pystac-ext-eo

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.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Extends PySTAC to add Electro-Optical extension support for describing sensor data, spectral bands, cloud cover, and snow cover in STAC catalogs.

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.

Install

pystac-ext-eo on PyPI

pip install pystac-ext-eo

uv add pystac-ext-eo

poetry add pystac-ext-eo

Installing pystac-ext-eo

Before you install

Low friction install with a pure-Python wheel. Actively maintained as of 2026-08-10 with recent release. Requires pystac-core and two other pystac extensions as runtime dependencies.

License in practice

Apache-2.0 permissive license allows commercial and private use with attribution; no copyleft restrictions.

Quickstart

pip install pystac-ext-eo

from pystac_ext_eo import eo

# Access EO extension methods on PySTAC items
item.ext.enable('eo')
item.ext.eo.set_bands([...])

Requires Python 3.10 or later; pystac-core must be installed.

Verify before relying

• Whether the package is actively used in production geospatial workflows beyond the download metrics.
• Performance characteristics when working with large STAC catalogs containing many EO items.
