About:
PROJ is a library for performing conversions between geographic coordinate systems and cartographic projections. It provides a comprehensive set of tools for transforming geospatial data from one coordinate reference system (CRS) to another. Its main value is enabling accurate mapping and spatial analysis across different global and regional coordinate frameworks.

Key Features:

Comprehensive coordinate reference system (CRS) database
High-precision cartographic transformation algorithms
Support for 3D, 4D, and time-dependent coordinates
Command-line tools for batch processing
Extensive bindings for languages like C, C++, and Python

Use Cases:

Transforming map data between different national grid systems
Preparing satellite imagery and GIS data for analysis in a common projection
Supporting web mapping applications that require on-the-fly coordinate conversion

Alternatives:

GDAL – Includes coordinate transformation via its `ogr2ogr` tool, but uses PROJ as its underlying engine for many projections.
GeographicLib – Focuses on high-accuracy geodetic calculations and a smaller set of core projections, whereas PROJ offers a broader catalog of transformations.
