HEALPix - FeaturesHEALPix Data Analysis, Simulations and Visualization on the Sphere Introduction HEALPix is an acronym for Hierarchical Equal Area isoLatitude Pixelation of a sphere. As suggested in the name, this pixelation produces a subdivision of a spherical surface in which each pixel covers the same surface area as every other pixel. Purpose The original motivation for devising HEALPix was one of necessity.
