proj.4 is 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.
See http://proj4.org/
Note: it is used by the GDAL library, already in OSS-Fuzz.
