brew install proj v9.8.1 MIT

C library for cartographic coordinate system transformations and map projections.

Why you might care

PROJ is the standard geospatial library for converting between geographic coordinate systems, datums, and projections—essential for GIS software, mapping tools, and geospatial analysis. It handles complex transformations (lat/lon to UTM, Web Mercator, etc.) with high accuracy and is widely integrated into PostGIS, GDAL, and other geospatial stacks.
