It is commonly used in geospatial analysis to aggregate satellite imagery, digital elevation models, or other gridded data by administrative regions, study areas, or other polygon features. The package depends only on numpy and is available as precompiled wheels for modern Python versions (3.9\u20133.13) across macOS, Windows, and Linux, making installation straightforward on most systems.\n\nThe core use case is fast, accurate extraction of statistics (mean, sum, count, etc.) from raster cells that intersect with polygon geometries. Because it is implemented in C++, it is designed to handle large rasters and many polygons efficiently. The package is actively maintained, with no known security vulnerabilities, and is licensed under Apache 2.0, permitting commercial and private use.","worth_installing":"Yes. exactextract is a specialized, actively maintained tool for a well-defined geospatial task. It has no known vulnerabilities, a permissive license, minimal dependencies (numpy only), and precompiled wheels for all common platforms and Python versions. Install it if you need fast, accurate zonal statistics; skip it if your workflow uses simpler raster operations or if you are not working with polygon-raster overlays."},"id":"exactextract","links":{"html":"https://skillfed.io/packages/exactextract","md":"https://skillfed.io/packages/exactextract.md","pypi":"https://pypi.org/project/exactextract/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-12-01","license_spdx":null,"license_treatment":"permissive","name":"exactextract","python_support":"supports_current","summary":"Fast and accurate raster zonal statistics"},"popularity":{"monthly_downloads":183511,"position":10065,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.3.0"}
