wcslib

WCSLIB is a C library, supplied with a full set of Fortran wrappers, that
implements the "World Coordinate System" (WCS) standard in FITS (Flexible Image
Transport System). It also includes a PGPLOT-based routine, PGSBOX, for drawing
general curvilinear coordinate graticules and a number of utility programs.
The FITS data format is widely used within the international astronomical
community, from the radio to gamma-ray regimes, for data interchange and
archive, and also increasingly as an online format. It is described in:

"Definition of The Flexible Image Transport System (FITS)",
FITS Standard, Version 3.0, 2008 July 10.
