Cartographic projection software

PROJ is a standard UNIX filter function which converts geographic longitude and latitude coordinates into Cartesian coordinates (and vice versa), and it is a C API for software developers to include coordinate transformation in their own software.

The main purpose of PROJ is to transform coordinates from one coordinate reference system to another. This can be achieved either with the included command line applications or the C API that is a part of the software package.
