It implements the Projection Extension specification, enabling you to describe the geospatial projection of raster data through fields like EPSG code, WKT2 representation, PROJJSON, geometry bounds, centroid, shape, and coordinate transformation parameters.\n\nThe package supports multiple versions of the Projection Extension specification (v2.0.0, v1.2.0, v1.1.0, v1.0.0) and is designed to integrate seamlessly with PySTAC workflows. It depends only on pystac-core, making it lightweight to add to existing STAC catalog tooling. The package is actively maintained and targets modern Python versions (3.10\u20133.13).","worth_installing":"Yes, if you are building or extending STAC catalogs for geospatial raster data. The package is lightweight, actively maintained, has no known vulnerabilities, and provides a standard way to attach projection metadata. Install it when you need to document spatial reference systems in PySTAC items or collections."},"id":"pystac-ext-projection","links":{"html":"https://skillfed.io/packages/pystac-ext-projection","md":"https://skillfed.io/packages/pystac-ext-projection.md","pypi":"https://pypi.org/project/pystac-ext-projection/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-10","license_spdx":null,"license_treatment":"permissive","name":"pystac-ext-projection","python_support":"supports_current","summary":"Projection extension for PySTAC"},"popularity":{"monthly_downloads":3981671,"position":2422,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"2.0.1"}
