Abstract: Spherical pixelization schemes are reviewed that allow analyzing extended emission and, in particular, the cosmic microwave background. Problems with implementing different schemes are considered. The nonhierarchical Gauss–Legendre sky pixelization (GLESP) approach is discussed in detail.

Keywords: sky pixelization, data analysis, cosmic microwave background.
