## AI interpretation — verify before relying

pyproj provides a Python interface to PROJ, enabling cartographic projections and coordinate system transformations for geospatial applications.

Verdict: pyproj is actively maintained with no known vulnerabilities, broad platform support via pre-built wheels for Python 3.11–3.13, and MIT licensing. Medium install friction reflects its compiled nature, but the extensive wheel coverage and active development (latest release 2025-08-14) make it a solid choice for geospatial work.
