · record as of 2026-08-14
Yes, if you are working with PySTAC catalogs that include satellite imagery. The package is actively maintained, has no known vulnerabilities, installs with minimal friction, and provides the standard way to handle satellite-specific metadata in the STAC ecosystem. Not necessary if your catalogs do not use satellite metadata or do not rely on PySTAC.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- Low install friction; pure Python wheel with a single runtime dependency on pystac-core.
- Package is actively maintained with a recent release and no known vulnerabilities.

What it is and what it does
pystac-ext-sat is a PySTAC extension package that adds support for the Satellite Extension specification (v1.0.0) to the PySTAC catalog framework. It provides typed access to satellite-specific metadata fields such as orbit state vectors, relative orbit numbers, and platform-specific identifiers that describe Earth observation imagery and related raster data. The package is designed for developers working with satellite imagery catalogs who need to read, validate, or work with standardized satellite metadata within the STAC ecosystem.
The package depends only on pystac-core and installs as a pure Python wheel, making it lightweight and easy to integrate into existing PySTAC workflows. It targets modern Python versions (3.10 through 3.13) and is actively maintained, with versioning tied to the extension specification version it supports.
Use it for
- Read satellite orbit and platform metadata from STAC items describing Earth observation data.
- Validate that satellite imagery catalogs conform to the Satellite Extension specification.
- Build tools that filter or organize satellite imagery by orbit characteristics or platform identifiers.
- Integrate satellite metadata into PySTAC-based data discovery or processing pipelines.
