Electro-Optical extension for PySTAC
Decision gist · record as of 2026-08-14
Yes, if you are working with PySTAC and need to describe electro-optical sensor data. The package is actively maintained, has no security vulnerabilities, carries a permissive Apache-2.0 license, and integrates cleanly into the PySTAC ecosystem. Install friction is low. Not relevant for non-geospatial or non-STAC workflows.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; pystac-core must be installed.
- Low friction install with a pure-Python wheel.
- Actively maintained as of 2026-08-10 with recent release.

What it is and what it does
pystac-ext-eo is a PySTAC extension package that adds support for the Electro-Optical (EO) extension specification to the PySTAC library. It enables developers working with STAC (SpatioTemporal Asset Catalog) to describe electro-optical sensor data in a standardized way, including spectral band information, cloud cover percentages, and snow cover data. The package targets EO extension versions 1.1.0 and 1.0.0.
The package is a thin wrapper that integrates with PySTAC's extension system, requiring pystac-core and two sibling extensions (pystac-ext-projection and pystac-ext-view) as runtime dependencies. It is actively maintained, supports Python 3.10 through 3.13, and carries no known security vulnerabilities. Installation is straightforward via pip with a pure-Python wheel.
Use it for
- Building STAC catalogs for satellite or aerial imagery with standardized EO metadata.
- Querying and filtering imagery by spectral bands, cloud cover, or snow cover in STAC repositories.
- Integrating EO sensor metadata into geospatial data pipelines that use PySTAC.
- Publishing raster imagery collections with consistent, machine-readable sensor specifications.
