This is the Homepage for the HPIC project, an implementation of the healpix method for pixelizing the sphere. The HPIC library and tools are licensed under the GNU General Public License, and you can find a copy of the license here. Why use HPIC instead of / in addition to other healpix tools?
  • Clean, object-oriented interface
  • Written in C - easily linked with C/C++ code
  • Perl interface, other language bindings possible
  • Superior FITS routines
  • Command line utilities to manipulate healpix FITS files
