This
note presents HiPS, a hierarchical scheme for the
description,
storage and access of sky survey data. The principle is
based on
hierarchical tiling of sky regions at finer and finer
spatial
resolution which facilitates a progressive view of a survey,
and
supports multi-resolution zooming and panning. HiPS uses the
HEALPix
tessellation of the sky as the basis for the scheme and is
implemented as a simple file structure with a direct
indexing scheme
that leads to practical implementations.</big></font></big></i>
