It converts between human-readable coordinate tuples and the compressed format used by mapping APIs, supporting both (lat, lon) and GeoJSON (lon, lat) coordinate orders. The package has no runtime dependencies and works with Python 3.8 and above.\n\nTypically used in mapping and geolocation applications to reduce bandwidth when transmitting routes, paths, or coordinate sequences over the network. You provide a list of coordinate pairs and a precision level, and the encoder produces a compressed string; the decoder reverses the process. The library is a port of Mapbox's polyline implementation with additional features, making it suitable for applications that need to serialize geographic data efficiently.","worth_installing":"Yes, if you need to work with Google's Encoded Polyline format. The package is lightweight, dependency-free, and widely used (top 5000 on PyPI). Maintenance is aging but the code is stable and no vulnerabilities are known. The MIT license is permissive. Install it if your application requires polyline encoding/decoding; skip it if you don't work with this specific format."},"id":"polyline","links":{"html":"https://skillfed.io/packages/polyline","md":"https://skillfed.io/packages/polyline.md","pypi":"https://pypi.org/project/polyline/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-12-02","license_spdx":null,"license_treatment":"unclear","name":"polyline","python_support":"supports_current","summary":"A Python implementation of Google's Encoded Polyline Algorithm Format."},"popularity":{"monthly_downloads":2499132,"position":3037,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"2.0.4"}
