What is HEALPix?¶
HEALPix (Hierarchical Equal Area isoLatitude Pixelisation) is an algorithm for pixellizing a sphere that is sometimes used in Astronomy to store data from all-sky surveys, but the general algorithm can apply to any field that has to deal with representing data on a sphere.
More information about the HEALPix algorithm can be found here:
