To investigate the properties of large-scale structures of galaxies in the universe, we present an analysis of their spatial distribution at z<0.033. We used the LEDA extragalactic database containing over 1 million galaxies covering the all-sky and the SDSS data included in the public release DR1, yielding a sample of around 134 000 galaxies having a measured redshift in two survey areas representing 690 sq. degrees. The results of the study are 2D, 3D maps and magnitude number counts of galaxies, drawn from B-band samples.

Key words: cosmology: large-scale structure of Universe
