# pystac-ext-grid — Grid extension for PySTAC

License: permissive · Maintenance: active · Downloads: 4.0M/mo

## What it is and what it does

pystac-ext-grid is a PySTAC extension package that adds support for the Grid Extension specification to the PySTAC library. It allows you to describe and catalog gridded data products—such as satellite imagery organized under MGRS, MODIS, or other tiling schemes—by attaching standardized grid metadata to STAC items and collections. The package targets the Grid Extension specification versions 1.1.0 and 1.0.0.

You use it when you need to document which grid system your raster or imagery data follows, making it discoverable and interpretable within a STAC catalog. It depends only on pystac-core and installs with minimal friction. The package is actively maintained, supports Python 3.10 through 3.13, and carries no known security vulnerabilities.

Use it for:

- Catalog satellite imagery organized under MGRS grid codes within a STAC collection.
- Document MODIS-tiled data products with standardized grid metadata.
- Add grid specifications to existing PySTAC items to enable grid-aware discovery.
- Build searchable geospatial data catalogs that expose grid tiling information.
- Integrate gridded raster data into STAC workflows with proper grid provenance.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Extends PySTAC to describe gridded data products by specifying grid codes like MGRS or MODIS tiling schemes that data corresponds to.

Yes. The package is actively maintained, has no vulnerabilities, installs with low friction, and carries a permissive Apache-2.0 license. Install it if you are working with PySTAC and need to describe gridded data products or integrate grid metadata into STAC catalogs.

## Install

pip install pystac-ext-grid
uv add pystac-ext-grid
poetry add pystac-ext-grid

## Installing pystac-ext-grid

Before you install: Low friction install with a single runtime dependency (pystac-core). Active maintenance with a recent release (4 days old) and no known vulnerabilities.

License in practice: Apache-2.0 permissive license allows commercial and private use with minimal restrictions; suitable for most projects.

Quickstart:

pip install pystac-ext-grid

from pystac_ext_grid import GridExtension

# Access grid extension on a PySTAC item
grid_ext = GridExtension.ext(item)

Requires Python 3.10 or later; pystac-core must be installed as a runtime dependency.

Verify before relying:

- Whether the package handles all common grid code systems beyond MGRS and MODIS.
- Performance characteristics when working with large catalogs or many grid specifications.
