Classification extension for PySTAC
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained, has no known vulnerabilities, uses a permissive license, and provides essential extension support for STAC-based classification workflows. Install friction is low and Python version support is current. Suitable for projects that need to catalog and describe classified raster or vector data within 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 with a pure-Python wheel.
- Active maintenance with a recent release (4 days old) and a commit history through 2026-08-10.

What it is and what it does
pystac-ext-classification is a PySTAC extension package that adds support for the STAC Classification Extension specification. It enables developers to attach categorical metadata to raster and vector data items, describing classification schemes with class names, descriptions, color hints, and regional mappings. The package targets multiple versions of the Classification Extension specification (v2.0.0, v1.1.0, v1.0.0) and is versioned to match the extension specification it implements.
The package depends on pystac-core for core STAC functionality and pystac-ext-raster for raster-specific support. It is actively maintained, with a production-stable status and support for Python 3.10 through 3.13. Installation is straightforward via a pure-Python wheel with no compiled dependencies.
Use it for
- Annotate raster imagery with classification metadata (e.g., land cover classes, confidence scores) in STAC catalogs.
- Define and document classification schemes for machine learning training datasets with class names and color hints.
- Map regional classification variants to the same STAC item for multi-region geospatial workflows.
- Extend PySTAC items with categorical data descriptions for vector features or segmentation masks.
