We study the interferometric observation of intensity and polarization anisotropies of a stochastic gravitational wave background (SGWB). We show that the observed correlated data is defined in the group manifold of the three-dimensional rotation. Explicit correlation between two detectors in the interferometry experiments such as LIGO-VIRGO and KAGRA is constructed in terms of the Wigner D-functions. Our results reveal the topology of the data structure and provide a systematic way for constructing data pipelines to estimate the power spectra of the SGWB anisotropies.
