Label extension for PySTAC
Decision gist · record as of 2026-08-14
Yes. If you are building or consuming STAC catalogs that include labeled training data, this extension is the standard way to describe that metadata. Low install friction, active maintenance, permissive license, and no security issues make it a straightforward addition to a PySTAC workflow.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 as a runtime dependency.
- Low friction: pure Python wheel with a single runtime dependency on pystac-core.
- Active maintenance with a recent release (4 days old) and no known vulnerabilities.

What it is and what it does
pystac-ext-label is a PySTAC extension package that implements the STAC Label Extension specification (v1.0.0 and v1.0.1). It adds structured fields to STAC catalogs and items for describing labeled training data used in machine learning workflows, including label types, classification schemes, annotation tasks, and summaries of label distributions across datasets.
The package is a thin wrapper around the Label Extension schema, designed to integrate seamlessly with PySTAC's core catalog and item APIs. It targets developers building machine learning data pipelines who need to catalog, discover, and share labeled imagery or raster data through STAC-compliant metadata. The package is actively maintained, supports modern Python versions (3.10–3.13), and carries no known security vulnerabilities.
Use it for
- Catalog labeled satellite or aerial imagery datasets for machine learning model training and validation.
- Describe annotation tasks and label distributions in STAC items to document data preparation workflows.
- Integrate labeled training data metadata into STAC repositories for reproducible ML experiments.
- Share labeled geospatial datasets with consistent, standardized metadata across teams and projects.
