Abstract: HEALPix Hierarchical Equal Area iso-Latitude Pixelization, provides a framework for efficient discretization and fast analysis/synthesis of functions defined on the sphere. A suite of Fortran90 and IDL codes which provide useful applications is distributed to the community freely from the web site. HEALPix will be used to format the forthcoming data from the NASA MAP and ESA Planck missions to accurately map the anisotropy of the cosmic microwave background radiation at high resolution and at many frequency bands. Because of its inherent hierarchical tree structure (it is built as a self-similarly refinable quadrilateral mesh on the sphere) HEALPix can naturally support efficient data bases for objects distributed on the sphere.
